At Weights & Biases, our mission is to build the best tools for AI developers. We founded our company on the insight that while there were excellent tools for developers to build better code, there were no similarly great tools to help ML practitioners build better models. Starting with our first experiment tracking product, we have since expanded our solution into a comprehensive AI developer platform for organizations focused on building their own deep learning models and generative AI applications.
Weights & Biases is a Series C company with $250M in funding and over 200 employees. We proudly serve over 1,000 customers and more than 30 foundation model builders including customers such as OpenAI, NVIDIA, Microsoft, and Toyota.

- Mentor fellow engineers, sharing best practices and advocating for long-term architectural solutions.
- Enhance data models and systems to ensure accurate, fair, and transparent billing processes.
- Develop tools and integrations for internal teams to seamlessly use billing data for better decision-making and customer service.
