This is a founders-only event.
BUILD617 is a cobuilding space built exclusively for venture-backed, early-stage founders. Some of Boston's best founders are already working out of the space and we're looking to fill out the remaining spots with the right startups.
Selected founders get:
Complimentary workspace at BUILD617
A built-in community of other venture-backed founders building in the same room
Direct access to the people running the space
This event is your chance to see the space firsthand, meet the founders already building there, and enjoy a great dinner on us.
Space is extremely limited. This is invite-only for Boston's top early-stage founders.
Built in Boston. For builders, by builders.
And a huge thank you to our friends at Synergy for their support of BUILD617 and for sponsoring this event, especially Dave Greaney, Kevin Marsh, and Rachel Kirby Sandeman.
Synergy has been an incredible partner in helping make this space possible. Their support is helping create something truly first of its kind for Boston founders: a dedicated cobuilding space where the city’s top early stage startups can build side by side at no cost.
Dave in particular has been an amazing resource for the tech and founder community here in Boston, and as an incredible founder himself, he deeply understands what this kind of space can mean for the next generation of companies being built here.
