100-Day Plan Executive Placement

The 100-day plan is where the investment thesis first meets the reality of running the business. Every management change, operational initiative and strategic decision taken in the first hundred days after a deal completes sets the direction of the hold period. The executives appointed into the business at or shortly after completion are not simply filling vacancies — they are the people who will deliver the 100-day plan itself. This page sets out what the board, the investor and the incoming executive need to agree before day one, what the executive should do across the first thirty, sixty and ninety days, and how Exec Capital places leaders into that window through our executive search practice.

If you are still deciding who to hire and how to run the selection process, our companion guide on what PE firms get wrong in portfolio company hiring in the first 100 days covers the hiring decision. This page picks up where that one ends: the executive has been chosen, the deal has closed, and the clock is running.

100-Day Plan Executive Placement

Exec Capital places senior executives whose first job is to execute the post-deal plan in private equity-backed and newly acquired businesses across the UK mid-market. A 100-day plan placement covers the window between completion and the point at which the business has operating momentum under its new ownership — usually marked by the first full quarterly board review. The appointment might be a new CEO or CFO installed at completion, a COO brought in to run an operational programme the incumbent team cannot deliver, or a specialist hired against a single value creation initiative.

What makes these placements different from an ordinary senior hire is that the role is defined as much by a timetable as by a job description. The investor has a thesis, a set of early milestones and a reporting rhythm it expects to see from the first month. The executive is judged against that timetable from the day they start. A candidate who would succeed over a two-year horizon in a stable business may still struggle when asked to produce a credible view of the business in four weeks, with incomplete information and a board watching more closely than it will at any other point in the hold.

Most of these appointments sit within our wider work on portfolio company executive recruitment and private equity recruitment. The 100-day plan placement is the subset where timing, a pre-agreed mandate and the investor relationship matter most.

What the 100-day plan demands from incoming executives

The first hundred days of a new ownership period are the most demanding of the investment cycle, operationally and organisationally. The business is adjusting to new owners, new governance, new reporting requirements and often new management. The investor is paying closer attention than at any later point. The existing management team is reading the new owner’s intentions and wondering about the security of their own roles. Key customers and suppliers are watching for signals about direction. Against that backdrop, the 100-day plan — the structured programme of assessment, decisions and early action agreed between the investor and the leadership team — has to be delivered.

Executives placed into this environment have to do four things at once that many senior candidates have not had to combine before:

• Assess the business quickly and accurately. Form a view of what is actually true about trading, cash, the team and the opportunities, working from incomplete information and from an investment case that was, by its nature, written to support a purchase.
• Build trust fast. Establish working relationships with the existing management team, the investor board and key external stakeholders within weeks rather than months.
• Start acting within the first thirty days. Begin the specific operational, financial or commercial initiatives the plan requires without waiting for the complete picture the first quarter’s management accounts will eventually provide.
• Report credibly. Give the board information it can rely on, at the frequency and level of transparency the early hold period demands, including the bad news.

What the board, investor and executive should agree before day one

Most problems in the first hundred days trace back to things that were never written down. Before the executive starts, the chair, the investor deal team (and operating partner, where there is one) and the incoming executive should agree in writing:

• The three to five outcomes that define success at day 100, expressed as things that will be visibly done or decided, not as activity.
• Decision rights. Which decisions the executive can take alone, which need the chair, and which are reserved to the investor under the shareholder agreement. Reserved matters lists are often long, and an executive who discovers them in week three loses time and credibility.
• The reporting rhythm. The format and timing of the monthly board pack, any weekly flash reporting, and what the investor will want to see at each board meeting in the first quarter.
• The position on the existing team. Whether the investor has already formed views on individuals, and how much latitude the new executive has to make their own assessment before changes are made.
• Resources. Budget for advisers, interim support and any early hires the plan assumes, so the executive is not negotiating for resource while trying to deliver.

