Hiring for Scale-Ups: Building the Leadership Team — A Complete UK Guide

UK scale-ups face a particularly demanding senior hiring environment. The business has usually moved past the early stage, where fractional senior leadership often produces strong outcomes, but it has not yet reached the scale, capital structure or pay envelope of an established mid-market company. Over the next couple of years the senior team often needs to grow quickly: several C-suite appointments, the move from fractional incumbents to permanent successors, and new functional leadership across commercial, operations, technology and people. Scale-ups that treat this period as a run of opportunistic hires tend to end up with a group of capable individuals who do not work as a coherent executive committee. The scale-ups that get it right treat senior team building as a deliberate programme, with the order of appointments planned alongside the funding round, the board’s expectations and the commercial plan. Earlier-stage businesses often start with a fractional CTO for a few days a week. As engineering teams grow, many companies add a VP Engineering alongside the CTO.

This guide is written for CEOs, founders, lead investors and board members at UK businesses from roughly Series B through to private equity investment or exit. It covers what makes scale-up senior hiring distinctive, the sequencing decisions, fractional-to-permanent transitions, the candidate pool, compensation and equity, and the pitfalls we see most often. If you are planning several senior appointments at once, our scale-up executive recruitment service is built for exactly that situation. If you are earlier in the journey, the startup executive hiring guide covers the first senior hires before the scale-up phase begins. Earlier-stage businesses often start with a fractional Sales Director working a few days a week.

What makes scale-up senior hiring distinctive

Five things separate scale-up senior hiring from the same work at earlier or later stages. Each of them changes how the brief should be written and how the search should be run.

• Multiple appointments running in parallel. A scale-up often needs to add several senior leaders in close succession rather than one at a time. That is a different exercise from filling a single vacancy. Each appointment changes the shape of the team the next candidate is joining, so the hires need to be planned together rather than briefed in isolation.
• Fractional-to-permanent transitions. Most scale-ups arrive at this stage with one or more fractional executives in senior roles, very often a part-time CFO who has been with the business since seed or Series A. Moving to permanent leadership is a piece of senior hiring work in its own right, and it raises a sensitive question: does the incumbent step into the permanent role, or does the business run a full search?
• Compensation catch-up. Scale-up pay frequently lags the market for the calibre of leader the business now needs. Founders used to early-stage conversations, where equity carried most of the weight and salaries were modest, have to recalibrate to what experienced senior leaders actually expect at this scale.
• Investor and board influence. Lead investors usually have firm views on senior hiring at this stage and often put forward candidates from their own networks. Handled well, that input improves the shortlist and the decision. Handled badly, it creates friction over who owns the appointment and whose candidate wins.
• Exit-readiness in later-stage scale-ups. By Series C and beyond, senior hiring starts to carry exit considerations: a CFO who can run an IPO or sale process, non-executive directors with listed-company experience, and commercial leaders with credibility in front of institutional investors. The likely exit route shapes the candidate profile for these later appointments.

What ties these together is time pressure combined with consequence. Scale-up boards rarely have the luxury of a slow, sequential process, yet each senior hire at this stage shapes the business for years. That combination is why the brief, the sequence and the assessment process matter more here than at almost any other point in a company’s life.

The sequencing decisions

Scale-up senior team building involves real choices about order. There is no single correct sequence, but four patterns recur as good practice, and the right order for any business depends on its funding position, its commercial model and where the founders’ own strengths lie.

CFO first or alongside. The CFO is usually the most urgent senior appointment at scale-up stage. The role supports fundraising, brings financial discipline, raises the quality of board reporting and, later, leads exit-readiness work. Where a fundraise is approaching, the CFO appointment often needs to be in place before the process starts rather than in the middle of it. Our CFO recruitment practice works with scaling businesses on this hire, and our sister firm FD Capital specialises in finance leadership at every stage.
Commercial leadership early. Strong commercial leadership, whether titled Chief Commercial Officer, Chief Revenue Officer or Sales Director depending on the structure, is typically a Series B priority. Revenue growth is what the business needs most for the next phase, and the appointment has the greatest effect when it is made early in that phase rather than after the commercial trajectory is already set. For businesses with recurring revenue models, a Chief Revenue Officer who owns sales, marketing and customer success as one number is often the right answer.
Operations and technology mid-cycle. COO and CTO appointments tend to come slightly later, when operating complexity and the technology estate have grown enough to need dedicated senior leadership. For many scale-ups the trigger for COO recruitment is the point at which the CEO is spending more time on internal coordination than on customers, investors and strategy. The trigger for CTO recruitment is usually a platform that has outgrown its original architecture, a founding technical lead whose strengths are in building rather than leading a larger engineering function, or an investor’s due diligence highlighting technology risk.
People leadership before headcount demands it. A Chief People Officer or HR Director is often needed earlier than founders expect. Culture, reward frameworks, management capability and employment risk all become harder to fix once headcount has grown quickly, and the cost of getting them wrong rises with every hire.

Running two or three of these appointments in parallel, rather than strictly one after another, is common in well-run scale-ups. It shortens the overall timetable, but it means the dependencies have to be worked through deliberately: who will the new COO report to, does the CRO need to be in place before the CMO brief is written, and which of these leaders will sit on the board?

