Built by people who have lived the verification problem.
The team behind Marker has worked across AI simulation and evals, safety validation, recommender systems, production infrastructure, and data tooling used by real operators.
We are building Marker because high-stakes AI agents need the same discipline that safety-critical systems already depend on: repeatable tests, clear failure evidence, and audit trails that stay inside the customer environment.
