About us

Weights & Biases was born behind a karate studio in San Francisco with a simple but ambitious goal: to build the best tools for machine learning. And though the field has evolved dramatically since the company shipped its first product, that single animating focus has never changed.

When Weights & Biases was founded by Lukas Biewald, Chris Van Pelt, and Shawn Lewis in 2017, tools for machine learning practitioners were fundamentally inadequate. Tracking models was mostly a manual exercise; reproducing them was practically impossible. But deep learning was still advancing rapidly. Image recognition was reliable. Voice recognition was on every phone. Lukas, Chris, and Shawn shared the conviction that better tools could help their peers solve bigger problems.

What began with an experiment tracking solution developed to help build models at OpenAI grew into an end-to-end MLOps platform used by thousands of businesses and millions of practitioners. But nearly a decade later, the mission remains the same.
