Frontier AI models are advancing faster than the ability of health systems, payers, life sciences companies, and AI builders to verify what those models can safely do. Healthcare work is long-horizon, tool-heavy, and consequential, and existing benchmarks do not measure it. While the largest AI labs have reportedly considered spending more than $1.0 billion on reinforcement learning environments, healthcare remains the domain where this infrastructure is least developed.
Alterra Labs builds the full stack required to measure and improve AI behavior in healthcare: simulation environments that faithfully reproduce real healthcare software, graded evaluations, expert clinical judgment, and post-training data. An in-house team of more than 40 practicing clinicians works alongside machine learning researchers to author each task, rubric, and failure analysis, which enables frontier labs, applied AI companies, and health systems to see how models fail before they reach a patient.
Safety and alignment company for AI in healthcare and the life sciences that builds realistic simulation environments to evaluate how AI models reason and act in clinical and scientific settings. Alterra Labs partners with frontier AI labs, health systems, life sciences organizations, and governments to evaluate and align model behavior before, during, and after deployment. The company’s team of more than 60 clinicians, scientists, machine learning researchers, and engineers helps its partners build AI that is trustworthy and safe for patients.
