About Rehearsals

GPAgent's own fund-neutral profile, written from public information. Updated Sep 25, 2026.

Summary

Rehearsals builds a self-serve simulation platform that lets marketing and product teams test decisions against AI digital twins of real customers. Teams upload ad creatives, pricing concepts, or product flows and get predicted outcomes across thousands of parallel simulations in minutes. The platform replaces traditional research cycles: focus groups, surveys, and waiting weeks for customer feedback on pricing, messaging, churn, and launch strategy.

Business model

Self-serve access to a library of 50,000 existing consumer replicas, with the option to bring proprietary customer data.

Go-to-market

Marketing and product teams at companies sign up and run simulations directly through a self-serve onboarding flow, starting by speaking to a voice agent to configure their first Rehearsal.
