Runs usability tests on Figma prototypes, live sites, or screenshots using AI personas instead of recruited participants, returning results in minutes.
Why it matters for PMsLets you pressure-test a flow before you spend a recruiting cycle on it, killing weak concepts at the spec stage rather than after build.
An agent inside Hex notebooks that writes SQL and Python, builds charts, and iterates on analyses against your warehouse data.
Why it matters for PMsCuts the wait on the 'can you pull this cohort?' ticket, so you can check a launch metric yourself instead of queuing behind the data team.
Launched today alongside AOP Copilot and Simulations, it runs phone support agents and tests changes against simulated customer conversations before release.
Why it matters for PMsSimulations give you a way to regression-test support automation the way you test features, before a bad policy change reaches real customers.
