Synthetic Labs is an A/B testing platform for business decisions you can't actually test in the real world, like pricing changes, plan launches, or anything irreversible. From a single plain-English sentence, it uses Gemini 3.5 Flash to generate a diverse population of agent archetypes who each have their own background and reasoning, then lets them argue, persuade each other, and decide, so you can watch how a real customer base would react before you ship. It solves the core problem that real A/B tests cost months, can't evaluate one-time decisions, and surface failure modes too late, whereas Synthetic Labs returns a defensible recommendation in minutes. In our demo it not only recommended a student plan for Anthropic but flagged a competitor-style free trial as do-not-ship, catching agents coordinating to redeem and cancel before renewal, a failure mode no spreadsheet would surface.
