Moat metrics

The moat, measured. Not a deck — a timestamp.

Fonteum instruments its own growth. These five metrics are collected automatically, stored append-only, and published here rolled-up and anonymized. Every number is a query against a production table, not a screenshot.

Methodology

How each number is measured.

M-1 · AI citations
A locked weekly set of real user questions is sent to ChatGPT, Perplexity, Claude, and Gemini. Each response is scanned for Fonteum URLs. The headline is the number of citations across all queries that week.
M-3 · Snapshot history depth
For each federal source family we hold, we count distinct dated snapshots. The headline sums those across families — a proxy for how much history exists that a fresh competitor cannot backfill.
M-4 · FHIR API requests
Requests to the live FHIR R4 endpoints are tallied weekly and classified by consumer (AI agents, developers, browsers). The headline is total weekly requests.
M-6 · Press mentions
Distinct news/media URLs mentioning Fonteum, discovered weekly. The headline is the count of unique mentions that week.
M-19 · Build velocity
Pull requests merged to the main branch in the trailing 7 days, read directly from version control — a founder-execution signal.

Metrics are append-only and timestamped at collection. Each tile carries its 12-month target and an honest state: live once a reading exists, pending — first run when a self-contained metric is awaiting its next scheduled collection, or pending — key when a metric is gated on an external credential or upstream feed still to be provisioned. No placeholder zeros are ever shown. Full collection details, alert thresholds, and the underlying schema are documented in the methodology index.

Instrumented, not asserted

A live FHIR R4 API, stored snapshot-attestation metadata, and an open methodology expose the evidence available for these metrics. Attestation coverage varies and does not sign each number; re-query the named source before relying on it.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