Statutory directors should also be clear on what the role carries legally. A director’s duty to promote the success of the company under section 172 of the Companies Act 2006 is owed to the company, not to the investor that appointed them, and a good 100-day plan respects that. GOV.UK’s guidance on being a company director is a useful short reminder for executives taking their first board seat in a portfolio company.

Executive functions placed in the 100-day window

CEO — where the management structure agreed at completion requires a new chief executive. The 100-day CEO has to combine rapid assessment of the business with establishing their leadership and earning early credibility with the investor board. They own the overall plan, set the tone for the existing team and decide, with the chair, where the early effort goes. Our portfolio company CEO guide covers how that role differs from running an owner-managed or listed business.

CFO — the most commonly required 100-day appointment after the CEO. The incoming CFO typically owns the financial integration, the first monthly board pack under the new owner, covenant reporting to the lenders, cash forecasting and the upgrade to financial controls that most acquisitions need. Their contribution is visible and measurable from the first month-end.

COO — where the value creation plan requires operational intervention the incumbent team cannot deliver. The 100-day COO runs the operational diagnostic, identifies the main improvement levers and starts the improvement programme within the first quarter.

Value creation specialists — functional executives placed against a specific initiative in the plan: a commercial lead to assess and restructure the sales function, a technology leader to run the systems diagnostic, or a people director to run the management assessment and retention programme. Our value creation executive recruitment page explains how those briefs are scoped.

Not every 100-day requirement needs a permanent appointment. Where the plan calls for a defined piece of work — a finance function rebuild, a carve-out, a systems migration — an interim executive on a fixed term can deliver it while the permanent search runs in parallel. Where an interim is engaged through a personal service company, the hiring business will usually need to make an employment status decision: for medium and large private sector clients, HMRC’s guidance on off-payroll working (IR35) places that responsibility on the client.

Speed of deployment

The 100-day window does not sit comfortably with a conventional retained search timetable. A CEO appointment that runs for three months from brief to start date uses up most of the plan period before the new executive has had their first day, and notice periods for senior people can add months more. The practical answer is to start the search before completion wherever the deal team can do so confidentially, and to plan for the gap if the right person cannot start on day one.

Our approach to 100-day placements shortens the time from brief to start without lowering the bar. That comes from three things: an established network of executives who have worked in PE-backed businesses and understand the post-deal environment; a clear brief agreed with the investor and chair at the outset, so the search does not change direction halfway through; and running investor conversations, referencing and offer preparation in parallel rather than one after another. How quickly a shortlist can be presented depends on the role, the location and the market at the time, and we will give you a realistic view when we take the brief.

Managing the gap before the executive starts

If the chosen executive is serving a notice period, the business should not stand still. Options include an interim covering the role until the permanent appointee arrives, the incoming executive joining board meetings or key planning sessions before their formal start (subject to their current employer’s agreement), and the chair or operating partner taking temporary ownership of specific workstreams. Whatever is chosen, the incoming executive should be consulted on any decision that will bind them once they start.

There are also administrative steps that are easy to overlook when a deal is closing. Since 18 November 2025, new directors have had to verify their identity with Companies House before they can be appointed, so build that into the completion timetable rather than discovering it on the day.

The 100-day plan assessment framework

Exec Capital uses the 100-day plan itself as a central assessment tool in the placement process. Candidates are asked to set out their specific approach to the first thirty, sixty and ninety days of the mandate: what they would assess, what they would decide, what they would start and what they would report to the board at each point. This separates candidates who genuinely understand the post-deal environment from those presenting a generic onboarding framework.

The exercise is useful for the investor and chair as well as for us. It tests the candidate’s actual understanding of the situation rather than their ability to present a career history well, and it gives the eventual appointee a draft plan they can refine with the board before they start. The same structure then becomes the backbone of the executive’s first hundred days.

Days 1 to 30: listen, verify and stabilise

The first month is about establishing what is true. The executive should meet every member of the senior team individually, the largest customers and suppliers, the lenders where relevant, and the people in the business who actually know how things work. They should test the key assumptions in the investment case against what they find — trading, margin, cash conversion, pipeline — and flag any material differences to the chair early. A short list of quick, visible decisions (often removing an obvious blocker the team has complained about for years) builds credibility, but major structural changes in the first month are usually premature.

