Collaborative Fund
About Collaborative Fund
Craig Shapiro founded Collaborative Fund in 2010. The firm is based in New York City and has roughly $1 billion in assets under management, according to Wikipedia. Wikipedia lists Andrew Montgomery, Guy Vidra, Morgan Housel and Sophie Bakalar as partners alongside Shapiro. A Form D for Collab PL - A, L.P., filed through Collaborative Fund Management LLC, was reported in June 2026. The filing summary found does not state an amount, and no partner-level AI lead is named in the sources reviewed.
The firm's portfolio page keeps AI as its own category, with companies including Phaidra, Osmo, Haiqu, Speak and Reflex. Phaidra, which builds AI agents for AI factories, raised a Series B of more than $50 million in 2025, and Collaborative Fund led that round. In August 2026 the firm took part in a $5 million seed for Osmo Studio, an AI video tool maker, that Bain Capital Ventures led. The Lounge deals desk also logs a $50 million AI seed for Sabi in October 2026. No other public detail on Sabi was found.
Crunchbase's portfolio hub lists Pre-Seed, Seed and Series A among the stages associated with the firm's companies. The firm also led a Series B for Phaidra in 2025. No check size range is published in the sources found, so none is given here.
