SUPPORT

Email-first. Self-service docs cover most pre-sale questions.

Response times are governed by your tier's SLA. We don't currently run a phone-tree or live chat — we run email, Slack (Standard+), and public documentation. The constraint here is a feature: a small founder-led team that responds personally beats a phone tree.

SELF-SERVICE

Most procurement questions are already answered

Before emailing, the following pages cover what most procurement and engineering teams ask first:

  • /methodology — how every published figure was computed
  • /data-provenance — the per-record provenance contract
  • /sources — every registered source family with refresh cadence + ToS notes
  • /refresh-cadence — how stale a record can be at any tier
  • /research — every shipped study with downloadable CSV/JSON
  • /security — data scope, infrastructure, vulnerability reporting
  • /sla — uptime + response-time targets per tier
  • /terms — standard B2B terms; pilot agreements supersede

Built on the authoritative federal record

The primary sources, named on every page.

These are the federal agencies whose public datasets Fonteum ingests and attributes — the issuing authorities, not customers or partners. Every figure on the site links back to one of them.

  • CMS
  • HHS-OIG
  • HRSA
  • FDA
  • NLM
  • NUCC
  • Census
  • BLS
  • BEA

Reproducible by design

Every figure traces to its federal source.

14-tuple provenance

Every rendered fact ties to a source URL, dataset ID, snapshot date, row key, and SHA-256 — the full chain-of-custody record.

Reproducible SQL

Each study ships the exact query behind its figures, run against the cited federal snapshot. Re-run it yourself.

Daily reconciliation

Published counts are reconciled against the upstream federal datasets on a daily cadence, with drift logged.
