Private Equity Firms in Missouri

9 firms profiled · Updated October 28, 2026

Most of Missouri's private equity firms are based in St. Louis and its Clayton business district, with others in Kansas City and Columbia. Together they cover a broad mix: manufacturing and distribution, business and home services, healthcare, software and consumer companies.

Missouri stands out for long-term capital. Firms here include a family-owned company that invests its own permanent capital, a firm that raises 30-year funds so it can hold businesses far longer than a typical fund, and family offices that buy controlling stakes. For owners who care about legacy and continuity, those structures are worth understanding.

Traditional funds are active too. St. Louis firms have built platforms in IT services, landscaping and commercial services, pest control, healthcare and software, usually through steady add-on acquisitions.

Most look for companies with roughly $2 million to $25 million of EBITDA, though a few go up to $50 million. One firm is also licensed as a Small Business Investment Company and can provide subordinated debt alongside equity, which suits owners who want growth capital without giving up control.

A buyer in the same state can visit often and already knows the local lenders, accountants and attorneys. Even so, every firm here buys outside Missouri, and many active buyers of Missouri companies are based elsewhere. The better questions are whether a firm has bought businesses like yours, at your size, and how the founders and managers fared after closing.

The profiles below are built to answer those questions. Each one lists the firm's announced deals from the last two years, with dates and links to the source, along with its stated size range and current portfolio, so an owner can quickly see which Missouri firms are active in their industry.

Greymont is paid by buyers, never by owners. Greymont can help Missouri owners compare these firms with national buyers active in the central US and find the right fit.
