About us
At Weights & Biases our mission is to build the best tools for AI developers. Our co-founders built Figure Eight, and our tools are being used by cutting-edge machine learning teams including OpenAI, NVIDIA, and Cohere. We’re looking for passionate, driven people who love to learn and collaborate in an inclusive work environment.
In May 2025, Weights & Biases was acquired by CoreWeave but we’re still focused on building the best tools for the era of generative AI. You can see our current open roles here.
Our start
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. As a proud part of CoreWeave, our mission remains the same.
Our values
Be curious at your core
We foster a mindset of continuous learning, understanding that curiosity drives innovation. We seek out information, question assumptions, and value different perspectives. Curiosity is a driving force that allows us to explore ideas and innovations that push boundaries, challenge the status quo, and better serve our customers.
Empower employees
We trust each other to make decisions, communicate transparently, and are clear on our goals. We support each other with the tools, resources, and feedback necessary to succeed. We know that employees can do their best work when they feel valued, supported, and heard.
Act like an owner
We take full responsibility for our work and our decisions to find the best solution to any challenge. Wait for others to solve problems? Not us – we step up, innovate, and drive progress. We take initiative, hold ourselves accountable, and foster a culture where everyone feels empowered to contribute to our success.
Deliver best-in-class experiences
Some might say we’re customer-obsessed. We go above and beyond to understand our customer’s needs and aim to exceed expectations at every step. Our commitment to excellence ensures we build lasting partnerships and set the standard for exceptional service.
Achieve more together
Collaboration is at the heart of our success. Together, we unlock greater potential and solve challenges more effectively. We believe that by leveraging diverse perspectives, supporting each other, and working as one team, we can accomplish more than we could ever do alone.
