— FOR MANAGERS & LEADERS

First-time managers learn the hard conversation by having it.

Tough feedback to a top performer, peer disagreement with a senior leader, expectation reset with an overcommitted teammate — your managers practice these against an AI that responds like a real human, before they have to do it for real.

— The problem

Promotion to manager doesn't come with the skill set.

Your newly-promoted senior engineer is now responsible for a tough feedback conversation by Friday. PowerPoint training won't get them ready. Coaching sessions are weekly at best. They need reps, and the only place to get them today is the live conversation.

On-demand
reps before the meeting

Run the practice conversation at 9pm the night before. Your manager walks in calm because the AI already pushed them harder than the real teammate will.

Authored
on the actual person

Describe the teammate in plain words. The AI character mirrors their tone, stakes, and pushback. Not a generic "difficult employee" template.

Per-axis
growth tracking

Empathy, clarity, holding the message under pressure — each scored separately. See your managers improve over months, not vibes.

— See it in action

Three conversations every new manager has to learn.

45-second samples — different conversation types, the same AI engine pushing back behind the scenes.

— FEEDBACK DOWN

Tough feedback to a top performer

Star engineer ships fast but burns peers. Deliver the message without losing them — or watering it down.

— DISAGREE UP

Pushing back on a senior leader

VP wants to ship a feature you think is wrong. Disagree without being dismissed. Frame it as their decision, not your veto.

— RESET SIDEWAYS

The overcommitted teammate

A peer keeps over-promising and missing dates. Have the boundary conversation without making it personal.
