Million Software, Inc.

We are on a mission to fix the web.

1. We open-source tools like React Doctor and React Scan, which developers have run × to find and fix issues in web apps.
2. We build ReactBench alongside custom datasets, reinforcement learning environments, and traces. These resources train and evaluate frontier coding agents on realistic web development work.

If we pull this off, anyone will be able to ship software that rivals what the best-funded teams build.

Backed by Scott Wu, Amjad Masad, Evan You, David Cramer, Matt Biilmann, Sam Lambert, Nikita Shamgunov, Sahil Lavingia, Theo Browne, Koen Bok, John Pham, Ben Vinegar, Dane Knecht, Paul Klein IV, and Y Combinator (W24).
