Simulithic runs AI agent simulations that model real user cohorts—built from a product's last 90 days of session data—to predict how experiments and product variants will perform before shipping to real users. It integrates with session tools like Clarity and PostHog and returns predicted metrics such as lift, confidence intervals, churn, and activation for product and growth teams.
