Reynard is market simulation software that tests product ideas, pricing strategies, and marketing campaigns using a census-weighted panel of simulated personas. Users can describe their scenario and receive detailed reports within minutes, including acceptance rates, verbatim feedback from eight population groups, and market-readiness scores. Simulations are based on public census data and iterative proportional fitting, with databases for the Netherlands and the U.S., each containing over one million profiles weighted to census data. Responses are segmented into eight mindset groups using the Motivaction Mentality framework. Reynard offers one free daily simulation without requiring an account, while paid simulations include expanded features like additional voices and scenario testing. Reports are available in English and Dutch, with options to follow up with simulated respondents. The platform operates on a one-time payment model instead of a subscription.
