Challenge
The problem we walked into.
Helio’s clinicians were spending 4+ hours a day on documentation, killing throughput and morale. Off-the-shelf LLMs failed compliance and hallucinated confidently on medical data.
Solution
What we built.
We built a bespoke RAG + eval pipeline with a fine-tuned model over 1.2M de-identified notes, wrapped in a linter for medical citations and an audit trail meeting HIPAA and SOC-2.
