Background
HarbourVest led 9fin's $170m Series C in 2026, the round that took the AI-powered debt intelligence platform to unicorn status with a valuation above $1bn. HarbourVest's participation as lead investor is notable: as a fund of funds, it more typically backs other VC and PE managers rather than leading direct growth Rounds. The 9fin investment reflects a broader push into direct company exposure by large private markets managers seeking concentrated positions in high-growth fintech.
Founded in 1982 as Hancock Venture Partners (a subsidiary of John Hancock Insurance), HarbourVest became independent and is now headquartered in Boston, Massachusetts. It is one of the largest private equity fund of funds managers in the world, with over $150bn in assets under management as of December 2025. The firm has offices in Beijing, Bogota, Seoul, Tel Aviv, Tokyo, Toronto, London, Singapore, and Hong Kong, making it one of the most geographically distributed alternative asset managers. It invests across buyouts, venture capital, private debt, infrastructure, and real assets.
In February 2026 HarbourVest closed its inaugural Private Equity Continuation Solutions (PECS) Fund at $1.1bn, focused on single-asset continuation transactions, signalling a broader strategic expansion beyond traditional fund-of-funds mandates. Its London presence makes it a natural lead for UK-headquartered growth companies seeking US institutional credibility alongside European and Asian co-investors.
