World's first self-serve simulation platform

Rehearsals predicts conversion, retention, revenue, and customer demand by simulating how real people act and react with 92% accuracy.

  • "Why are people dropping off?"

  • "Are we leaving money on the table with our current pricing?"

  • "Are competitors launching a new product? What should we do?"

  • "Are there cohorts of customers that we're missing?"

  • "I want to add a subscription tier. Why would people want it? Why not?"

  • "Which customers are ready to upgrade?"

  • "What would make churned customers come back?"

  • "Which feature should we cut, keep, or double down on?"

  • "What objections are stopping people from buying?"

  • "Will this launch create confusion or urgency?"

  • "Which message will move fence-sitters?"

  • "Where is demand hiding by region or cohort?"

  • "How should we respond to a competitor price drop?"

  • "Why are trial users not converting?"

  • "Which audience should we test first?"

  • "Will customers forgive this tradeoff?"
