Fractional CTO Recruitment

Fractional CTO Executive Search

A fractional Chief Technology Officer (CTO) provides board-level technology leadership on a part-time or flexible basis — giving your business the technical strategy, engineering oversight, and delivery leadership it needs to scale, without the cost or commitment of a full-time hire. Exec Capital places experienced fractional CTOs with high-growth businesses, PE-backed companies, and established organisations across the UK. Every search is run by our specialist team, with Adrian Lawrence FCA overseeing each mandate.

A fractional CTO typically works one to three days per week, operating as a genuine member of your leadership team — attending executive meetings, owning technical strategy and its execution, and accountable for measurable delivery outcomes. Whether you need to scale your technology platform, lead a digital transformation, strengthen engineering capability, or bridge a gap at the top of your technology function, Exec Capital identifies and places the right CTO quickly. We agree the timetable with you at briefing, so the search runs to your deadlines rather than a generic one.

What Is a Fractional CTO?

A fractional CTO is a senior technology executive who works with your business on a defined part-time basis — typically one to three days per week — providing board-level technical leadership without the cost or commitment of a permanent appointment. The role carries the same responsibilities as a full-time CTO: technology strategy, systems architecture, engineering team leadership, product and platform delivery, cybersecurity oversight, and ensuring technology supports commercial objectives.

The CTO role is primarily focused on the external technology function — product, engineering, platform, and innovation. This distinguishes it from the CIO, which typically focuses on internal IT systems, infrastructure, and operations. In many businesses the roles overlap or are combined, particularly at growth stage. Exec Capital can advise on which profile best fits your brief and can search across both disciplines.

Fractional CTOs typically work with a portfolio of clients simultaneously, bringing cross-sector technology experience from multiple business environments and growth stages. A fractional CTO who has scaled three SaaS platforms, delivered two cloud migrations, and led engineering teams through two funding rounds brings a pattern recognition and breadth of experience that most full-time technology executives simply cannot match.

What the fractional CTO role looks like in practice

The fractional CTO role is easiest to understand by what fills the days. In a typical month the CTO sits in the leadership meeting, runs or attends engineering planning, reviews architecture decisions that have consequences beyond the current sprint, meets the people building the product, and spends time with the founders or CEO on the technology side of the business plan. Between sessions they are usually reachable for decisions that cannot wait — a production incident, a supplier dispute, a candidate who needs a final interview — on terms you agree at the start.

What separates a fractional CTO from a technical adviser is accountability. An adviser offers views; a fractional CTO owns outcomes. They hold the technology roadmap, they answer to the board or investors for delivery, and they make the calls that a senior developer should not have to make alone: what to build and what to buy, when to pay down technical debt and when to live with it, which hires to make first, and how much risk the platform can carry. The best fractional CTOs are explicit about this from day one, and the engagement letter should say so too.

The role is also defined by what it does not do. A fractional CTO is not a contract developer, and if the brief is mainly about writing code you are better served by an engineer or a delivery partner. Nor is a fractional CTO a substitute for a full engineering team. Their job is to make the people and suppliers you already have more effective, to set the standards they work to, and to give the board confidence that the technology will carry the business plan.

Fractional CTO, Interim CTO, and Part-Time CTO — What’s the Difference?

Exec Capital recruits across all four models. If you are unsure which structure best fits your current situation, our team can advise on your initial call.

Fractional CTO vs Interim CTO vs Dev Agency vs Permanent CTO

Many businesses weighing up a fractional CTO are really choosing between four different ways of getting technology leadership. The table below sets them side by side. The right answer depends less on budget than on what decision you are trying to get made, who will be accountable for it, and how long the need will last.

Two points are worth drawing out. First, a development agency and a fractional CTO are not alternatives so much as complements: one of the most common reasons businesses appoint a fractional CTO is to oversee an agency — to set the specification, review the work, challenge estimates and make sure the company owns what it is paying for. Second, “CTO-as-a-service” offerings vary widely. Some provide a named, experienced individual; others provide access to a pool. If you are buying technology leadership rather than development capacity, insist on knowing exactly who will be accountable.

Other ways to hire a CTO. This page covers the fractional format. If you need someone full-time for a defined period — covering a departure or running a critical programme — see our interim CTO service. For a permanent appointment, our CTO recruitment team runs full retained searches. If the need is internal IT, infrastructure and systems rather than product engineering, a fractional CIO may be the better fit. And if you need several part-time leaders across finance, operations and technology, our fractional C-suite practice can put the team together.

When Does a Business Need a Fractional CTO?