For a CFO, this month usually includes delivering the first month-end under the new owner, confirming covenant definitions and reporting dates with the lenders, and producing a short-term cash forecast the board can rely on.

Days 31 to 60: decide and commit

By the second month the executive should be able to present their assessment to the board: what is in line with the investment case, what is better, what is worse, and what they propose to do about it. This is when decisions about the management team are typically made, priorities for the rest of the year are fixed and the initiatives in the value creation plan are given owners, budgets and dates. The board should expect clear recommendations, not a list of options.

Days 61 to 100: deliver and embed

The final phase is about showing progress against the agreed outcomes and putting in place the routines that will carry the business through the rest of the hold: the management meeting cadence, the KPI set, the board pack format and the accountability for each value creation workstream. By day 100 the investor should be able to see that the plan is under way, that the numbers are reliable and that the leadership team is the one it will back for the next phase. Our executive onboarding guide covers the wider onboarding process that sits around these milestones.

Integration after an acquisition

Where the deal is an add-on acquisition rather than a new platform investment, the first hundred days also involve bringing two leadership teams together. Decisions about who leads which function, how the combined business reports and how culture and incentives are aligned need to be made early, and communicated clearly. Our post-acquisition senior team integration guide goes into this in more detail.

A 100-day plan placement rarely sits on its own. The same deal often requires changes at board level, an interim to bridge a gap, or a further hire once the first assessment is complete. Exec Capital covers permanent, interim and fractional appointments across the C-suite and the board, so the investor can work with one search partner throughout the early hold period. Our PE executive hiring guide sets out how investors typically approach leadership hiring across the whole investment cycle, from pre-completion to exit, and the related service pages are listed at the foot of this page.

Working with Exec Capital on 100-day plan placements

Every 100-day plan placement is run by our specialist team, with Adrian Lawrence FCA overseeing each mandate. Adrian is a Chartered Accountant and former listed-company Finance Director who has been placed into a private equity-backed management buy-out himself, so the firm understands from the inside what an investor board expects in the first months after completion.

A typical engagement starts with a briefing call with the deal team or chair to understand the investment thesis, the 100-day plan and the specific gap the appointment has to fill. We then agree the brief, the profile and the timetable in writing, and run the search against that brief, using the 100-day assessment framework at interview. Candidates are referenced thoroughly, and we support the offer, notice and pre-start period so the executive arrives ready to deliver. Where governance matters, we also draw on the expectations set by the UK Corporate Governance Code, which many investors use as a reference point for portfolio company boards even though it applies formally only to certain listed companies.

The aim is to place the right executive into the 100-day window quickly enough to matter — not a compromise candidate found fast, but the right candidate found at the pace the deal requires. To discuss a requirement, see our executive search service or call 0203 834 9616.

Frequently asked questions

What is a 100-day plan for a newly placed executive?

It is a written plan, agreed between the executive, the chair and the investor, setting out what the executive will assess, decide and deliver in their first hundred days, and how progress will be reported to the board. In a PE-backed business it is tied directly to the investment case and the value creation plan.

Who should write the 100-day plan?

The investor usually sets the outcomes it needs, but the incoming executive should own the plan for how to get there. A plan written entirely by the deal team and handed over on day one tends to lack the executive’s commitment; one written without investor input risks missing what the board will judge them on.

Should we hire an interim while the permanent executive works their notice?

Often, yes, if the role is critical to the plan — most commonly the CFO. An interim can deliver the first month-ends, lender reporting and controls work so the permanent appointee inherits a stable function. Make sure the interim and the incoming executive are introduced early and agree a handover.

How soon should the new executive make changes to the management team?

Usually after an initial assessment in the first month or so, unless there is an obvious problem that cannot wait. Moving too quickly risks losing people whose value was not visible at first; moving too slowly lets uncertainty damage morale and performance.
