Builder Bay is where defense tech gets built.
A homebase for founders, engineers, and operators shaping the future of national security—and the hard tech that powers it. From autonomy and aerospace to energy and maritime, this is your community.
What We Believe
We're not in the desk business. We're in the 1+1=3 business.
Builder Bay was founded on the belief that the right people in the right room accelerate each other's missions.
Our members aren't just sharing space. They're exchanging hard-earned insights, forming strategic partnerships, and building trust that compounds over time. That's the multiplier effect of a real community. And that's why we exist.
This is a place where the next great defense tech company might be sparked over a whiteboard session, a cold brew, or a DoD roundtable.
Builder Bay is built differently.
We're not for everyone. We're for:
Early-stage defense tech and dual-use founders who are serious about execution.
Engineers, scientists, and end-users working on problems that matter.
Investors, operators, and partners who want proximity to frontier innovation.
This isn't coworking. It's community-powered innovation.
Join Builder Bay to:
Build alongside serious founders solving national security challenges
Meet DoD stakeholders, VCs, and industry leaders in curated settings
Accelerate with trusted feedback, honest intros, and real collaboration
Be part of a broader movement to rebuild American hard tech
What We Offer
Builder Bay is structured around a few core components:
Curated Community
We vet every member. Our goal is to keep the signal high and the energy focused. You'll find autonomy startups, AI/ML defense founders, blue tech pioneers, and dual-use VCs here.
Physical Workspace
Need a place to land and work? Great. We offer flexible space options. But remember: space is the feature. Community is the product.
Events + Programming
We host regular roundtables, strategy sessions, guest speakers, and demo days. You'll walk away with more than ideas—you'll walk away with relationships and ideally customers.
Strategic Connections
We actively make connections between founders, funders, DoD contacts, and technical experts. We help you find the people who will move your mission forward.
