Search funds, independent sponsors, holdcos and private equity platforms are usually explained one at a time. They are stages of one market: each can sell to the next.
Ask how a search fund differs from private equity and you will find plenty of answers. Ask how one turns into the other and you will find far fewer. The vehicles that buy small UK companies are usually described one at a time, as if a business met only one of them.
It can meet several. A retiring owner sells to a searcher, the searcher adds a second business, an investor buys the larger group, and a bigger fund buys that. Read that way, the market is a ladder, and every rung is a buyer that can become a seller. Pick a real deal below to see the path it took, or pick any stage, vehicle or exit to see how it works.

Most vehicles start with money and no business. A searcher raises a salary and costs from investors, or spends their own. An independent sponsor works the other way round and finds the deal before asking anyone for capital.
Capital: Search capital from investors, or the searcher’s savings. Where the value comes from: Finding an owner ready to sell before an adviser runs a process.
One trading company, often bought from a retiring owner. For a search fund this is the moment investors decide whether to fund the purchase, and the moment the searcher becomes chief executive.
Capital: Investor equity, a senior lender, often a loan from the seller. Where the value comes from: A succession solved, at the price of a small, owner-dependent business.

The second deal changes the vehicle. It needs new capital or more debt, and the owner stops running one company and starts running a small group. 16 of the 54 UK search funds and holdcos with a purchase on our record have bought a second business.
Capital: Retained cash, extra debt, or a fresh round from the same investors. Where the value comes from: Shared overheads, cross-selling, and a larger business that sells for a higher multiple.
A platform is a business built to absorb others, with a team for deals and integration. 153 of the 602 active UK buy-and-build platforms in our register are backed by private equity and 109 are owner-managed holding companies.
Capital: Institutional equity and committed acquisition debt. Where the value comes from: Integration, one brand and system, and a group large enough for bigger buyers.

A business can leave the ladder at any stage. Search fund investors expect a return one day, a fund must sell before its life ends, and a holdco can keep what it owns for good. Whoever buys starts the next climb.
Capital: The next owner’s capital, with management often reinvesting. Where the value comes from: Realised: what the earlier stages built, sold to someone who pays for scale.
One person, or a pair, sets out to buy and run one company. In a traditional search fund, investors pay for the search and get the first right to fund the deal. In a self-funded search, the searcher pays and raises capital only once a deal is found.
Capital: Search capital from investors or the searcher’s savings, then deal equity and debt. Where the value comes from: An operator with a stake, on a business too small for private equity.
A deal professional with no committed fund. They find a business, raise equity for that one deal, and usually hire someone else to run it. They earn fees and a share of the gain, then do it again.
Capital: Family offices and private investors, per deal. Where the value comes from: Deal access and judgement, without a fund’s fixed costs.
An acquisition holding company buys businesses to own them. Capital is its owners’ or a small private circle’s, and there is no date by which it must sell. Some stay in one trade, others collect unrelated businesses.
Capital: Owners, private investors and retained cash. Where the value comes from: Patience: compounding profits instead of timing a sale.
A fund usually buys control of a platform and backs it to buy smaller companies, with the sale planned from the start. It skips the search: the plan, the management and the debt come first.
Capital: A committed fund and acquisition debt. Where the value comes from: Bought small and sold large: the group is worth more than its parts.
A bigger fund buys what a smaller owner built, and often keeps the management. Water Direct and Superstruct both went this way.
Capital: The new fund. Where the value comes from: A higher multiple for a larger, cleaner business.
A group in the same trade, or a platform still buying, absorbs the business. For a small platform this is the most direct way to become a bolt-on in someone else’s story.
Capital: The buyer’s balance sheet or fund. Where the value comes from: Savings only a same-trade buyer can make.
The buyer is a person or a small team, often from inside the business. BF Mulholland went to two industry professionals, one of whom had joined it in 2017.
Capital: The buyers, usually with a lender. Where the value comes from: Continuity for staff and customers.
