Alterra Labs is the safety and alignment company for AI in healthcare and the life sciences.

Our team of over 60 clinicians, scientists, ML researchers, and engineers, builds technology to understand and improve AI model behavior. Clinical judgment, real-world practice, and dedication to patient care and treatment are the foundation of our work.

Our name translates to “another earth.” We conduct rigorous evaluations by building realistic simulation environments to reflect the decisions and consequences that AI will face in the worlds of healthcare and life sciences.

Alterra partners with frontier AI labs, applied AI companies, health systems, life sciences organizations, national medical societies, non-profits, and governments to ensure that AI model behavior is being evaluated, analyzed, and aligned before, during, and after deployment. Our partners use our research to make their models valuable, trustworthy, efficacious, and safe for patients.

As models continue to develop increasingly sophisticated capabilities, aligning model behavior to be safe and reliable is both a critical requirement and a progressively more challenging problem. This is a non-static goal. As the world changes around us and as frontier model capabilities continue to expand, we will need to continuously re-evaluate and re-align behavior.

There is often no ‘right answer’ when taking care of a patient or conducting an experiment. The reasoning behind an action matters just as much as the action itself. By our measure, a model that solves a task for the wrong reasons has failed it. Setting the bar for trustworthy clinical judgment is a difficult technical problem, with high stakes for getting it wrong.

This is what we’re building at Alterra: the ability for models to advance medical and scientific knowledge faster than ever before, and unlock our capacity to deliver abundant, affordable, and highest quality care to anyone, anywhere in the world.
