Alex Lines is a co-founder and Partner at Notation Capital, a Brooklyn-based venture firm he established in 2015 after serving as Chief Architect at Betaworks for four years. He focuses his investment thesis on hard tech, infrastructure, and technical product teams, primarily at the Pre-Seed and Seed stages across the United States with a concentration in New York. Notation Capital’s typical check size ranges from $250,000 to $2 million, positioning the firm to make first checks for idea-stage founders. His notable portfolio companies include Spruce, Livepeer, Bison Trails, and Parsec, which reflect the firm’s emphasis on infrastructure and product-centric startups. Lines distinguishes himself by working closely with technical teams on strategy, team building, and product development rather than仅提供 capital. The firm explicitly targets “product-obsessed founders on day zero” to support fundamentally new experiences in fringe markets that may become mainstream.
