Simulation Environments for Verifying Software
We built Workers IO to make it possible for engineering teams facing high-availability pressure to verify their end-to-end systems at a scale and depth that real-world deployment demands. Our platform simulates millions of interleavings, fault cases, and timing scenarios to pinpoint the exact conditions that can break critical software invariants. Existing tools don't catch the edge cases that take systems down in production - we help teams find and fix them before they ship.
San Francisco, CA, USA. We'll stay based here after YC.
We're in San Francisco because it's where most infrastructure buyers, developer talent, and partners are. It also gives us the best access to early adopters and other high-bar engineering teams.
