What is a search fund? A UK primer.
A search fund is one of the most direct routes into ownership: raise a small pool of capital, spend 18–30 months looking for a single UK business to buy, then run it as CEO. This guide walks through the model, how the traditional and self-funded variants differ, and how it plays out in the UK lower mid-market.
1. The definition
A search fund is an investment vehicle formed by one or two entrepreneurs — the searchers — to raise a small amount of capital, identify a single privately-held company to acquire, close the transaction, and then step in as CEO. The concept was formalised at Stanford in 1984 and has since produced one of the highest reported IRRs of any private-equity asset class.
The mechanics are simple. Investors back the searcher's search phase in exchange for the right — but not the obligation — to fund the eventual acquisition on pre-agreed terms. The searcher does the sourcing, diligence and negotiation. On close, the same investors typically roll their search capital into the acquisition and provide the majority of the equity.
2. Traditional vs self-funded
There are two mainstream variants of the search fund model, and they carry very different risk profiles.
The searcher raises roughly £350k–£600k of search capital from 10–20 investors to cover salary, travel, diligence and legal fees for 24 months. Investors get the right to invest in the eventual acquisition. The searcher ends up with 20–30% of equity through a three-tranche vesting structure tied to close, tenure and IRR hurdles.
The searcher funds their own living costs during the search and raises acquisition capital only when they have a signed LOI. Debt (often SBA-style in the US, or asset-backed lending and government-backed schemes in the UK) plays a bigger role. The searcher keeps a much larger equity stake — commonly 50%+ — in exchange for taking on personal financial risk during the search.
3. How the economics work
Target economics for a lower mid-market deal in the UK usually look like this:
- • Enterprise value: £3m–£15m
- • EBITDA: £500k–£3m, with owner earnings that clean up cleanly
- • Entry multiple: 4x–6x EBITDA on the buy, targeting exit at 6x–9x after 5–7 years
- • Capital structure: 40–60% senior debt, the balance in equity from search fund investors
- • Searcher vesting: three tranches tied to close, time in seat and IRR hurdle (traditional model)
4. Search funds in the UK
The UK search fund ecosystem has grown quickly since the mid-2010s, with active investor groups based in London and out of the LBS and Oxford Saïd MBA networks. The mechanics translate cleanly, with a few local differences worth understanding.
- • Deal flow is dominated by owner-managed businesses with founders aged 55+ and no obvious successor.
- • Broker penetration is lower than in the US, so proprietary outreach genuinely works.
- • Debt is typically sourced from challenger banks and asset-backed lenders rather than SBA-style programmes.
- • EIS and BADR reliefs shape how sellers think about consideration, earn-outs and rollover equity.
- • Companies House data makes signal-based sourcing more tractable than in most jurisdictions.
5. Who it suits — and who it doesn't
A search fund is a good fit for operators who want to run a business but don't want to build one from zero, and who are willing to spend two years on the sourcing grind before they touch the CEO seat. It is a poor fit for anyone who wants a short path to ownership, cannot commit to a decade with one company, or expects the search itself to be intellectually glamorous. Most of the work is outreach and rejection.
6. FAQ
Most successful UK searches close between month 18 and month 30. Investor patience typically runs to 24 months of search capital with a possible extension.
No, but most institutional search fund investors are more comfortable backing searchers with an MBA or a strong operating track record. Self-funded searches are more forgiving on background.
In a traditional structure, 20–30% of the equity, vested across close, tenure and IRR. In a self-funded structure, commonly 50%+.
