Interpretability and reasoning infra for foundation models
We are building an SDK that lets foundation model builders analyze, steer, and control their models' behaviors. Unlike general-purpose ML tools, our product surfaces interpretable insights and reasoning paths inside large models, so teams can debug, improve, and regulate them reliably at scale.
We live in San Francisco, CA, and plan to stay based here after YC.
San Francisco is the center of AI and ML innovation with easy access to early adopters and talent. It makes sense to remain here to stay close to the ecosystem.
