BuyerIQ

Gary Tan posted on Twitter on a Friday about how LLMs can simulate purchase intent. That night I built BuyerIQ. By Sunday I had seven paying customers.

You paste your website link or describe your product. BuyerIQ runs synthetic buyer simulations across 100+ demographic segments, predicting who will buy and why. The whole process takes under 30 seconds.

The methodology is grounded in a peer-reviewed paper: LLMs Reproduce Human Purchase Intent via Semantic Similarity Elicitation. The system matches real consumer behavior at 90% accuracy, validated against 9,300 actual shopping decisions.

BuyerIQ has generated several thousand dollars in revenue and helped several hundred founders with early-stage market validation.
