## Description

Antithesis provides an autonomous software testing platform for engineering teams building mission-critical systems. Its deterministic simulation technology runs a complete software system under stress, injects realistic clock, scheduling, network, and storage faults, and explores scenarios that conventional testing may miss. The platform aims to uncover severe bugs, reproduce them reliably, and provide automated root cause analysis, helping developers fix issues without lengthy investigations.

Teams can use Antithesis in continuous integration, in local development workflows, or through agent skills. The company also offers skills, command-line tools, and APIs to help AI agents onboard projects, develop behavioral specifications, and run verification. Its custom hypervisor supports time travel and alternate execution paths, while intelligent exploration tests thousands of distinct scenarios in minutes.

Antithesis serves organizations working on capital markets, databases, event streaming, blockchains, ledgers, and distributed systems. Customer examples include Jane Street, Formance, Tigris Data, and PingThings. By helping teams find unexpected failures earlier and verify changes faster, Antithesis supports more confident releases, fewer critical failures, and faster software development.