Scaling a technology platform ahead of growth

Technology businesses and scale-ups frequently reach a point where the architecture that got them to their current stage cannot reliably take them to the next. Performance degrades under load, engineering velocity slows, and technical debt accumulates faster than it is resolved. A fractional CTO provides the architectural authority and delivery leadership to restructure the technology function — improving platform scalability, strengthening engineering practices, and ensuring the technology stack can support the next phase of growth.

No CTO in post — engineering being led by developers

Many early-stage and growth businesses operate without a formal CTO, with engineering leadership sitting with a senior developer or VP of Engineering. This works until it doesn’t — when strategic technology decisions need to be made at board level, when investors expect a credible technology leader, or when the organisation needs executive accountability for delivery. A fractional CTO fills this gap immediately, providing board-level technology leadership on a cost structure that fits the current stage.

Digital transformation or platform modernisation

Businesses migrating from legacy systems, implementing new platforms, or modernising their technology stack need executive-level technology leadership to own the programme. A fractional CTO defines the transformation architecture, manages technology vendor relationships, holds engineering and delivery teams accountable, and ensures the programme delivers its commercial objectives on time and on budget — without requiring a full-time hire for what may be a 12 to 24-month initiative.

Fundraising and investment readiness

Technology due diligence is a standard part of PE investment and VC funding processes. Investors assess technology architecture maturity, platform scalability, engineering team capability, cybersecurity posture, and technical debt levels. A fractional CTO prepares the technology function for external scrutiny — addressing known weaknesses, building documentation, improving engineering processes, and providing credible technology leadership narrative for the investment process.

Product and engineering leadership for a scaling team

As engineering teams grow from 5 to 20 to 50 people, the management and delivery structures that worked at smaller scale break down. A fractional CTO builds the engineering organisation — implementing the delivery frameworks, team structures, hiring processes, and engineering culture that allow a growing technology function to remain productive and cohesive at scale.

CTO departure or leadership gap

When a CTO leaves unexpectedly, the engineering function loses its strategic anchor and the product roadmap loses its technical owner. A fractional CTO maintains continuity — providing technical direction, managing the engineering leadership team, and protecting ongoing product and platform programmes — while the permanent search runs in parallel. The handoff to the incoming permanent CTO can be managed cleanly from day one of the fractional engagement.

Building an AI roadmap that the business can actually deliver

Most of the fractional CTO enquiries we now receive include an AI question. Some come from AI-native businesses whose product depends on models and data pipelines; others come from established companies under pressure from boards and customers to “do something with AI”. In both cases the need is the same: someone senior enough to separate what is useful from what is fashionable, to decide whether to build, buy or integrate, to put proper controls around data, security and model risk, and to make sure the cost of running AI features is understood before they ship. A fractional CTO with hands-on AI delivery experience can set that roadmap without the business committing to a full-time AI hire before it knows what it needs. Where the brief is narrower and centres on AI governance and adoption across the whole business, a fractional Chief AI Officer may be the better fit.

Overseeing an outsourced development partner

Plenty of early-stage companies build their first product through an agency or offshore team. It is a sensible way to get to market, but it leaves the founders buying something they cannot fully evaluate. A fractional CTO sits on the client side of that relationship: writing or reviewing the specification, challenging estimates, checking code quality and security, making sure the company holds the repositories, credentials and documentation, and planning the eventual move to an in-house team. The cost of the fractional engagement is often recovered in avoided rework alone.

Is a Fractional CTO Right for You?

A fractional CTO is not the right answer for every business. The checklist below reflects the situations where we see the model work best. If several of these describe you, a fractional engagement is worth a serious look; if none do, you may need a developer, a delivery partner or a full-time CTO instead.

• You are between pre-seed and Series A. You need senior technical judgement and investor credibility, but a full-time CTO salary and equity grant would take too much of the round. A fractional CTO gives you the leadership now and helps you decide when a permanent hire makes sense.
• Technical due diligence is coming. An investor, acquirer or lender is going to look hard at your platform, code, security and team. You want someone who has been through it from the company side to find the problems first and present the technology credibly.
• An agency or contractor is building your product. You are paying for development you cannot fully assess, and you want an independent senior person on your side of the table.
• You need an AI roadmap. The board or your customers expect a view on AI, and you need someone to set priorities, choose between building and buying, and put sensible guardrails in place.
• You are hiring your first engineers. You need someone to define the roles, run technical interviews, set engineering standards and make sure the first hires are the right ones — mistakes here are expensive to unwind.
• Your developers have outgrown informal leadership. A strong senior developer has been acting as de facto CTO, but strategic and board-level decisions are now beyond the role.
• Your platform is creaking. Reliability, performance or security issues are starting to affect customers or the sales pipeline, and nobody owns the fix end to end.
• You want to test the role before committing. You are not yet sure what a permanent CTO should look like, and a fractional engagement will shape the brief.

