FirstMark Capital

FirstMark is a New York City-based early-stage VC firm investing primarily at Seed and Series A in disruptive technology companies across enterprise software, AI/ML, consumer marketplaces, fintech, healthtech, developer tools, and cybersecurity. The firm takes a founder-first, long-term partnership approach—frequently acting as the first institutional investor—and supports portfolio companies through IPO and beyond via its extensive platform: Data Driven NYC (20,000+ members), Guilds (C-level exec communities tied to 80%+ of global unicorns), and full lifecycle recruiting and network access. Occasional pre-seed checks ($250K–$500K) are made for exceptional repeat founders. Check sizes range from ~$250K to $10M+, with the firm often leading rounds.
