In 2011, Overdeck and his wife Laura established the Overdeck Family Foundation, an organization that funds educational research and [STEM education](/source/STEM_education).[3][22] The foundation's overall goal is to enable all American children to unlock their potential by strengthening learning in and out of school.[23]

The Overdecks' education philanthropy focuses on four key issue areas: "early impact", "exceptional educators", "innovative schools", and "inspired minds".[24] They have made gifts to [Robin Hood Foundation](/source/Robin_Hood_Foundation) for work by [MDRC](/source/MDRC) to study the long-term effects of various early childhood programs. The Overdecks have also supported the [Harlem Children's Zone](/source/Harlem_Children's_Zone) within its early impact strategy and the [Khan Academy](/source/Khan_Academy).[24] Other grantees have included the NJ STEM Teaching Fellowship, and Governor's School for the Sciences at [Drew University](/source/Drew_University) in [New Jersey](/source/New_Jersey).[25] Laura Overdeck is an alumna of Governor's School and was instrumental in saving the program through private donations in 2006.[26][27]

This is the second gift from the Overdeck Family Foundation, the first of which was $1 million donated in 2016.[23] That same month, the Overdeck Family Foundation pledged $3 million to [Opportunity Insights](/source/Opportunity_Insights), a policy and research institute based at [Harvard University](/source/Harvard_University) that will publish data on the probability that children will escape poverty based on where they were raised.[28][29][30]
