Mark Trevitt is the Founder and Managing Partner of Defined, a thesis-first venture capital firm in Vancouver, British Columbia, after spending nearly a decade investing in AI at BDC Capital starting in 2014. His investment thesis targets early-stage startups shaping the “AI frontier,” focusing on seed to Series A rounds in developer tools, cloud infrastructure, data services, AI, and generative AI across North America. Defined typically invests initial checks between $100,000 and $500,000, prioritizing seed-stage deals while retaining capacity for pre-seed or Series A entries. Notable portfolio companies include Cognota, which received a $5M Series A in September 2023, Spark (Series A, $5M in July 2021), and DarkVision (Seed, $4M in September 2016). Trevitt emphasizes investing “as early as possible” in AI hubs like Vancouver, Toronto, San Francisco, and Seattle, targeting the full AI stack from hardware to end-user applications. His distinctive point of view centers on the convergence of data, humans, and AI to solve problems in radically new ways, as articulated in Defined’s founding announcement.
