Join the mission

Trust cannot remain implicit. Neither should your work.

Compliance evidence, audit trails and supplier attestations still run on PDFs, screenshots and emails. We're building the infrastructure that makes trust verifiable - and we're looking for people who want that to be true.

The problem we exist to solve

Modern organizations operate on unverifiable trust.

Compliance evidence, supplier attestations, operational records and audit artifacts are still largely dependent on PDFs, screenshots, emails and manually collected evidence. These systems don't provide cryptographic integrity, continuous verification or defensible provenance. Everyone who joins ROOTKey helps close that gap.

“A small but focused team united by the conviction that trust must be machine-verifiable, not implicit.”
