Judgment's scorers work really well out of the box - saved us a lot of dev time.

Judgment's environment data gave us research-quality datasets from our real agent environment interactions we couldn't get anywhere else.

We exported our thousands of agent evals from Judgment and used them for agent RL training - our task completion rate jumped 20%.

Honestly didn't think we needed evals until we tried it. Catches stuff we never would have seen.
