About Enact
Summary
Enact builds the post-training layer for physical AI, generating targeted data that makes robotics models reliable in real-world deployment. The company runs a closed improvement loop: deploying policies on tasks, identifying failure states, and producing demonstration and recovery datasets to fix those failures. It replaces the manual, ad hoc process robotics teams use to find model gaps and collect the data needed to close them.
Go-to-market
Robotics teams seeking real-world training data engage Enact directly by submitting a data request, pointing to a sales-led or request-based intake model.