A holdco has no reason to sell. A fund can do a version of this too: a continuation fund moves a business it still likes into a new fund it also runs. An employee ownership trust is the UK route for owners who want neither.
Capital: Retained profits, or a new fund for existing investors. Where the value comes from: Compounding without the costs of a sale.

Start free trialAn acquisition vehicle is the company or fund set up to buy a business. In UK small-company deals it is usually a new holding company, owned by the buyer and its investors, which borrows and buys the target's shares.
What separates one vehicle from another is not the legal form. It is four questions: who puts up the money, who runs the business, how many deals are planned, and what forces a sale. Choose any two below to compare them.
| Traditional search fund | Self-funded search | Independent sponsor | Acquisition holdco | PE buy-and-build | |
|---|---|---|---|---|---|
| Who puts up the money | Investors fund the search, then the deal | The searcher funds the search; investors or lenders fund the deal | Family offices and private investors, per deal | Owners, private investors, retained cash | A committed fund |
| Who runs the business | The searcher, as chief executive | The searcher, as chief executive | Usually a hired manager | Hired managers or the owners | Management, with the fund on the board |
| Who has control | Shared: investors hold preference shares and consent rights | The searcher, in the three filed UK deals we read | Varies by deal | The owners | The fund |
| Deals planned | One, follow-ons optional | One, follow-ons optional | One at a time | Several, open-ended | Many, from the start |
| Exit clock | No fixed date, but investors expect a return | None | Set deal by deal | None | Set by the fund’s life |
| Typical first deal | One established company, owner retiring | One smaller company, often with more debt | One company, found before the money is raised | One company, often a niche trade | A platform large enough to take bolt-ons |
| Main risk | One business, one first-time chief executive | Personal cost and thin capital | Raising the money deal by deal | Spreading management too thin | Paying for integration that does not arrive |
A search fund backs one person, or a pair, to find, buy and run one company. Stanford's long-running study counts over 850 core search funds in the US and Canada since 1996. It finds that 58% go on to buy a company, typically after around 20 months of searching (Stanford, 2026).
The two forms differ in who pays for the search:
For the UK market around them, the investors, lenders and advisers, see our guide to UK search funds.
Both raise money for a deal rather than from a committed fund. The difference is what happens after completion. A searcher moves in as chief executive and stays for years. An independent sponsor usually hires someone to run the business, keeps a board seat and a share of the gain, and looks for the next deal.
So a sponsor's model repeats and a searcher's concentrates. The two meet in the middle: a searcher who has sold a business has the record to raise deal by deal, and one comparison describes exactly that route. Sponsors are the hardest vehicle to see on the register, because capital raised for one deal looks like any other investor on the filings.
An acquisition holding company, or holdco, buys businesses to keep them. Capital comes from its owners and a small private circle, and no date forces a sale. A search fund, by contrast, is built around one person and one first deal, with investors who expect a return one day.
The line is blurring. Many searchers buy through a new holding company, and some holdcos borrow the searcher's model: Euston Ventures teamed up with an acquisition entrepreneur to buy and run Hammond Chemicals. Our directory lists both, side by side.
Private equity raises a committed fund, usually buys control, and plans each sale from the start. A search fund has no committed money for the deal, usually buys a business too small for a fund, and puts its own operator in charge. The purchases are different sizes, but they are not separate markets: Soris Capital bought Water Direct as a search fund in 2022, and in December 2025 Eurazeo agreed to buy a majority of it. That is how a searcher's first deal becomes a fund's investment.
The second deal is the real change. It needs new capital or more debt, and the chief executive of one company becomes the head of a small group.
| Vehicle | With a purchase | One business | Two businesses | Three or more |
|---|---|---|---|---|
| Search funds | 32 | 26 | 4 | 2 |
| Acquisition holding companies | 22 | 12 | 5 | 5 |
Most vehicles have not made that move yet, though the record is young and many first deals are recent. Holdcos have made it more often, which fits a model built to buy repeatedly. Where our deal record dates two purchases by one buyer, the second came a median of 15 months after the first, across 7 buyers. That is a small group, so read it as direction, not as a rule.
