Fintech71

Fintech71 was launched by brothers John M. B. O'Donnell and John C. D. O'Donnell, drawing on their experience as investors and operators. The firm's structure sits between a single-family office and a dedicated venture firm, with capital pooled from the O'Donnell family and select co-investors. Wealth originates from the O'Donnell family's prior business ventures, though specifics are not publicly detailed. The firm targets early-stage investments in fintech, enterprise software, AI/ML, cybersecurity, and climate tech — often leading rounds or participating alongside top-tier VCs. Confirmed positions include portfolio companies such as ClearGlass Analytics (per Crunchbase, 2021) and other undisclosed fintech startups. Geographically, Fintech71 focuses on the US and Europe, with office presence in both regions. Deployment pace and total AUM are not publicly disclosed. The firm maintains a lean team headquartered in Menlo Park with additional offices in San Francisco, Columbus, Dublin, Chicago, Washington, and Palo Alto. No philanthropic vehicles or adjacent operating companies have been identified in public records. Fintech71's structural differentiator is its dual-identity as a multi-family office and direct venture investor — a hybrid that allows it to commit patient, long-term capital without the constraints of traditional fund cycles. The O'Donnell brothers manage investments personally, maintaining a hands-on approach typical of family offices.
