Join Free in Boston How it works

What is the startup founder community in Boston?

Boston's startup ecosystem spans biotech, medtech, robotics, edtech, and deep tech, supported by MIT, Harvard, Mass General Brigham Innovation Hub, and Flagship Pioneering. Boston is America's deepest science and technology ecosystem — anchored by MIT and Harvard, which produce more startup founders per capita than any other universities in the world. The city's biotech cluster in Kendall Square is the most concentrated biotech ecosystem globally, and its robotics, medtech, and climate-tech sectors are world-leading.

Build Your Network brings this community online — founders, mentors, and investors all on one platform, each declaring their intent so every connection is purposeful.
