Antithesis

Antithesis is an autonomous software testing company founded in 2018 by the team that built FoundationDB. It develops a deterministic testing platform that uses fully deterministic, massively parallel simulation to explore software behaviour exhaustively, drawing on intelligent guidance, property-based testing and fault injection. The platform explores thousands of alternate execution paths, and every bug it surfaces is perfectly reproducible, with root cause analysis and complete reproduction steps supplied alongside it.

The company's technical work spans deterministic simulation testing, massively parallel simulation, property-based testing, fault injection, root cause analysis and distributed systems testing. Its stated aim is to eliminate flaky tests and help engineering teams ship with confidence. Since 2018 the firm has operated largely quietly while refining the approach.

Antithesis's platform is applied across databases, distributed systems, fintech applications and blockchain protocols. Further information is available at https://antithesis.com/.
