Maggie McCullough

Maggie McCullough is the CEO and founder of PolicyMap, the Philadelphia-based mapping and data-visualization platform she launched in 2008. A former White House budget-office staffer turned housing researcher, she built PolicyMap after struggling to fit maps and data into her own policy work, betting that anyone should be able to make a map as easily as they shop online. The platform now serves universities, banks, health systems, nonprofits and governments, layering thousands of public and proprietary datasets into one searchable map. In December 2023 the company closed a $3 million Series A led by its former parent, the Reinvestment Fund.
