About PE Firm Index

PE Firm Index is a public-source research hub for mapping private equity firms, portfolio companies, sectors, and market signals across the private capital ecosystem. The platform is designed for investors, operators, portfolio executives, advisors, and professionals who need a structured view of the PE landscape without relying on opaque or paywalled data alone.

Coverage focuses on mid-market and lower-middle-market private equity, growth equity, and buyout activity — particularly in B2B software, healthcare, industrials, business services, financial services, and professional services.
