100% Focused on Product

Build Sec Foundry is here to challenge founders and accelerate new products to market while building a security ecosystem in downtown San Antonio.


Our entire program, network and resources were created to help founders accelerate development, launch their product and build a successful go to market strategy.


Built within the nation’s second largest ecosystem for security companies, defense missions and talent, we have built a network ready to test, validate and deploy new disruptive security technology.


We office out of Geekdom, an expansive, shared workspace in downtown San Antonio, that fosters an entrepreneurial community of connecting, sharing, and improving ideas.

Accelerate Through Focus

Incubation periods for early-stage startups vary but deciding where to focus energy is critical. Build Sec will help you eliminate the outside noise and zero in on what is most important.
