Flybridge Capital Partners

Flybridge Capital Partners is an East Coast seed-stage venture capital firm with over 20 years of investing experience and more than $1 billion under management across six seed funds and seven pre-seed funds. The firm focuses exclusively on pre-seed and seed investments by choice, partnering with founders from day one and remaining deeply involved in the ups and downs of company building as trusted advisors and confidantes. In September 2025, Flybridge announced its seventh seed fund—Flybridge 2025—a $100 million vehicle dedicated to backing world-changing companies that unlock the potential of AI. Flybridge's current investment thesis is organized around three interconnected layers of AI enablement. The first is AI Infrastructure and Developer Platforms: just as the firm backed core infrastructure in the cloud era (MongoDB, Firebase), it believes the next generation of enablement software will be built for an AI-native stack, backing companies such as Arcade, Arcee, Blitzy, Fiveonefour, Mako, Portkey, and TrojAI. The second is Agentic Business Applications—the 'action layer'—where business software is shifting from 'AI-assisted' to 'AI-initiated,' backing agentic systems that act on behalf of users, transforming work from knowledge processing to decision-making and execution, with portfolio companies such as AllSpice, BrightHire, Covenant, Syrup, Topline Pro, MelodyArc, and Prime Security. The third is Native AI Applications for Human Potential—the boldest bets—backing companies creating entirely new ways to work, create, and relate that are native to AI and reimagine human behavior rather than merely augmenting it. Flybridge's thesis is rooted in the belief that the next generation of transformational companies will be built on modern AI infrastructure, with a particular emphasis on founders who demonstrate what the firm calls 'Minimum Viable Founder' qualities: singular obsession with a specific problem, high agency and belief in themselves, and unconventional achievement. The firm targets 8–10 core seed investments per year at the GP level, alongside 40+ pre-seed investments annually through its unique Next Wave ecosystem—a network of 50+ founders, entrepreneurs, and executives from top tech companies (e.g., Anthropic, NVIDIA, OpenAI, Toast) who lead investments at the edge of the thesis. Operating for decades out of offices in New York City and Boston, Flybridge views its East Coast positioning as a strategic advantage—rooted where customers and builders converge, from Harvard, MIT, NYU, Cornell, and Columbia research networks to the largest enterprise customers in every industry. The firm describes its approach as a 'pit crew' rather than a platform: built by former founders who know what early-stage builders actually need, embedding with strategic networks that open doors and doing the hard things others won't. With a seed-to-Series A graduation rate more than twice the industry standard and a track record of 8 IPOs, 11 unicorns, and $10B in exit value across 100+ backed companies, Flybridge has established itself as a premier early-stage partner for AI-native founders on the East Coast.
