Flybridge is an AI-only early-stage venture firm that primarily backs founders at pre-seed and seed, with a strong concentration in NYC and Boston. The firm is explicitly founder-driven, prefers to be first to believe, and combines high-conviction early bets with selective follow-on capital for breakout companies after Series A.
Flybridge is explicitly founder‑driven at the earliest stages: “At the earliest stages of investing, the founder is everything.” They formalize this in a “Minimum Viable Founder” framework that emphasizes a singular obsession with a problem, high agency, and unconventional thinking. Beyond the founder, they evaluate founder‑problem fit, a very large multi‑act TAM, a technical product edge that does not over‑rely on PhDs, a human‑AI interface that earns trust, a go‑to‑market edge that pushes teams beyond pilots, and proprietary data moats or “earned secrets.” Decisions are high‑conviction but not unanimous, allowing decisive bets when confidence is strong. They prefer to build relationships early via Next Wave pre‑seed investments and then lead or co‑lead seed rounds. Their thesis has narrowed to AI‑only, building on a history in developer and data infrastructure that informs how they assess modern AI stacks and application‑layer opportunities.
