Background
Mike Walsh is a General Partner at Green Visor Capital, a San Francisco–based venture firm founded in 2013 that invests exclusively in early-stage FinTech companies. He brings a financial-services investing pedigree to the fund, with more than a decade of institutional investing experience prior to venture capital. He works alongside founding Managing Partner Simon Yoo, Chairman Joe Saunders (former CEO of Visa), and fellow General Partner Lou Forster on the firm's partner team.
Before Green Visor, Walsh co-founded and was a partner of Lusman Capital Management, a hedge fund capitalized with approximately $400 million, where he invested across multiple asset classes and geographies. Earlier in his career he spent three years at Citigroup in the Investment Banking Division, where he worked on raising equity and debt capital for financial institutions — experience that maps directly onto Green Visor's FinTech thesis.
Walsh holds a Bachelor of Arts in Economics from Harvard College. As part of his role at Green Visor, he has taken board and board-observer positions across the firm's portfolio, including companies such as Imandra, Polygon.io, Cion Digital, Pie Systems, Dharma, and DataFox (acquired by Oracle in 2018).
Investment Thesis & Focus
- Exclusively FinTech. Green Visor states: *"Fintech is our exclusive investment focus. We seek to invest in extraordinary founders that are solving the biggest unsolved problems in financial services through innovative use of technology."*
- Stage: Early stage — primarily seed and Series A — and the firm is willing to lead financing rounds rather than only follow.
- Founder-first, mission-driven: Emphasis on backing "extraordinary founders," with a stated priority on social responsibility and improving access to financial services.
- Sector depth as edge: The partners lean on a deep financial-services network and operating/investing experience (e.g., Walsh's hedge-fund and investment-banking background, Joe Saunders' Visa leadership) to add value at the partner level.
- Breadth within FinTech: Portfolio spans payments, market infrastructure/trading, market data, crypto/stablecoin compliance, procurement/payments automation, and financial education.
