UK Search Funds Explained: The 2026 Guide for Owners Being Approached

Advised by Leo Meggitt, Managing Director, Mastella Advisory. Last updated August 2026.

If you own a UK business worth £5M to £50M in enterprise value, there is a fair chance a search fund entrepreneur has already emailed you. Maybe more than once. The approach is usually short, personal, direct: an individual (or a small pair) introducing themselves, referencing your industry, saying they are looking to acquire and run a single business for the long term. It reads differently from the corporate development inbound and from the PE origination email. That is intentional.

Search funds have quietly become one of the most active buyer types for UK lower mid-market businesses. This guide is for owners who want to understand what they are dealing with before deciding whether to engage. We cover what a search fund actually is, who is active in the UK market in 2026, how the economics work, what a good searcher looks like, and where the red flags sit.

What is a search fund?

A search fund is a legal and financial structure that allows an individual (or occasionally a pair) to raise a small pool of capital, spend up to two years searching for a single business to acquire, and then raise a larger pool of capital to complete the acquisition and become the CEO. The model originated at Stanford Graduate School of Business in 1984 and has since produced several hundred completed acquisitions globally. It arrived meaningfully in the UK during the 2010s and has scaled sharply since 2020.

The core proposition to an owner: a hungry, capable individual who has raised institutional backing wants to buy your business, run it personally for the next 5 to 10 years, and take on the operational load you have been carrying. The core proposition to the searcher: a chance to become CEO of an established, profitable business at a stage of their career where they otherwise could not access one.

Search funds are neither PE (which typically holds via a fund and rotates management) nor strategic acquisitions (which typically integrate). They are their own category, with their own economics and their own decision-making patterns.

The UK search fund landscape in 2026

The UK search fund market has grown from a handful of active searchers in 2015 to well over 100 individuals in active search at any given point during 2025 and 2026. Several institutional platforms now sponsor UK-based search funds, and a growing pool of independent searchers operate outside those platforms.

Institutional sponsors active in the UK:

• Novastone Capital Advisors. Swiss-headquartered, London-active, one of the most visible sponsors of UK and European search funds since ~2018. Runs a structured programme for search fund entrepreneurs, provides diligence support, and typically co-invests alongside its LP network at the acquisition stage.
• Broadleaf Capital. UK-focused sponsor, active in origination and support for UK searchers, with a portfolio of completed UK acquisitions across services and industrial niches.
• First Search. London-based, focused on early-career entrepreneurs and typically funding search phase directly. Has completed multiple UK acquisitions.
• Cambria Group / affiliated Cambria structures. Longer-established permanent capital vehicle with search-fund-adjacent activity in the UK lower mid-market, though not a pure search fund sponsor in the traditional sense.
• Independent searchers. A material and growing portion of UK search fund activity happens outside institutional sponsors. Individuals raise a small "search stipend" from a personally-assembled group of 15 to 25 LPs (frequently HNW individuals, family offices, and former search fund CEOs), then raise the acquisition capital from a similar or overlapping group once they have found a target. Independent searchers are harder to categorise as a buyer type because each one runs their own capital and their own criteria.

Beyond these named participants, an expanding cohort of UK LPs (family offices, HNW individuals with prior operational or PE experience, and specialist search fund funds-of-funds such as those managed by Relay Investments, Search Fund Partners, and others based primarily in the US but active in UK deals) provides the capital that makes the model work.

Deal structures: self-funded, traditional, and sponsored searches

Not all searchers are the same. The economics and behaviour of a searcher who has raised through an institutional sponsor are meaningfully different from a self-funded individual working alone. As an owner being approached, understanding which type you are dealing with changes what to expect.

The traditional search fund

The traditional model, as pioneered at Stanford, involves the searcher raising a "search stipend" (typically £350,000 to £600,000 in current UK terms) from a group of 15 to 25 LPs. This funds the searcher's salary and operating costs for 18 to 24 months. When the searcher identifies a target and negotiates a deal, the same LPs (usually) have the right of first refusal on the acquisition capital. Additional acquisition capital is raised from those LPs and from a wider network. LPs who funded the search get a "step-up" (see economics below) as reward for the risk they took during the search phase.

