// On the floor · Anthem Armory
The first company building here.
Anthem ArmoryExterior study
These startups are housed here today — working companies on the Atlas floor, not just members, putting the shops and tools to work as they build.
An intelligent plumbing company founded in San Diego in 2024, built around preventative care rather than one-off repairs. Homewerx pairs licensed plumbers with smart water monitoring and a membership model tuned to the region’s hard water — a technology-forward take on a traditional trade.
A San Diego maker of paintball replicas of classic WWII firearms — historically detailed markers built for collectors and scenario play. Anthem Armory prototypes and builds on the floor, putting the shops’ machining and fabrication tools to work.
An early-stage venture firm backing founders building hard infrastructure — defense, AI, energy, and space. Zero Gravity looks for companies that are hard to build, hard to replicate, and strategically indispensable: the kind of deep-hardware work that starts on a floor like this. They’re the capital in the room when a prototype is ready to become a company.
We work with companies that make physical products in San Diego — sharing shop space, tooling, and the occasional late night. If you’re building hardware and want a home for it, come talk to us.
