Most reliability engineering happens after something breaks. Will Wilson thinks that's the wrong place to be. As co-founder and CEO of Antithesis, the autonomous testing platform that just raised $105M in a Series A led by Jane Street, Will has spent years building the infrastructure to catch failure modes before they ever reach production. His starting point is uncomfortable: the testing practices most teams rely on are structurally incapable of finding the bugs that cause real incidents.

In this episode, Will traces that argument from its origins at FoundationDB, where a small team used deterministic simulation to ship a near-zero-bug distributed database at speed, to Antithesis's bet that any software system can be made fully testable without rewriting it. The conversation covers fault injection without production risk, the limits of chaos engineering as it's practiced today, and why the explosion of AI-generated code makes a reliable testing foundation more urgent than ever.
