About Antithesis

Antithesis helps engineering teams find and fix bugs that traditional testing misses.

Our platform runs entire systems in a deterministic simulation, breaks them in every imaginable way, and provides engineers with root cause analysis and perfect reproduction. The result is faster debugging, more reliable software, and more confidence in what ships.

As AI accelerates software development, the need for reliable verification is only increasing. Antithesis exists to solve that problem.

We are well-funded, deeply technical, and building a category-defining platform for modern software reliability.
