Your expertise is your moat

A foundation model is a starting point. Your internal knowledge, ways of working, and standards of quality give your agents something distinctive to learn.

Your sessions

The decisions, tool calls, and corrections that show how your team works.

Your tasks

Real problems from your business give agents something meaningful to learn from.

Your standards

Processes, policies, and accepted examples define what good looks like. Verifiers make it testable.

Your expert feedback

Approvals and corrections capture the judgment behind great work for your team to review.

One proxy in front of your agents.

Connect supported tools through Gateway and use captured trajectories to inspect and compare agent behavior.
