A stated mandate is a firm’s description of itself and was true of the page on the day it was read; firms widen and narrow what they will look at without updating the site. Audax Private Equity states that it takes majority or outright ownership. The team figure counts the people the firm shows on one team page, so it is a floor rather than a headcount: firms that split their team across tabs or load it in pages will read low. Nothing here is a commitment by Audax Private Equity to consider any particular business, and nothing on this page is represented as being for sale.
SEC filings
What Audax Private Equity has raised
From this firm's own Form D filings. A fund files one within fifteen days of its first sale, under penalty of perjury, which makes these the hardest numbers on the page.
| Vehicles filed | 13 |
| Total capital raised | $5.6bn |
| Largest single vehicle | $3.3bn |
| Filing history | 2015 to 2025 |
| Smallest accepted commitment | None stated |
| Filed from | MASSACHUSETTS |
Form D covers US-domiciled vehicles raised from accredited investors. It will not capture a fund raised outside the United States, separately managed accounts, or capital deployed off balance sheet, so treat these as a floor rather than a total.