The sponsored search fund

An institutional sponsor (Novastone, Broadleaf, First Search, and others) provides the search stipend directly, plus significant infrastructure: legal and financial diligence support, deal structuring assistance, LP network access, and a co-investment commitment at the acquisition stage. In exchange, the sponsor typically retains a larger economic interest and a board seat post-acquisition. Sponsored searches tend to complete faster than self-funded searches (the sponsor has done this before, LPs are pre-wired) but the CEO ends up with a smaller equity stake.

The self-funded search

The searcher funds their own living costs during search (from personal savings or a working spouse) and does not raise a search stipend. When they find a target, they raise the acquisition capital directly, typically from HNW individuals, family offices, and small institutions, without the step-up mechanism that applies to traditional searches. Self-funded searchers are more common in the UK than the pure textbook Stanford model. They tend to move slower, negotiate harder on price (their personal capital is genuinely at stake), and structure deals more creatively.

For an owner, the practical implication is: ask the searcher which model they are running, who their LPs or sponsor are, and how much acquisition capital they have committed or credibly close to committed before you spend time in exclusivity.

Sponsor economics: step-up, common carry, and CEO equity

Search fund economics look opaque from the outside but resolve into three components: the step-up on search capital, the common carry the CEO earns over time, and the equity split between CEO, sponsor and LPs post-acquisition. These matter to you as an owner only insofar as they shape the searcher's behaviour and their capital availability.

The step-up

LPs who funded the search phase typically receive a 150% step-up on their search capital when it converts to equity in the acquisition. In practical terms: £500,000 contributed during search converts to £750,000 of preferred equity in the operating company at acquisition. This is compensation for the risk that the searcher would never find a deal and the LPs would lose their money entirely. In a sponsored search, the sponsor sits in this LP position and receives the step-up.

Common carry (the CEO earn-in)

The CEO earns their equity through vested tranches. The industry-standard structure is 25% common equity in three roughly equal tranches: 8.33% vests on completion of the acquisition (the "acquisition tranche"); 8.33% vests over time (typically 4 to 5 years of service); and 8.33% vests only if the deal returns above a defined IRR hurdle (typically 20 to 25% net IRR to LPs) on eventual exit. This structure aligns the CEO with the LPs by making the top tranche of equity contingent on a genuinely successful outcome.

Equity split at acquisition

After the step-up is applied and the acquisition capital is invested, LPs (or the sponsor plus LPs) typically hold 70 to 80% of the common equity, with the CEO holding the remainder (subject to vesting). Preferred equity and any senior debt sit above the common. Owners taking rollover equity into the acquisition vehicle sit alongside the LPs in the preferred stack, typically on terms negotiated at the deal, which we cover in a separate rollover equity article.

How search funds source deals

Most search fund outreach is direct: personal emails and LinkedIn messages, sometimes phone calls, from the searcher (or the searcher's analyst) to owners identified through a bottom-up screening process. Institutional sponsors provide list infrastructure and sometimes make warm introductions, but the actual outreach is almost always from the individual who intends to become CEO. This is by design. Owners in the £5M to £50M EV range typically respond better to a personal approach from a named individual than to a generic corporate development email.

Talk to us

If a search fund searcher has approached you and you want an independent view on whether their offer is fair and whether their capital is real, book a 45-minute confidential conversation. We work with UK owners on structured processes that test any inbound offer against the wider buyer pool.

What owners should ask a searcher who has approached them

The single most useful thing an owner can do before spending real time with a searcher is ask a small number of specific questions. The answers tell you whether you are dealing with a serious buyer or an aspirational one.

1. Are you self-funded, sponsored, or traditional? If sponsored, who is your sponsor and what have they backed before? If traditional, how many LPs have committed to your search and to acquisition capital?
2. How much acquisition capital do you have committed or soft-circled? A credible searcher will give a specific range. An evasive answer usually means the capital is not yet real.
3. What is your target size and criteria, in writing? Serious searchers have a written thesis they can share. If they cannot, they may be casting a wide net rather than pursuing a defined strategy.
4. How many owners are you actively in conversation with, at what stage each? This tells you whether you are one of many early-stage conversations or one of a small number of near-term priorities.
5. What is your background, and what specifically prepared you to run a business in my sector? The strongest searchers have a specific reason to be interested in your sector, beyond that it fits the size criteria.
6. What is the debt structure you are planning? Serious searchers can articulate the senior debt sizing they expect, from which lender, and on what covenants.
7. What is your timeline to a signed LOI if we decide to progress? The answer tells you whether they are ready to move or still in exploratory mode.

