Background
Jason Thorn is a Managing Director at Permira, based in the firm's Menlo Park, California office, where he focuses on investments in the Technology sector. Per Permira's team page, he has worked on transactions including BioCatch, Engine, Housecall Pro, Salsify, Seismic, and Versaterm. He holds a B.A. in Business Administration and Economics from Rhodes College.
Before Permira, Thorn spent roughly two years (joining in 2019) as a Vice President at Mainsail Partners, the San Francisco–based growth equity firm that invests in growing, often bootstrapped B2B software companies. In that role he was responsible for originating, executing, and supporting software investments. This Mainsail tenure is the source of the contact details in the original stub — note that the "Angel Investors / Seed Round" labels in that stub are inaccurate: both Mainsail and Permira are growth-equity/private-equity firms, not angel/seed investors.
Prior to Mainsail, Thorn spent about four years at The Riverside Company in Cleveland, OH, as an Assistant Vice President, executing and supporting middle-market investments. During that time he served as an active Board Director of Omnigo Software, CertaSite, LILLEbaby, and The Marena Group. Earlier in his career he worked in investment banking / private equity, including roles associated with Cyprium Partners, Raymond James, and Wells Fargo's Technology Group.
Investment Thesis & Focus
- Invests in software and technology companies — his consistent thread across Riverside, Mainsail, and Permira.
- At Mainsail, the mandate was growth equity for growing, frequently bootstrapped/founder-led B2B software companies ("Growth Equity for Bootstrapped Software Companies"), spanning origination, execution, and hands-on portfolio support.
- At Permira, he operates on the firm's global technology strategy, working on larger growth-equity and buyout transactions in established software businesses.
- Given his background, he is oriented toward capital-efficient, revenue-generating software companies rather than pre-product or pre-revenue seed startups.