The model is less suited to businesses that need a technology leader on site every day to run a large engineering organisation, or where the main gap is coding capacity rather than leadership. In those cases we will tell you so, and point you towards whether a VP of Engineering or a CTO should come first or the right permanent search.

Fractional CTO for Start-ups, Scale-ups and Established Businesses

The title is the same, but the job changes a great deal with the stage of the business. Being clear about which version you need makes the search sharper and the engagement more productive.

Start-ups: the technical co-founder you do not yet have

In a pre-seed or seed business the fractional CTO often fills the gap left by a missing technical co-founder. The work is practical and fast-moving: choosing the initial stack and hosting, deciding what to build and what to buy, writing or reviewing the specification for a first product, selecting and managing a development partner or first engineers, and being the credible technical voice in investor meetings. Cost discipline matters — cloud bills and tooling subscriptions can quietly consume runway — and so does keeping options open, because the product will change as the business learns. The right candidate here has usually built something from nothing before and is comfortable with ambiguity.

Scale-ups: structure without bureaucracy

Between Series A and Series B the challenge shifts from building a product to building an engineering organisation. Teams grow, the original developers become managers whether or not they want to, and processes that lived in people’s heads need writing down. The fractional CTO puts in the structures — team design, career paths, delivery rhythms, on-call and incident handling, security controls — that let the team keep shipping as it doubles. Often they also help recruit a VP or Head of Engineering who will run day-to-day delivery, while they continue to own strategy and board reporting.

Established businesses: leadership for a defined change

In a mature business without a technology executive, the fractional CTO is usually brought in for a specific purpose: a platform replacement, a move to the cloud, a data or AI programme, a cybersecurity uplift, or integration after an acquisition. The emphasis is on governance and stakeholder management as much as technology — working with finance on business cases, with operations on change, and with the board on risk. Candidates for these roles typically have transformation experience in larger organisations and the patience to bring a long-established team with them.

What a Fractional CTO Delivers

Technology strategy and architecture

• Develop and own technology strategy aligned with commercial and product objectives
• Define systems architecture and technical standards for the engineering organisation
• Build technology roadmaps covering platform, product, and infrastructure
• Provide board and investor-level technology narrative and reporting

Engineering leadership and team development

• Lead, develop, and manage engineering teams and technology functions
• Build engineering culture, practices, and delivery frameworks
• Support the recruitment and development of technical talent
• Manage third-party technology partners, agencies, and outsourced engineering

Product and platform delivery

• Own the product and platform delivery roadmap at executive level
• Improve engineering velocity and delivery predictability
• Resolve technical blockers and escalation points in the delivery process
• Ensure engineering output aligns with commercial and product priorities

Cybersecurity and technical governance

• Assess and strengthen cybersecurity posture and incident response capability
• Implement technical governance frameworks appropriate to business scale
• Ensure compliance with relevant standards — ISO 27001, Cyber Essentials, GDPR, SOC 2
• Build and maintain technology risk frameworks for board and investor reporting

For many smaller UK businesses the practical starting point is the government-backed Cyber Essentials scheme run by the National Cyber Security Centre, which sets a baseline of technical controls and is increasingly asked for by larger customers and public-sector buyers. A fractional CTO will usually get that baseline in place before moving on to heavier frameworks such as ISO 27001 or SOC 2, where customers require them.

Technical due diligence and investor support

• Prepare technology function for investment or acquisition due diligence
• Build credible technical narrative for investor presentations
• Support M&A technology integration planning and execution
• Assess and document technical debt, platform scalability, and architecture maturity

What a Fractional CTO Does in Month 1, Month 3 and Month 6

Every engagement is different, but well-run fractional CTO appointments tend to follow a recognisable pattern. Setting expectations against this shape at the start makes it much easier to judge whether the engagement is working. It also gives the board a simple way to review progress at each stage.

