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 Co:here. We’re looking for passionate, driven people who love to learn and collaborate in an inclusive work environment.

Our start

Before Weights & Biases, founders Lukas Biewald and Chris Van Pelt had already ridden the start-up train together building Figure Eight. When pondering about their next project, Weights & Biases came to fruition during Lukas’ internship at OpenAI.

While working with some of the world’s most renowned machine learning researchers, Lukas realized the tools they were using were outdated and inefficient. To build better models, they needed better tools.

Launching a new company is hard, so to round out the team, Lukas and Chris pulled in Shawn Lewis — a long-time friend who also had a founder’s experience. Together, they used their combined knowledge, skills, and experiences to create tools that could support machine learning practitioners and move forward the state of the art of machine learning.

Our values

Honesty

To make smart decisions, we need to be honest with each other and with ourselves. Honesty allows us to surface problems so we can tackle them together as a team, instead of avoiding them.

Curiosity

Machine learning is advancing fast. Best practices can easily become obsolete overnight. The key to thriving (not just surviving) in this industry is to never stop learning.

Gumption

In a world of intense competition, having the confidence to move forward despite uncertainty is essential. Taking risks can be uncomfortable but staying complacent is rarely the better option.

Grit

As much as talent counts, effort counts twice. Having that ability to roll up your sleeves converts setbacks into stepping stones. In the long run, having grit is a core part of success.
