About Workers IO
YC company profile
Simulation environments for verifying mission-critical software
Workers IO is building simulation environments to catch failures in mission-critical software before they reach production. We run your entire system through millions of simulated production scenarios to verify its correctness and performance properties.
Coding agents can now generate code faster than teams can review it. Meanwhile, software and the infrastructure it runs on keep getting more complex. Tests check a small set of cases in isolation, in environments that are different from production. Some of the most expensive failures only surface when customers encounter them.
We run your entire system unmodified and simulate network faults, disk failures, crashes, and clock drift. We build the fault models for you and check your system’s requirements across millions of scenarios. Every failure we find can be perfectly reproduced.