The most active on our record is Euston Ventures, with 5 purchases, and 7 vehicles have bought three or more businesses. If you are weighing a trade to build in, our fifteen acquisition theses show which are already crowded.
Some platforms never climb the lower rungs. A fund picks a trade, backs a management team and arranges the debt before most of the deals exist. Lonsdale backed Todays Dental in 2022 with eight practices and a stated aim of more than 50, and a £20m acquisition facility followed. Family First went from four nurseries in 2019 to 100 under August Equity.
| Backer | Active platforms | Share |
|---|---|---|
| Private equity | 153 | 25.4% |
| Trading group | 131 | 21.8% |
| Owner-managed holding company | 109 | 18.1% |
| Overseas group | 69 | 11.5% |
| Not yet established | 140 | 23.3% |
Of the platforms whose backer the filings settle, private equity backs the most, 153, ahead of 131 trading groups and 109 owner-managed holding companies. It also buys faster: in the last twelve months, private equity-backed platforms made 38% of the deals, trading groups 17% and owner-managed holding companies 12%. Our State of UK buy-and-build report has the full picture, trade by trade, and our Sumer case study follows one platform deal by deal.
A business can leave the ladder at any stage, and the routes differ more than the vehicles do. Four show up on our record:
Exits among UK search funds are still few, and most of the deals are recent. The pattern to watch is the one Water Direct set: a searcher's business growing into something an institution wants.
Each rung creates a different kind of value, and that is why each can sell to the next at a profit:
The buyer at each rung is paying for what the rung below made safer. For an owner, that means the same business looks different to each buyer. For a searcher, it means the next buyer is worth thinking about on the first day.
The ladder is getting new rungs, and the boundaries between them are moving:
Vehicle counts come from our directory of UK search funds and holdcos, refreshed weekly: 79 recorded purchases across 54 vehicles. A purchase is shown only once it is on the public record, and two bought on one day count as two, so these are businesses bought, not deals as our report defines them. The gap between purchases uses the dated record of 57 deals. Platform counts come from the Autumn 2026 State of UK buy-and-build report, measured on 25 October 2026 from Companies House filings.
Each journey step links to the public source that states it. We name an ownership change only where that source exists: filings alone show that a company has a new parent, not why, and many new parents are reorganisations within the same group. The descriptions of each vehicle are our summary of how they usually work. Terms vary from deal to deal, and nothing here is investment advice.
A company or fund set up to buy a business. In UK small-company deals it is usually a new holding company owned by the buyer and its investors, which borrows and buys the shares of the target. Search funds, independent sponsors, holdcos and private equity platforms are all acquisition vehicles; they differ in who funds them, who runs the business and how long they hold it.
A search fund backs one person to find, buy and run one company. Private equity raises a committed fund, usually buys control of several companies, backs their management and plans each sale from the start. A search fund usually buys a business too small for a private equity fund, and sometimes sells to one later.
A searcher becomes chief executive of the business they buy. An independent sponsor usually does not: they find the deal, raise equity for it and hire someone to run it, then repeat. Searchers commonly raise capital for the search itself; sponsors raise only once they have a deal.
In a traditional search fund, investors pay for the search and hold the first right to fund the deal. In a self-funded search, the searcher pays their own costs and raises money only when they have a business to buy. In the three self-funded UK deals we read from filings, the searcher kept control.
No. A search fund is a way of raising money and finding a business, usually for one person who will run it. An acquisition holding company buys businesses to keep, often several, with no date by which it must sell. In practice many searchers buy through a new holding company, and some go on to behave like a holdco.
6 of the 32 UK search funds with a purchase on our record have bought a second business, and 2 have bought three or more. The change is real but uncommon, and it usually needs new capital.
