Viewpoints AI

Viewpoints.ai is a synthetic persona-based market research platform built by Stanford media psychologists, enabling brands, legal teams, and researchers to generate research-grade consumer feedback on ads, products, concepts, and messages — with same-day results. The platform was founded by Leo Yeykelis, who holds a Stanford Ph.D. in Human-Computer Interaction and spent 12+ years leading research at Google, Waymo, VMware, Toyota, and Vine. Co-founder Jim Cummings holds a Ph.D. in Communication from Stanford and has authored 50+ publications with over 4,000 citations. The company's synthetic audiences are grounded in media psychology and marketing science developed over decades of peer-reviewed research — more than 250 publications and 36,000+ Google Scholar citations across the team. In a published validation study, Viewpoints.ai synthetic persona responses matched human study results 88% of the time on medium and large effects. Use cases include pre-testing advertising creative, product concepts, messaging strategies, and legal mock trials. The platform is headquartered in Mountain View, California, and targets marketing teams, consumer insights professionals, and trial attorneys who need fast, rigorous audience feedback without the time and cost of traditional panel recruiting.
