Private Equity Firms in Washington State

7 firms profiled · Updated October 28, 2026

Washington's private equity firms are concentrated in Seattle, and they reflect the region's mix of healthcare, industrial and consumer businesses. Most of them invest across the country, but several know the Pacific Northwest especially well.

Healthcare is a strong theme. One of the larger firms here invests only in healthcare, and others back healthcare services alongside manufacturing, distribution and logistics companies.

Owners in the trades and in environmental services will find interest too. Seattle firms have backed roofing, construction and environmental services businesses, and an independent sponsor here builds technology services companies, including managed IT providers and an electronics recycler.

The range of buyer types is unusually wide for one city. Alongside traditional funds, Washington is home to an eighth-generation family enterprise that invests its own capital, a firm that combines debt and control equity in a single package, and an investor that backs search fund entrepreneurs who each buy one company and run it.

Most firms here look for companies with roughly $2 million to $25 million of EBITDA. A buyer close to home can visit the business easily, but every firm here buys outside the state, and many active buyers of Washington companies are based elsewhere. The better questions are whether a firm has bought businesses like yours, at your size, and what happened to the founders and managers 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 Washington firms are active in their industry.

Greymont is paid by buyers, never by owners. Greymont can help Washington owners compare these firms with national buyers active in the Pacific Northwest and find the right fit.
