McNamara Family Investments

McNamara Family Investments is a Toronto-based family office angel fund established in 2010 by Adam McNamara. It backs early-stage deep-tech founders in Canada — and occasionally the US — at the angel and pre-seed stages, with a DARPA-style risk tolerance focused on hard science and important problems over short fund-cycle returns. The firm writes checks of up to $250,000 with no board seat required and investment decisions delivered within days of a single meeting. It also invests as an LP in specialist venture funds with deep sector expertise, including Fifty Years, MCJ Collective, and Uncorrelated. Its sector focus spans nuclear energy, biotech, materials, space, climate, AI, defense, and robotics. Notable portfolio companies include Aalo Atomics, Varda Space, Planetary Technologies, E-Zinc, GaN Systems (acquired by Infineon), and Valence Labs (acquired by Recursion Pharmaceuticals). Beyond deep tech, the firm has backed prominent software companies, including Mercury, Superhuman (acquired by Grammarly), Ada, Fullscript, and Voiceflow, among others. Follow-on investors in its portfolio include Andreessen Horowitz, Founders Fund, Khosla Ventures, and Y Combinator.
