PANews reported on December 3rd that Antithesis, a startup focused on distributed system stress testing, has completed a $105 million Series A funding round. The round was led by Jane Street, with participation from Amplify Venture Partners, Spark Capital, Tamarak Global, First In Ventures, Teamworthy Ventures, and Hyperion Capital, as well as individual investors such as Patrick Collison, Dwarkesh Patel, and Sholto Douglas. The new funds will be used to expand the engineering team, increase automation, and expand global market reach.

According to reports, the company employs deterministic simulation testing technology to provide production-level fault simulation services for blockchain and financial systems. The Antithesis platform can simulate real-world network environments on a large scale, accurately reproducing edge case failures and helping engineers locate system vulnerabilities that are difficult to reproduce through traditional debugging methods. The company revealed that the Ethereum network used its services to simulate extreme scenarios before its "merge" upgrade, and its clients currently cover the financial, AI, and blockchain sectors, with revenue growing more than 12 times in the past two years.