Month 1: assess, stabilise and agree priorities

• Meet the founders, leadership team, engineers and key suppliers; understand the business plan the technology has to support
• Review the architecture, codebase, infrastructure, security controls, delivery process and costs, and write a short, candid assessment
• Check the basics that are often missed: who holds the code repositories, cloud accounts, domain names and credentials; whether IP has been properly assigned; whether backups and access controls work
• Fix anything that poses an immediate risk to customers or the business
• Agree a short list of priorities for the next quarter with the CEO or board, and how progress will be reported

Month 3: a plan in motion

• A technology roadmap tied to the commercial plan, with clear trade-offs between new features, technical debt and platform work
• Engineering rhythms in place: planning, code review standards, release process, incident handling and basic delivery metrics
• Supplier and agency arrangements reviewed, with scopes, estimates and ownership clarified
• A hiring plan for the next engineering roles, with job specifications and an interview process the CTO runs or oversees
• Where relevant, a first view on AI: which opportunities are worth pursuing, what data and controls are needed, and what it will cost to run
• A board-ready technology update that investors can understand

Month 6: measurable progress and a decision about what comes next

• Visible improvements in delivery predictability, platform reliability or security posture against the baseline set in month one
• First engineering hires made and settled, or the agency transition under way
• Technical due diligence material in good order if a raise or sale is planned
• A clear recommendation on the future shape of technology leadership: continue fractionally, increase days, hire a VP of Engineering underneath, or recruit a permanent CTO — with the fractional CTO helping to define that brief

If an engagement is not producing month-three outcomes by month three, that is worth a frank conversation. Because the arrangement is flexible, adjusting the days, the scope or the person is straightforward — and we would rather help you do that than see a mismatch drift. When the time comes to move to a full-time hire, our guide to replacing fractional executives with full-time hires covers the handover.

How a Fractional CTO Works With Your Existing Team

A fractional CTO’s effectiveness depends heavily on how they fit around the people already in the business. Thinking this through before the first day saves weeks of friction.

With the CEO and founders

The CTO needs a direct line to the CEO, a seat in leadership meetings and sight of the business plan, the budget and the investor story. Agree early how decisions will be made between you: which technology decisions the CTO can take alone, which need the CEO, and which go to the board. A short weekly or fortnightly one-to-one keeps priorities aligned between scheduled days.

With a senior developer or Head of Engineering

Where someone has been acting as the technical lead, the arrival of a fractional CTO can feel like a demotion unless it is handled well. Be open about why the role exists and what each person owns. In most successful engagements the fractional CTO owns strategy, architecture standards, board reporting and senior hiring, while the engineering lead owns day-to-day delivery and people management. Done well, the fractional CTO becomes a mentor who makes the engineering lead more capable — and sometimes prepares them to step up in time.

With an agency or offshore team

The CTO acts as the informed client. They set requirements and acceptance criteria, review the work, track spending against estimates and make sure the company owns its code, infrastructure and documentation. Tell the supplier formally that the CTO has authority to act on your behalf on technical matters, so there is no ambiguity about who signs off.

With finance, operations and the board

Technology spending is now one of the larger cost lines in many businesses, and the CTO should be able to explain it. Expect them to work with finance on cloud and software costs, with operations on the systems people use every day, and with the board on technology and cyber risk. Where the business has a fractional CFO as well, the two roles work particularly well together on budgets, business cases and due diligence.

Measuring Whether Your Fractional CTO Is Working

Because a fractional CTO is not in the building every day, it helps to agree in advance how success will be judged. Useful measures depend on the brief, but tend to include:

• Delivery: are commitments to the business being met more predictably than before? Is the time from idea to release coming down?
• Reliability and security: fewer customer-affecting incidents, faster recovery, security controls in place against an agreed baseline
• Team: key hires made and retained, engineers clear on priorities and standards, lower dependence on any single person
• Cost: cloud, tooling and supplier spending understood and under control
• Board confidence: technology reporting the board understands, and investor or acquirer questions answered without scrambling
• Decisions: the big technology choices made and documented, rather than deferred

Review these at agreed points — typically after the first month and then quarterly. A good fractional CTO will welcome the discipline and will usually propose the measures themselves.

Fractional CTO Day Rates and Cost

Fractional CTOs are paid by the day rather than by salary, and the rate depends on the CTO’s technical specialism, sector background, the seniority of the stakeholders they will deal with and the complexity of the brief. Deep-tech, AI and heavily regulated environments — fintech and payments in particular — usually command more than early-stage SaaS or digital work. The number of days per month matters as much as the rate: a CTO on four days a month and one on twelve are very different engagements, and the right level depends on what you need delivered.

We do not publish a rate card on this page, because a single range would mislead more than it helped. Our technology salary guide sets out the sourced market data, including Office for National Statistics earnings figures for technology directors and IT Jobs Watch contract data. The guide notes, for example, a contract CTO median of around £705 a day — drawn from a very small sample of advertised contract roles, so best read as an indicator for advertised delivery-focused contracts rather than a rate for board-level fractional work. On your briefing call we will give you a view of the rate that fits your specific requirement.