Fractional-to-permanent transitions

Many UK scale-ups reach Series B with one or more fractional C-suite executives in place, most commonly the fractional CFO who has supported the business since its early rounds. As the business grows, the role usually needs more time, more continuity and a deeper commitment than a part-time arrangement can give. Three patterns recur when making the move to permanent.

Internal transition. The fractional incumbent becomes the permanent appointment. This works well where the engagement has produced a strong working relationship, the scale of the business matches what the individual wants from a full-time role, and they genuinely want the commitment. The main work is calibrating the package: moving from a day-rate or retainer arrangement to salary, bonus and an appropriate equity stake.
External search with the internal candidate considered. The business runs an external search and includes the fractional incumbent on the shortlist. This tests the incumbent against the realistic external market and gives the board confidence in the final decision. It works well when it is presented as a fair process from the outset. It works badly when the incumbent believes the outcome is a foregone conclusion and learns otherwise late in the process.
External search with a fractional handover. The business runs an external search and the fractional executive steps back once the permanent successor starts, often providing a defined handover period. Strong fractional executives frequently prefer this route because it preserves their portfolio of clients, and a well-managed handover protects continuity in areas such as board reporting, investor relations and audit.

Whichever route is chosen, it helps to agree the approach with the incumbent early and openly. A fractional leader who has been treated fairly is usually an asset in the handover and a useful reference point for the incoming executive. One who feels blindsided can make the transition far harder than it needs to be.

The candidate pool

The scale-up senior candidate pool overlaps with mid-market and private equity-backed pools, but scale-up fit brings its own considerations. Five pools recur.

Sitting senior executives at peer scale-ups. The most direct pool. Strong candidates in this group usually have options, so the proposition, the equity story and the pace of the process all matter.
Step-up candidates from larger private equity-backed businesses. Senior leaders, sometimes one level below the top seat, who are ready to lead a function at a smaller, faster-moving business. They bring scaling discipline and reporting rigour, but their fit with an earlier-stage operating rhythm needs testing.
Executives with prior exit experience. Particularly valued where the business has a defined exit horizon. Someone who has been through a sale or IPO process before knows what investors and acquirers will look for and can prepare the business accordingly.
Executives from corporate or listed companies. Candidates from established businesses bring operating depth, governance experience and process maturity. The transition to a smaller business with fewer resources and less support is real, and it needs deliberate assessment and onboarding.
UK executives returning from US scale-ups. A useful pool of UK candidates who have spent time at US venture-backed businesses and are coming home. They often bring experience of rapid scaling and larger funding rounds, but calibration is needed on UK-specific matters such as employment law, tax-advantaged share schemes and UK investor expectations.

The right pool depends on the role and the stage. A Series B business building its first proper finance function may be best served by a peer scale-up CFO. A Series D business preparing for a sale may need someone who has been through a transaction before. Being clear about which pool you are targeting, and why, is one of the most useful things a scale-up board can do before a search starts.

Assessing scale-up fit

Scale-up assessment needs to go beyond the CV. Two candidates with similar track records can perform very differently in a scaling business, depending on how they handle ambiguity, how comfortable they are building rather than inheriting, and how they work with founders and investors.

• Building versus running. Ask candidates for specific examples of functions or processes they have built from a low base, not just ones they inherited and improved.
• Pace and judgement. Scale-ups need leaders who can make sound decisions with incomplete information. Case-based discussions on real problems the business faces will tell you more than generic competency questions.
• Working with founders. Many senior hires at this stage report to a founder-CEO. Explore how candidates have handled disagreement with a founder, and how they balance challenge with support.
• Investor and board exposure. For CFO, CRO and CEO-level roles, look for evidence of presenting to boards, handling investor questions and contributing to fundraising.
• Hiring capability. Each senior hire will build their own team. Their track record of hiring and developing managers is often as important as their personal output.

Referencing should be thorough and should include people who worked for the candidate as well as those they reported to. At scale-up stage, a senior hire who cannot attract and keep good people will slow the business down regardless of their individual ability.

Compensation and equity

Scale-up senior packages typically combine a base salary set below what an established mid-market business might pay with an equity stake that can become the main economic driver over time. Three structures recur.

EMI options. Enterprise Management Incentives remain the standard tax-advantaged option scheme for qualifying UK companies. From 6 April 2026 the eligibility limits were raised significantly: the gross assets limit rose from £30 million to £120 million, the employee limit rose from 250 to 500, and the total value of options a company can have in issue rose from £3 million to £6 million, according to the government’s policy paper on the EMI changes. The maximum exercise period also increased from ten to fifteen years. In practice this means many scale-ups that would previously have outgrown EMI can now continue to use it for senior hires, which is a meaningful change for later-stage businesses.
Growth shares. For businesses that still fall outside EMI, for example because of their size, structure or trading activities, growth shares are a common alternative. They give the executive a share of value created above a hurdle set at or above current value. The tax treatment depends on the specific structure and valuation, so specialist advice is essential.
Sweet equity after private equity investment. Where the scale-up takes private equity investment, senior incentive arrangements typically move to sweet equity alongside the institutional strip. That is a different negotiation, covered in our private equity hiring guidance.

