Boston Founder CommunityBuild Your Network is the always-on community for startup founders in Boston. Connect with founders building in biotech, medtech, robotics, edtech, and deep tech, find mentors who've done it before, and get in front of investors actively looking at Boston deals.
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.