When comparing cost with a permanent appointment, remember that a full-time CTO comes with employer National Insurance, pension contributions, benefits, bonus, usually an equity grant, recruitment costs and a notice period, as well as the salary itself. A fractional CTO costs only the days you use. For many businesses at seed to Series A, that makes senior technology leadership affordable a year or two earlier than it otherwise would be. We can provide guidance on day rates and package structure as part of the initial briefing call.

Is there such a thing as a fractional CTO salary?

Not in the usual sense. Fractional CTOs are rarely employees; most work through their own limited company and invoice a day rate, sometimes with a monthly retainer for an agreed number of days. Some early-stage businesses add a small equity or option element to align incentives, particularly where cash is tight, but that is a negotiation rather than a market norm. If you are comparing a fractional CTO with a salaried hire, compare total annual cost on both sides rather than headline figures.

Engagement Basis: Days, Day Rate, IR35, IP and Confidentiality

Getting the engagement terms right at the start avoids most of the problems we see later. These are the points we cover with every client before a fractional CTO starts.

Days per month

Most fractional CTO engagements are set as a number of days per month rather than fixed days of the week, which gives both sides flexibility around board meetings, sprints and releases. A common pattern is heavier involvement in the first month or two while the CTO assesses the business and sets priorities, then a steadier level once the plan is running. Agree how quickly the CTO should respond between scheduled days, and how additional days will be approved if something urgent comes up.

Day rate inclusive of our fee

We quote a single, all-inclusive day rate: our fee is included in the rate you pay, not added on top, so the number you budget is the number you are invoiced. If you are weighing a fractional engagement against a permanent search, our guide to retained versus contingent executive search explains how permanent search fees are usually structured. Notice periods on fractional engagements are short by design, and we set them out clearly in the contract.

IR35 and employment status

Because most fractional CTOs work through their own limited company, the off-payroll working rules (IR35) apply. Under HMRC’s off-payroll working guidance, a medium or large client is usually responsible for deciding the worker’s employment status and issuing a status determination statement; where the client is a small company, the CTO’s own company makes that assessment. The size thresholds changed for financial years beginning on or after 6 April 2025 — a company is now medium or large if it exceeds two or more of a £15 million turnover, a £7.5 million balance sheet total or 50 employees, as set out in HMRC’s Employment Status Manual. Whoever makes the determination should check it with HMRC’s Check Employment Status for Tax (CEST) tool and keep a record of the reasoning.

A genuinely fractional CTO — working for several clients, controlling how the work is done, with no obligation to accept further work — is often outside IR35, but status depends on the actual working arrangements, not the contract label. Appointing the CTO as a statutory director changes the position and should be checked with your adviser. Our guide to IR35 rules for senior executive engagements goes into more detail, and we can talk you through the practicalities on your briefing call.

Intellectual property

This is the point most often missed. Under the Copyright, Designs and Patents Act 1988, copyright in work made by an employee in the course of employment belongs to the employer — but the author is the first owner of anything else. A fractional CTO working through their own company is not your employee, so code, architecture documents and other work they produce will not automatically belong to you. The engagement contract must include a clear written assignment of IP to your company. It should also deal with anything the CTO brings with them — their own tools, templates or code libraries — which is normally licensed to you rather than assigned. Investors check this in due diligence, and gaps are much easier to close at the start than in the middle of a funding round.

Confidentiality and conflicts

Fractional CTOs work with several businesses at once, which is part of their value. The contract should include confidentiality obligations that survive the end of the engagement, and the CTO should disclose their other clients at the outset so that any conflict — a direct competitor, or a supplier you are evaluating — can be managed. Agree access rules too: the CTO should have the system access they need to do the job, through accounts that you control and can revoke. Our guide to insurance and liability for fractional leaders covers the cover both sides should hold.

Fractional CTO Support for PE-Backed and High-Growth Businesses

Private equity firms and growth investors require technology-enabled portfolio companies to have credible CTO leadership — both to protect platform value and to ensure technology supports the commercial value creation plan. A fractional CTO provides this without the delay of a permanent search; we agree the timetable with you at briefing, and fractional appointments usually move considerably faster than permanent ones.

For PE portfolio companies, a fractional CTO typically focuses on three priorities: assessing the current technology architecture for scalability risks, strengthening the engineering team’s delivery capability and velocity, and building the technology documentation and governance that investors need to see ahead of exit. Each of these directly impacts enterprise value and is measurable within a standard PE holding period.

