Overdeck Family Foundation

John and Laura Overdeck created the foundation in 2011 after building Two Sigma. The couple transferred a portion of their hedge-fund wealth into the vehicle to focus exclusively on education. Laura Overdeck also runs the separate Bedtime Math Foundation, which operates math clubs and an app for elementary students. The foundation deploys capital through grants rather than direct investments or fund commitments. It targets early childhood development, STEM enrichment, and K-9 student-centered environments. Confirmed distributions include support for Khan Academy, Robin Hood Foundation, and Opportunity Insights. Geographic reach centers on the United States with emphasis on measurable improvements in learning outcomes. Ticket sizes range from $125,000 to $6 million. The organization employs 23 professionals at its New York headquarters. John Overdeck holds board roles at the Institute for Advanced Study and the National Museum of Mathematics.

The foundation also maintains holdings in Recursion Pharmaceuticals and index vehicles alongside its primary allocation through Two Sigma. A structural feature is the separation between the foundation and the Overdeck family’s operating businesses. Governance keeps philanthropic decisions distinct from Two Sigma investment activity while still drawing on the same quantitative discipline for grant evaluation.