Red flags

Several patterns should make an owner cautious about progressing with a specific searcher:

• Vague on the capital stack. A searcher who cannot articulate their acquisition capital plan in specific numbers is not ready to transact.
• No named sponsor or LPs. Traditional searchers should be able to name their LPs (at least in aggregate terms) or their sponsor by name. Anyone who is opaque on where the money comes from is either early in their raise or not credible.
• Insistence on early exclusivity. A searcher pushing for exclusivity before they have shared substantive diligence on themselves and their capital is trying to lock you out of alternatives. Push back.
• Unrealistic multiples in initial conversation. A searcher who offers a very high multiple as a "conversation starter" and then chips away in diligence has followed a well-worn playbook. Treat headline offers as directional only until they are backed by committed capital.
• Rushed timeline. Search fund deals typically take 6 to 12 months from first serious conversation to completion. A searcher promising completion in 8 weeks is either exceptional or overpromising.
• Reluctance to introduce their LPs or sponsor. Serious searchers will make their sponsor or a lead LP available for a call with the seller during exclusivity. Reluctance is a signal.

Search funds vs private equity vs strategic buyers

The three categories behave differently in ways that matter to owners deciding between them. In brief:

• Search funds typically pay slightly below trade acquirer multiples but often above pure PE multiples for the same asset. They offer the strongest cultural continuity (a single individual running the business long-term) and the most personal transition. They carry meaningful execution risk (the CEO has not run a business at this scale before).
• Private equity typically pays market multiples with the ability to stretch for platform assets, offers professional integration and value-creation infrastructure, and is generally organised around a 4 to 7 year hold and exit. Cultural continuity depends heavily on the specific fund and the founder's post-sale role.
• Strategic acquirers typically pay the highest headline multiples where genuine synergies exist, but integrate the business into an existing operating structure. Cultural continuity is often the weakest of the three routes, but the immediate certainty and cash proportion are often the strongest.

We compare the three routes in more depth in a dedicated article: Search Fund vs Private Equity vs Strategic Buyer.

Where search funds fit in a structured process

Owners who receive a search fund approach have three options. The first is to engage bilaterally with the individual searcher and negotiate directly, which works well for owners with strong personal chemistry with the searcher and low interest in testing the wider market. The second is to decline politely and move on, which is the right answer for owners not yet ready to sell. The third is to use the inbound approach as a prompt to run a structured competitive process across the wider buyer pool, which tests the search fund offer against strategic acquirers, PE, and other searchers.

The third route is what we typically advise for UK owners in the £5M to £50M enterprise value range. A single bilateral negotiation, even with an excellent searcher, rarely produces the same total outcome as a competitive process. The search fund often remains the eventual buyer because the fit is genuinely right, but the terms sit at a materially better place than they would have in isolation.

The mechanics of running that competitive process, and the sector-specific buyer pools we approach, sit under our M&A advisor service and are illustrated across our sector pages. Owners considering an exit in the next 12 to 24 months should read our exit planning guide before running any process, bilateral or competitive.

Conclusion

Search funds have become a real feature of the UK lower mid-market buyer landscape and are worth taking seriously when a searcher approaches you. The model attracts genuinely capable individuals who intend to run the business long-term, backed by institutional or family capital that is real. But the range of quality across searchers is wide, the economics take some understanding, and the temptation to negotiate bilaterally when a credible individual approaches you often costs owners meaningful value they would have captured in a wider process.

Understand the model. Ask the right questions. Test the market before you commit. If you want an independent view on a specific inbound approach or on how to structure a wider process, book a confidential conversation. Forty-five minutes, no obligation, and you will leave with a clearer picture of what your options actually look like.
