I've spent years helping DTC brands grow, from early-stage startups to brands doing hundreds of millions in revenue. The one thing that consistently slows teams down is the gap between having an idea and knowing if it's the right idea.
Traditional consumer research is broken for DTC. It's too slow, too expensive, and too disconnected from how fast you actually need to move. I built Thesis to close that gap, to give brand and growth teams the same consumer signal that enterprise brands get from $50k research studies, in the time it takes to write a brief.
The AI agents aren't a gimmick. They're trained on real demographic and psychographic data, and they respond the way real consumers respond, with nuance, with context, and with the kind of honest feedback you'd get from a well-run focus group.
