Autonomous Software Testing Company Antithesis raises $30M

Antithesis, the autonomous software testing company, today marks its first year anniversary since launching out of stealth with the announcement of new funding and the expansion of its customer base, employee count, and board.

Antithesis has significantly increased its customer base in the last year, expanding its penetration into the crypto and database industries while entering new industries, including fintech, utilities, financial trading, travel/logistics, and data streaming. In response to growing demand for its pioneering software testing and debugging technology, the company, headquartered just outside Washington, D.C., has grown its headcount by over 50% and is set to double that in 2025. It has also expanded its footprint to the West Coast, with senior go-to-market and product hires in San Francisco, and plans to further build its presence there this year.

Antithesis has also raised an additional $30 million in funding led by Amplify Partners, with participation from Spark Capital, and has added Lenny Pruss, General Partner at Amplify Partners, to its board of directors. Clay Fisher, General Partner – Growth at Spark Capital, has also joined as a board observer.

Antithesis’s autonomous testing platform aims to drastically increase the reliability of software. It allows organizations to innovate faster, deliver a higher-quality product to customers, and avoid potentially disastrous bug-related outages and disasters. Once integrated into a software development workflow, Antithesis scans code for bugs inside of a separate simulated environment and can perfectly reproduce every bug it finds while providing powerful debugging information. This eliminates the need to manually write and maintain tests and test cases, allowing engineers to focus their time on feature development.
