Boston has the talent. Boston has the capital. What's missing is the connective tissue.
B4 is the community that makes Boston's startup scene feel connected, visible, and alive. Less talking, more building.
Boston's startup scene is fragmented.
World-class universities, deep capital, incredible talent. But no connective tissue. Communities stay siloed. Founders stay invisible.
B4 is the fix. We create the collision moments, visibility, and real relationships that make an ecosystem work.
Where builders meet builders
Two lanes of events, one goal: genuine connection.
Every event is designed for one thing: genuine connection.
Built by a founder, for founders
George Le, Founder of B4 / Angel Investor
“I started my career in Boston. I stayed because I believe this city can be the best place to start a company. It just needs people willing to make that happen.”
George is a Boston-based angel investor who saw firsthand how fragmented the city's startup ecosystem had become. Great founders were building in isolation. Investors and operators existed in separate orbits. B4 started as a simple idea: bring builders together in the same room, consistently, and let the connections do the work.