For VC-backed scale-ups, the fractional CTO priority is usually faster: defining the architecture that will allow the platform to scale without breaking, building the engineering culture that retains talent, and ensuring the technical decisions made at growth stage do not create insurmountable debt problems at Series B and beyond.

Investors can also use a fractional CTO across a portfolio. A technology operating partner on a part-time basis can review several companies’ platforms, spot common risks, and step into whichever business needs hands-on leadership most. If you are a fund looking at technology leadership across several companies, our private equity recruitment team can help structure that.

Technical Due Diligence: What a Fractional CTO Prepares

Technical due diligence is where a fractional CTO often pays for the whole engagement. Whether the counterparty is a venture investor, a private equity buyer or a trade acquirer, their technical advisers will work through a familiar list. A fractional CTO who has sat on the company side of that process knows what will be asked and makes sure the answers are ready before anyone opens the data room.

What investors and acquirers usually look at

• Architecture and scalability: a current architecture diagram, how the platform will cope with the growth in the business plan, and the main single points of failure
• Code quality and technical debt: an honest view of where the debt sits, what it costs, and the plan to deal with it
• Security: access controls, vulnerability management, penetration test results, incident history and any certifications such as Cyber Essentials or ISO 27001
• Data protection: what personal data is held, where, on what legal basis, and how it is protected
• Ownership of IP: written assignments from founders, employees, contractors and agencies; a record of open-source components and their licences
• Third-party dependencies: key suppliers, contracts, costs and what would happen if one of them failed
• The team: structure, key-person risk, hiring plans and retention
• Use of AI: which models and data the product relies on, how outputs are controlled, and any contractual or data restrictions
• Costs: infrastructure and tooling costs now and as the business scales

Why preparation matters

Problems found by a buyer’s advisers tend to become price reductions, warranties or conditions. The same problems found and fixed — or at least explained with a credible plan — months earlier by your own CTO rarely carry the same weight. Missing IP assignments are the classic example: easy to fix while everyone is still on good terms, awkward to fix under deadline pressure. Many businesses appoint a fractional CTO six to twelve months before a raise or sale precisely so that the technology story is ready when it is needed. Investors and portfolio companies preparing for exit can read more in our guide to how fractional executives fit into PE-backed firms.

The Fractional CTO Search Process

If you would like to prepare before the briefing call, our guides to how to hire a CTO and CTO interview questions are a useful starting point. Both apply to fractional appointments as much as permanent ones.

Sectors We Place Fractional CTOs In

• Technology, SaaS and software businesses — scaling engineering teams and platform architecture from seed through Series C and beyond
• Financial services and fintech — FCA-regulated businesses with complex technology risk, real-time processing, and compliance requirements
• PE and VC-backed portfolio companies — businesses requiring technology leadership to support value creation and exit preparation
• Healthcare and life sciences — businesses with clinical systems, data governance, regulatory technology, and MHRA or CQC requirements
• E-commerce and retail — businesses managing complex platform architecture across trading, logistics, payments, and customer data
• Media and digital businesses — content platforms, marketplaces, and digital agencies managing scale and technical complexity
• Deep tech and AI — businesses building proprietary technology requiring specialist technical leadership at board level
• Manufacturing and industrial — businesses digitalising operations, implementing IoT, or managing Industry 4.0 transformation

Fractional CTOs in regulated businesses

Technology leadership in a regulated business carries extra weight. In financial services, the FCA expects firms to understand their important business services, the technology those services depend on and how they would recover from disruption; outsourcing and cloud arrangements attract particular scrutiny, and the board needs to be able to show it understands the risks. In healthcare, clinical systems and patient data bring their own obligations. A fractional CTO in these environments needs to be fluent in the governance as well as the engineering — able to sit with compliance, risk and the board, document decisions properly and make sure that new products and suppliers are brought in with the right controls. Where a regulated firm also needs a fractional compliance officer or MLRO, we can coordinate both searches so the two roles start with a shared view of the risks.

Who we place fractional CTOs with

The businesses that ask us for a fractional CTO tend to fall into a few groups. Founder-led start-ups, often pre-seed to Series A, who need a senior technical partner and investor credibility before they can justify a full-time hire. Venture-backed scale-ups whose engineering team has outgrown its original structure. PE-backed and owner-managed companies where technology has become central to the business plan but the leadership team has no technology executive. And established businesses running a defined transformation, migration or AI programme that needs board-level ownership.