Two wider tax points affect how senior packages are put together. First, cash pay is more expensive than it was: employer Class 1 National Insurance is charged at 15% on earnings above the secondary threshold of £5,000 a year, as set out in HMRC’s rates and thresholds for employers. That makes well-structured equity more attractive relative to salary for both sides. Second, the exit tax position for founders and senior shareholders is changing. Business Asset Disposal Relief now taxes qualifying gains at 18% for disposals from 6 April 2026, according to GOV.UK guidance on Business Asset Disposal Relief. Budget 2026 also announced that the lifetime limit will fall from £1 million to £500,000 for disposals on or after 6 April 2027, with legislation to follow in the Finance Bill, as described in the government’s policy paper on the new lifetime limit. Senior candidates with significant existing holdings will often raise these points in negotiations, and boards should take professional tax advice before making offers that rely on them.

Above all, the equity conversation needs to be honest. Senior candidates at this level understand dilution, preference stacks and exit scenarios. Presenting a realistic range of outcomes, rather than a single optimistic number, builds credibility and reduces the risk of a new hire feeling misled later.

Common scale-up senior hiring pitfalls

Six patterns recur, and most of them are avoidable with some planning.

• Treating senior team building as a series of separate searches rather than a programme, so each hire is made without reference to the team it is joining.
• Handling fractional-to-permanent transitions without a clear process, leaving the incumbent unsure of their position and the board unsure of the market alternative.
• Setting pay against the business’s own history rather than the market for the leaders it now needs, which shrinks the realistic candidate pool before the search starts.
• Too little involvement from the lead investor, or too much without clear ownership, so the appointment becomes a negotiation between stakeholders rather than a decision.
• Cultural mismatch between candidates from large or private equity-backed environments and the pace and informality of a scale-up, which is often visible at interview if the right questions are asked.
• Underestimating exit-readiness for later-stage appointments, so the business finds itself rehiring a CFO or adding board members just as a transaction approaches.

A seventh, less obvious pitfall is moving too slowly. Strong senior candidates at peer scale-ups typically have choices, and a process that drifts for weeks between interview stages often loses the preferred candidate to a faster competitor.

Onboarding senior hires into a scaling business

Getting the right person through the door is only half the work. Senior hires at scale-ups often join without the induction structure a larger organisation would provide, and the first few months decide whether they succeed. A short, written plan covering the first months, agreed with the CEO and shared with the board, helps set expectations on both sides.

• Clarify decision rights. Be explicit about which decisions the new executive owns, which they share with the founder, and which still sit with the board.
• Introduce the investors early. For CFO and commercial roles in particular, early contact with the lead investor builds trust and avoids second-guessing later.
• Agree early priorities. Two or three clear objectives for the first quarter give the new hire focus and give the CEO a basis for an honest review.
• Plan the handover. Where a fractional executive is stepping back, set out exactly what is being handed over and when.
• Review at set points. Formal check-ins with the CEO and chair at agreed stages catch problems while they can still be fixed.

How Exec Capital approaches scale-up senior hiring

Exec Capital works with scale-up CEOs, founders and lead investors on senior team building as a programme of work. We handle individual senior appointments and integrated programmes covering several hires over the course of a growth phase, with the sequencing and dependencies planned alongside the funding and commercial timetable. Every search is run by our specialist team, with Adrian Lawrence FCA overseeing each mandate.

Our approach starts with the team rather than the vacancy. Before briefing a search, we look at the leadership team the business will need at the end of its growth phase, where the current gaps are, and which existing leaders, including fractional executives, fit that picture. From there we agree the order of appointments, the profile for each role and the package range the business can realistically offer. You can read more about how we run these programmes on our scale-up executive search page.

For CEOs and lead investors planning a multi-appointment programme or working through a fractional-to-permanent transition, we offer a structured initial conversation to map out the team you need and the most practical route to building it.

Frequently asked questions

When should a scale-up hire its first permanent CFO?

Usually when the finance demands outgrow a part-time arrangement: an upcoming fundraise, more complex investor reporting, a growing finance team or the early stages of exit planning. Many businesses make the move around Series B, but the trigger is the workload and risk, not the round itself.

Should our fractional CFO become the permanent CFO?

Sometimes. It works best where the relationship is strong, the individual wants a full-time role and their experience matches the next stage. Running an external search with the incumbent on the shortlist is a fair way to test that against the market.

Can we still use EMI options for senior hires as we grow?

Possibly for longer than before. From 6 April 2026 the EMI limits rose to £120 million of gross assets, 500 employees and £6 million of options in issue across the company. Other qualifying conditions still apply, so take specialist advice.

How many senior hires can we run at once?

Two or three in parallel is common and manageable, provided the dependencies between roles are planned and the CEO has time to be properly involved in each process.

How involved should our lead investor be?

Involved enough to support the decision and contribute candidates, with clear agreement on who owns the final appointment. Agreeing this at the start avoids friction later in the process.
