ABOUT
A federal-data research bureau for the AI era
Fonteum is a public-benefit research bureau building the citation layer between agentic AI and US healthcare data. We believe that if a model is going to reason about hospitals, doctors, and patients, it should cite the federal record. Not approximate it.
When a model reasons about a hospital, a physician, or a patient population, it usually does so over an opaque data lake it cannot cite. The result is healthcare answers that sound authoritative and are quietly wrong: a closed facility marked open, an exclusion that was lifted years ago, a specialty inferred from a stale aggregator. The cost of that error is not a bad search result. It is a clinical or financial decision made on a number nobody can trace. Agents do not need another aggregator. They need a citation.
Fonteum resolves every claim over 22 federal source families, each value snapshot-pinned to the exact dataset release it came from, assigned a DOI so it can be cited the way a paper is cited, and signed so the snapshot cannot be silently altered. The same federal record is public to everyone; the moat is not access. The moat is reproducibility — the ability to hand any reader, regulator, or downstream agent the exact path from a published claim back to the byte it was drawn from.
We do not sell the data. The federal record belongs to the public. What we sell is the proof: a fourteen-field provenance contract on every value, a methodology published in full and version-pinned, and a signed snapshot chain so any claim can be reproduced by someone who has never spoken to us. That is the wedge. Anyone can scrape a federal file. Almost no one can show their work.
Every claim is reproducible
We publish the methodology, version every snapshot, and assign DOIs so any figure can be cited and re-derived from its source.
Every source is federal
We do not aggregate proprietary or scraped data. We resolve over public federal records: NPPES, OIG LEIE, CMS PECOS, CMS Care Compare, and CMS Open Payments, plus HRSA, BLS, and BEA.
Every response is signed
Cryptographic attestation via SLSA L3 and SHA-256 snapshots, so an agent's citation can be audited downstream.
