Signal 1, led by CEO Tomi Poutanen, focuses on assessing LLM performance for healthcare AI platform applications. In a discussion with The Derby Mill team (IntrepidGP's healthcare AI podcast series), Poutanen outlined Signal 1's methodology for evaluating which LLMs are appropriate for specific healthcare platform contexts — a capability that is increasingly critical as health systems must choose between multiple competing foundation models.

Signal 1's work addresses a practical governance challenge: health system CIOs and clinical informatics teams need structured frameworks for evaluating LLM performance that go beyond general benchmarks to assess clinical-context-specific accuracy, safety, and reliability. Signal 1's assessment approach is designed to provide this clinical-context specificity.

The company's positioning reflects the maturation of the healthcare AI market from "which AI should we use?" to "how do we rigorously evaluate and manage the AI we deploy?" — a shift that requires ongoing performance monitoring rather than one-time procurement evaluation (see managing-ai-platforms-healthcare).
