Hey Product Hunt I'm Shyamkiran Kotnana, Co-founder & CMO of Synthetic People. Here's the problem we kept running into: teams want to move fast, but customer research is still stuck in a world of weeks-long surveys and panels that cost tens of thousands of dollars, especially for hard-to-reach or niche audiences. By the time the results come back, the market has already moved. So we built Synthetic People: a simulation layer where you can test concepts, messaging, pricing, product trade-offs, and "what-if" scenarios using behavior-grounded synthetic personas, built on real consumer actions, neuroscience signals, and multi-source calibration. Think of it less as "AI replacing customers" and more as a wind tunnel; you still fly the real plane, but you don't want the first test to be the real flight. We're also obsessive about not overselling this. That's why we built a public Test Lab, where we rerun real human surveys through Synthetic People and publish exactly how close (or how different) the results are: similarity scores, directional alignment, and where the two diverge. Would love your feedback, questions, and even your skepticism. Ask us anything below
