    What Does Antithesis Do?

    Name: Antithesis

    Headquarters: Vienna, VA, United States

    Employees: 51-200

    Antithesis is a software platform specializing in autonomous testing designed to help engineering teams build and verify complex systems. Antithesis provides a solution for automated, deterministic testing, enabling organizations to uncover elusive bugs and performance issues that traditional testing methods often miss.

    The platform leverages advanced simulation and continuous, autonomous exploration to test software at scale. By simulating real-world scenarios and systematically searching for edge cases, Antithesis aims to ensure that systems behave reliably under any conditions. This approach is trusted by leading technology companies including Palantir, MongoDB, Ethereum, Snowflake, Apple, Mysten Labs, and WarpStream by Confluent.

    How was Antithesis started?

    Antithesis was founded by a team with extensive experience in deterministic simulation and large-scale systems engineering. The founding team includes:

    • Will Wilson (CEO): Previously worked on deterministic simulation testing at FoundationDB, Apple, and Google.
    • Dave Scherer (CTO): Creator of vPython, co-founder of Visual Sciences and FoundationDB, programming since age five.
    • Nick Lavezzo (COO): Has collaborated with the leadership team since 2003 and co-founded FoundationDB.
    • Ben Collins (VP of Engineering): Led the FoundationDB team at Apple.
    • Hao Guan (VP of Sales): Worked with Dave and Nick at Visual Sciences and Adobe.
    • Jeremy King (VP of Services): Led implementations at Visual Sciences; former Senior Product Manager at Adobe.
    • Michael Fortunato (Controller & VP of Finance): CPA with experience at KPMG and as a Controller at several companies.
