The Walk Score Team

Jesse Kocher, Walk Score co-founder
Jesse Kocher

Jesse was formerly the Director of Web Strategy at the New Progressive Coalition (NPC), a company that advised political investors on managing their investments in progressive organizations. Jesse led the tech team through NPC's first two launch cycles, creating online tools for investors to build and manage their portfolio of political investments.

Jesse and Matt have been working together since they met at Brown University. In 1999 they founded the software startup EQuill, a Web development software company they sold to Microsoft in 2001. In 2004, they founded Driving Votes together, and Jesse created and ran the organization's website which helped thousands of volunteers meet and share rides on their trips to register Democratic voters in swing states. Jesse graduated from Brown in 1999 with degrees in Computer Science and the Visual Arts.