Recent fractional CTO enquiries give a flavour of the range: an AI-native fintech needing a CTO to own its model and data architecture; a media-technology venture looking for a founding CTO to take its product from concept to first release; and a treasury-management fintech wanting senior technology leadership with experience of regulated financial services. Fintech is a recurring theme — where the business is FCA-regulated, the CTO needs to work comfortably alongside compliance and operational resilience requirements, and our fintech recruitment team brings that context to the search. We do not name clients, and every brief is handled in confidence.

The Benefits of a Fractional CTO

• Board-level technology leadership at significantly lower cost than a permanent hire
• Fast access to senior capability — fractional searches typically move faster than permanent ones, and we agree the timetable with you at briefing
• Flexible engagement that scales with your technology programme and growth stage
• Cross-sector technical experience from multiple platforms, stacks, and business environments
• Objective external perspective on your technology architecture, team, and processes
• Investor-ready technology narrative and technical due diligence preparation
• Bridge leadership while a permanent CTO search is conducted

What to Look For in a Fractional CTO

The fractional CTO market includes outstanding operators and people who have simply relabelled themselves after a contract or two. Separating them takes more than a CV review. These are the qualities we assess for, and the ones we suggest you test at interview.

They have done the job at your stage

A CTO who has led a 300-person engineering organisation at a listed company may struggle in a ten-person start-up with no processes, and the reverse is equally true. Look for someone who has held technology leadership at a business of similar size, funding stage and complexity, and who can describe specific decisions they made and what happened as a result.

They can explain technology to a board

Much of a fractional CTO’s value lies in translating between engineers and the people who fund them. Ask candidates to explain a hard technical trade-off in plain English, as they would to an investor. If they cannot, they will struggle to give your board the confidence it needs.

They still understand the detail

Fractional CTOs do not need to write much code, but they do need to read it, challenge an estimate, review an architecture and know when an engineer or agency is overstating a problem. A structured technical conversation around a real issue in your business is the best test.

They manage their portfolio honestly

A good fractional CTO is clear about how many clients they have, how many days they can genuinely give you, and how they handle conflicting demands. Be cautious of anyone who promises unlimited availability on a two-day engagement.

They plan for their own replacement

The best fractional CTOs build something that outlasts them: documentation, standards, a team with clear ownership and, in time, a brief for the permanent hire. Ask how they have handed over previous engagements.

Questions to Ask Before Appointing a Fractional CTO

A short, well-prepared interview tells you far more than a long, unstructured one. These are the questions we find most revealing for fractional CTO candidates, alongside a technical conversation about a real problem in your business.

• Tell us about a business at our stage where you led technology. What did you inherit, what did you change first, and what would you do differently?
• How many clients do you work with now, how many days could you genuinely give us, and how do you handle it when two clients need you on the same day?
• Walk us through how you would spend your first month here.
• Explain the most important technical trade-off you have made recently as you would to our board.
• How have you managed an outsourced development team? How did you know whether the work was good?
• What is your view on where AI fits in a business like ours, and what would you be cautious about?
• How have you prepared a business for technical due diligence, and what did the investors focus on?
• How do you decide when a business needs a full-time CTO, and how have you handed over to one before?
• What would you need from us to succeed?

Pay attention to specifics. Strong candidates name the decisions they made, the numbers that changed and the mistakes they learned from. Weaker ones talk in generalities about “driving transformation”. References from previous fractional clients — particularly CEOs and investors — are worth taking up in every case.

Common Mistakes When Hiring a Fractional CTO

• Hiring for the technology rather than the stage. Matching a candidate’s stack to yours matters less than matching their experience to your stage and the decisions you need made.
• Too few days to make a difference. A CTO on a day or two a month can advise, but rarely lead. Be realistic about the time it takes to own a roadmap and a team.
• Vague objectives. Without agreed outcomes for the first three and six months, it is hard to know whether the engagement is working. Write them down.
• Leaving IP and access to chance. Make sure the contract assigns IP to the company and that every system the CTO uses sits in accounts you own.
• Treating the CTO as an outsider. A fractional CTO who is not invited to leadership meetings or given access to the business plan cannot do the job. Include them as you would any senior executive.
• Using the fractional CTO as a developer. Senior day rates are poor value for routine coding. Use the CTO to make your engineers and suppliers more effective.

Fractional CTO Jobs: Information for Candidates

If you are a technology leader looking for fractional CTO jobs or part-time CTO roles, we would like to hear from you. Our fractional CTO engagements come from start-ups, scale-ups, PE-backed businesses and established companies across the UK, and many are partly or fully remote. Please register with Exec Capital with a short note on your technical specialism, the stages and sectors you have worked in, and how many days a month you can offer, and see our current opportunities. We review every registration against live briefs.

