Simulate any product experiment with AI agents grounded in your real user behavior and see predicted lift before shipping.
Simulithic builds a population of AI agents grounded in a company's last 90 days of session data to simulate how real users would interact with any proposed product change. Companies connect their session analytics tool (Clarity, PostHog, or others), define a variant, and receive lift estimates and confidence intervals in minutes. The platform supports simulating onboarding flows, copy changes, checkout funnels, redesigns, and pricing changes. Session data never leaves the customer's account. Simulithic is a product of Simulithic.
