5. Claimed vs. verified metrics tracker

5.1 Metric categories

  • "Users," "customers," "members," "accounts" (registered vs. funded vs. monthly active vs. primary-account)
  • TPV/GMV vs. net revenue; take rate
  • "Profitable" (adjusted EBITDA, contribution profit, GAAP net income, one-quarter vs. full-year)
  • APY/"up to" rates vs. base rates and conditions
  • "No fees" vs. fee schedule reality (instant transfers, out-of-network ATMs, FX, tips)
  • Fraud-reduction and AI-performance claims
  • Valuations (priced round vs. tender vs. secondary marks vs. market cap)
  • "Available in X countries" vs. licensed product availability
  • Financial inclusion and "financial health" outcome claims

5.2 Verification protocol

  1. Capture the claim (source, date, exact wording, archived link).
  2. Locate the best primary counterpart (filing, fee schedule, terms, regulator data).
  3. Record the verified value with definition and period.
  4. Classify: Matches / Consistent but narrower definition / Materially different / Unverifiable.
  5. Assign confidence; publish neutral explanations (not accusations).
  6. Offer the company a right to reply where publishing a material discrepancy (editorial policy).
