Baselayer is a Know Your Business (KYB) platform that verifies US entities against authoritative registration and risk data. It resolves a business by name and address and returns the full profile: officers, state registrations, entity structure, and verification status.

​
Use it for

  • KYB onboarding and vendor/customer verification.
  • Due diligence on officers, registrations, and entity structure.
  • Screening businesses for risk and watchlist hits.
