Thesmios

Developers and partners

The trust layer should have an API.

Thesmios is designed to become infrastructure that other systems can call, embed, and build on.

Integrations

The first integrations follow the workflows where trust is repeatedly rebuilt.

ATS

Greenhouse, Lever, Workable

Identity and verification

Right to work, DBS, HEDD, professional registers

SSO

Data

Companies House, sanctions lists, regulatory registers, media, courts

API direction

The API will expose evidence, not black-box conclusions.

Consumers of the API should see source, status, verification level, refresh date, reviewer action, and subject contribution. The system should be inspectable because compliance needs evidence.

  • Profile read API for consented evidence packs.
  • Check request API for regulated workflows.
  • Webhook events for profile update, credential expiry, match review, and remediation status.
  • Partner sandbox for HR, ATS, travel, and regtech integrations.

Partner programme

We are looking for HR, ATS, travel, background screening, and regtech partners who want portable evidence instead of repeated checks.