What clients ask us for most often is evidence of having held real technology leadership at a comparable stage — not just senior engineering roles — along with the ability to work credibly with founders and investors, experience of managing outsourced teams, and, increasingly, practical experience of delivering AI features in production. If you have prepared a business for technical due diligence or a funding round, say so in your registration: it is one of the most common reasons clients appoint a fractional CTO.

Frequently Asked Questions

What is a fractional CTO?

A fractional CTO is a senior technology executive who works with your business on a part-time or defined-day basis — typically one to three days per week — providing board-level technical leadership without the cost or commitment of a full-time permanent appointment. The role covers technology strategy, engineering leadership, platform delivery, cybersecurity oversight, and investor-facing technical narrative.

What does the fractional CTO role involve day to day?

A mix of leadership meetings, engineering planning, architecture and code review, supplier management, hiring and board or investor reporting. Between scheduled days the CTO is usually available for urgent decisions on terms agreed at the start. The emphasis is on owning outcomes and making the existing team more effective, not on writing code.

What is the difference between a CTO and a CIO?

A CTO (Chief Technology Officer) typically focuses on product and engineering — software development, technology architecture, platform delivery, and technical innovation. A CIO (Chief Information Officer) typically focuses on internal IT — infrastructure, systems, data governance, cybersecurity, and operational technology. In smaller businesses the roles overlap or are combined. Exec Capital can advise on which profile best fits your brief and recruits across both disciplines.

How much does a fractional CTO cost in the UK?

Fractional CTOs charge a day rate, and the total cost depends on the rate and the number of days per month. Rates vary with technical specialism, sector, regulation and the complexity of the brief. Our technology salary guide sets out the sourced market data, and we will give you a view of the right rate for your requirement on the briefing call. Our quoted day rate includes our fee.

Is there a fractional CTO salary?

Generally not. Most fractional CTOs work through their own limited company and invoice a day rate or monthly retainer rather than drawing a salary. Some early-stage engagements add a small equity element by negotiation. Compare total annual cost against a permanent hire, including employer costs and equity.

How many days a month does a fractional CTO work?

It depends on what you need delivered. Lighter engagements focused on oversight and board reporting need fewer days; leading an engineering team, an agency transition or a due diligence process needs more. Many engagements start heavier in the first month or two and then settle.

How quickly can you place a fractional CTO?

Fractional appointments usually move faster than permanent searches, because candidates are used to starting new engagements and notice periods are short. We agree the timetable with you at briefing and plan the search around it. For urgent requirements — a CTO departure, an imminent fundraising technical review, or a critical platform issue — tell us at the outset and we will prioritise accordingly.

Is a fractional CTO inside or outside IR35?

It depends on the actual working arrangements, not the contract label. Medium and large clients usually make the status determination; for small clients, the CTO’s own company does. HMRC’s CEST tool can help, and appointing the CTO as a statutory director changes the position, so take advice.

Who owns the code and IP a fractional CTO produces?

Not automatically you. Because a fractional CTO is usually not an employee, the engagement contract needs a written assignment of IP to your company, with any pre-existing tools the CTO brings licensed to you. Investors check this in due diligence.

Should I hire a fractional CTO or a development agency?

They do different jobs. An agency supplies development capacity; a fractional CTO supplies independent technology leadership and accountability. Many businesses use both, with the fractional CTO overseeing the agency on the company’s behalf.

Can a fractional CTO support a fundraising process?

Yes — supporting investment readiness is one of the most common reasons businesses appoint a fractional CTO. An experienced fractional CTO prepares the technology function for investor due diligence, builds a credible technical narrative, and addresses the architecture, security, and scalability questions that technology investors will ask. Many businesses appoint a fractional CTO six to twelve months before a funding round for exactly this reason.

What technical specialisms do your fractional CTOs cover?

Our network includes fractional CTOs with backgrounds across SaaS, fintech, AI and machine learning, cloud infrastructure, e-commerce platforms, healthtech, deep tech, and enterprise software. We match technical specialism closely to your brief — a business building an AI-native product requires a different CTO profile to one running a cloud migration, and we assess candidates accordingly.

Do you also recruit interim and permanent CTOs?

Yes. Exec Capital recruits across all three models. See Interim CTO for short-notice full-time requirements and CTO Recruitment for permanent appointments.

Do you recruit fractional CTOs outside London?

Yes. Exec Capital recruits fractional CTOs across the UK — London, Manchester, Birmingham, Bristol, Leeds, Edinburgh, and all major business centres. Many fractional CTO engagements are partly or fully remote, which significantly expands the candidate pool and allows businesses to access the most technically relevant CTO regardless of geography.
