Methodology

The firms

14,499 candidate firms were assembled from public sources and each one’s website was read and classified. 6,736 are published. A firm appears only if its own site shows it invests capital into companies. Advisers, brokers, recruiters, agencies and lenders who only lend were screened out, however often they use the word “partners”.

Where the website appeared to belong to a different company than the firm name suggested, the firm was quarantined rather than published with a caveat. A caveat does not travel: the wrong association gets copied and the qualifier does not.

The crawl behind that work finished at 7,089 firms out of 7,089 and 20,037 pages read. 652 of those firms, 9.2%, returned no usable text at all: mostly single-page JavaScript applications that render nothing to a fetch, plus bot walls. Nothing was inferred to cover the hole, so a firm that could not be read is either thinner here or not published, and that 9.2% is a permanent property of the method rather than a backlog.

Portfolios

Holdings come from each fund’s own published portfolio page and from nowhere else. 62,698 holdings across 2,757 firms, with the investment year only where the fund states one. Where a holding links out, 36,797 company domains were recovered from the link the fund itself put on the page, rather than guessed from the company name.

Some portfolio pages label a holding by what it does rather than what it is called: “Medical Cannabis”, “Tender Platform”. Where the link on that row identified the company, the row was re-identified from it and the fund’s own label kept as the description, which is where 469 of the descriptions on this site come from. Where nothing identified it, the row was withdrawn. A category is not a company, and publishing it as one invents a business that does not exist.

SEC Form D

52 quarters of Form D filings, matched to 1,281 firms and 6,249 individual vehicles. A fund files one within fifteen days of its first sale, signed under penalty of perjury, which makes these the hardest numbers on the site. They are also the only numbers here that a firm cannot quietly restate on its website.

Form D covers vehicles sold in the United States. A non-US firm with a blank has usually filed nothing because it had nothing to file, and separately managed accounts, balance-sheet capital and non-US funds never appear at all. Read a Form D total as a floor, and read a blank as silence rather than as zero.

SEC Form ADV

2,340 firms are matched to a Form ADV, which gives regulatory assets under management, employee counts and the number of private funds advised. Matching is website-first: the domain the adviser filed has to be the domain the firm publishes. Names collide constantly in this industry and domains do not, so a name-only match was not accepted.

1,122 of those advisers are exempt reporting advisers, and an exempt reporting adviser reports no regulatory assets under management by regulation. The form does not ask them. Regulatory AUM therefore appears for 1,217 firms, and a blank on the rest is a question that was never put, not an answer someone declined to give. Treating those blanks as small or unknown firms is the single easiest mistake to make with this dataset.

Companies House

291 UK firms carry a company number matched against the free Companies House bulk register. Rather more than that are based in the UK: a firm trading under a name its registered entity does not use will not match, and it was left unmatched rather than attached to the nearest plausible hit.

The incorporation date on those records is the only hard founding date anywhere in this dataset. Everywhere else, “founded 1998” is a claim on a website, published here as the claim it is.

Stated criteria

4,658 firms publish something about what they will actually buy, and it was extracted by rule from their own pages rather than inferred from what similar firms do. 1,723 state where they invest, 1,176 state whether they take control or a minority stake, and 264 state a deal size in enterprise value. Every figure is kept with the page it was read from, 7,047 source URLs in total, so any of them can be traced back to the sentence that produced it.

A field is only exported once the extraction rule measures above roughly 90% precision on it, which is why several things firms commonly say are collected and not shown. Stated assets under management is dropped outright: Form ADV asks the same question under a regulator, and the regulated answer is strictly better.

Money is quoted in the currency the firm used, across 11 currencies, and is never converted. A converted figure appears on no page anywhere, which would make the source link sitting next to it a lie. The dollar sign is reserved for US dollars for the same reason: $40m beside an Australian fund means something different from $40m beside a Texan one.

Transactions

An archive of 10,204 recorded deals supplies the sector benchmarks, 1,020 acquirer pages covering 4,609 of those deals, and a buy and sell history for 555 of the funds here, including 885 recorded exits. Every row carries a deal value. Revenue and EBITDA multiples exist only where the transaction disclosed those figures, which is a minority of them, so the median deal value is the sturdier benchmark of the two.

Acquirer names arrive in the archive abbreviated. Those were expanded against the SEC company list only where exactly one listed company matched. Where two or more matched, the abbreviation was left as it was found. An expansion that picks the likelier of two public companies is a guess wearing the clothes of a fact.

What is deliberately withheld

• Individual contact details. Names, email addresses and phone numbers exist in the database behind this site. None of them are published on it, and none are for sale. The export refuses to write if one reaches a published field.
• General partner names. SEC filings name the people behind each fund, and those names are matched internally. They are not published here.
• Any score for how ready a company is to sell. “Held since 2019” is a fact the fund published about itself. “Ready to sell” is an assertion about somebody’s business that they did not invite, and it is not published, ranked or hinted at anywhere on this site.

What did not work

750 firms carried no contact route of any kind. Guessing role addresses at their own domains, the info@ and contact@ pattern, produced 14 usable addresses out of those 750. That is the technique failing, not a sample being small, and no guessed address is used anywhere, published or otherwise.

Those firms are recorded as unreachable and stay that way until one of them publishes something. A limit you can see is worth more than a figure you cannot check, which is why the failure is on the page and not in a drawer.

Known gaps

2,757 of 6,736 firms publish a portfolio at all, so the rest have thinner pages. Investment years are published by a minority of investors, and a deal size in money by fewer still. Nothing here covers a fund’s private pipeline, its unannounced deals, or anything it has decided not to say in public, which for a private firm is most of it.

Common questions

How is an investor verified?

Each firm's own website was read and classified. A firm is listed only if the site shows it invests its own or fund capital into companies. Advisories, brokers, recruiters, agencies, lenders who only lend and ordinary operating companies were screened out and are not published.

Where do the portfolio holdings come from?

From the investor's own published portfolio page, with the investment year where the investor states one. Company websites are taken from the links on that page rather than searched for. Nothing is inferred, and an investor that publishes no portfolio shows no holdings.

Why does a firm show no capital raised?

SEC Form D covers vehicles sold in the United States. 1,281 of 6,736 firms have a matched filing. For everyone else, and for most non-US firms, the field is blank because no filing exists to read, not because the firm has raised nothing. A blank is never a zero.

Why does a firm show no assets under management?

1,122 of the 2,340 advisers matched to a Form ADV are exempt reporting advisers, and an exempt reporting adviser files no regulatory assets under management at all. The form does not ask. A blank there means the question was not put to them, not that the answer is unknown or withheld.

Does a listed holding mean the company is for sale?

No. A holding is a fact published by the investor, nothing more. No company on this site is represented as being for sale, and years held are shown because they are informative, not because they imply an intention to sell.

Why are some investors missing?

Firms whose website appears to belong to a different company than the name suggests are quarantined rather than published. Firms whose site could not be reached, or carried no readable description of what they invest in, are excluded for the same reason: a wrong association is worse than a missing one.

How current is it?

Investor records were compiled in August 2026, the filing data is matched through the most recent quarter, and the transaction archive covers 2014 to 2025. Investors change strategy and realise holdings, so treat anything here as a starting point rather than a settled fact.
