Startup Antithesis turns years of real-world chaos into hours of simulated mayhem—and key trading firms and crypto networks are paying close attention

Will Wilson wants to make sure the software running everything from your bank account to your favorite crypto exchange actually works—and his company Antithesis is rethinking how software has been tested for the last 80 years.​​

Wilson, the co‑founder and CEO of Antithesis, first made his name at FoundationDB, a company that created special testing systems that let teams safely rehearse years of real‑world problems in a fake environment, to catch bugs before customers ever saw them (FoundationDB was acquired by Apple in 2015). That idea—stress‑testing code inside a simulated universe where everything that can go wrong does—is now the core of Antithesis, a deterministic simulation testing platform that runs fully automated, parallel tests that can compress years of production behavior into hours.​​

“Software increasingly controls literally everything,” Wilson told Fortune, pointing to financial markets, banking websites, smartphones, and even nuclear power plants. The traditional model of writing code and then trying to think of every possible edge case “is totally broken,” he argued, because failures come from situations engineers did not anticipate. Antithesis runs customer systems in a controlled simulation where hardware failures, network glitches, and bizarre timing issues are........
