TestCart AI

Theodoros Sofianos is the founder of TestCart AI, the platform that turns a photo of any retail shelf into a walkable 3D store where real and AI shoppers reveal what gets noticed, considered and chosen before launch. He previously co-founded Digital Bites, where he pioneered reconstructed-environment testing: rebuilding real stores in VR and combining them with neuromarketing research protocols to measure shopper behaviour instead of shopper opinion. Across 800+ consumer tests, those protocols were validated with Nestlé, Unilever, pladis, Pescanova, Wageningen University and AB Vassilopoulos, and now underpin TestCart's correlation between virtual-shelf and real-world behaviour. A Forbes 30 Under 30 honoree and keynote speaker on ecological validity in consumer research, Theodoros is building TestCart with a US focus, to give brands and agencies shelf-level behavioural evidence in days rather than months.
