Fellows Fund

Fellows Fund is an AI-native venture firm designed to partner with founders building the next generation of foundational and applied AI companies. We operate as a brain trust of 38+ leading AI researchers, operators, and executives with experience across model development, infrastructure, and large-scale deployment. Our core belief is simple: enduring AI companies are built faster and more defensibly when founders are supported by people who have already solved the hardest technical and operational problems. Fellows Fund backs teams with early conviction, hands-on technical guidance, and access to a tightly connected network of senior practitioners who engage deeply from the earliest stages. Since 2021, we have helped cultivate one of the most concentrated AI ecosystems in the market—connecting researchers, engineers, and founders working at the frontier. Our involvement spans product strategy, system architecture, go-to-market execution, fundraising, and talent, tailored to each company’s technical depth and stage of growth. Our portfolio includes 7 AI-native unicorns—Abridge, Replit, Physical Intelligence, Periodic Labs, Harmonic, Higgsfield, and Gamma—category-defining companies reshaping healthcare, software creation, autonomy, and knowledge work. In addition, we have backed 50+ breakout AI startups since 2021, including OpusClip, GC AI, Corgi Insurance, Motion, Artisan, Evidently, Truewind, Yoneda Labs, and many others shaping the next wave of AI-driven businesses. Fellows Fund is built for founders who want deeply informed partners, long-term conviction, and a community aligned around durable technological impact. Learn more at
