Scale Your Expert Community

Hire flexible, credentialed, verified clinicians to cover demand spikes. Let Folio manage sourcing, matching, training, coverage, time tracking, contracts, and compensation.

Reinforcement Learning from Human Feedback (RLHF)

Generate preference pairs that reflect real clinical reasoning. Our experts evaluate response quality based on clinical accuracy, safety, and adherence to standard of care in real care settings—not just fluency.

Rubrics & Verifiers

Transform complex clinical protocols into structured evaluation criteria your models can learn from. We convert unstructured clinical knowledge into measurable verification tasks.

Safety & Red‑Teaming

Models fail in surprisingly human ways: a triage suggestion that downplays red‑flag symptoms, or a draft note that quietly invents an allergy. We work with med students, nurses, residents, and other clinicians‑in‑training to probe for these failure modes, map them into patterns, and give your teams concrete targets for hardening guardrails before they touch patients or staff.
