CipherAI raises $75M to commercialize a private LLM with verifiable outputs for healthcare

AI · 5 min read

CipherAI introduced a private LLM product designed for healthcare customers that combines on-prem deployment, encrypted weights, and a novel attestation layer that signs model outputs to prove they originate from a certified model run. The company highlights compliance and auditability as core differentiators.

The $75 million Series C was led by Aurora Capital with participation from institutional healthtech investors. Funds will go toward SOC2/ISO7K readiness, clinical partnerships for evaluation, and accelerating inference optimizations so hospitals can run the model on modest GPU clusters.

CipherAI is positioning the product for clinical decision support, prior authorization workflows, and patient communication automation. Beta partners include regional health systems that will contribute to validation datasets while keeping PHI strictly on-premise.
