Gregory St clair

I’m the founder of Authentica, an AI-powered authentication app for sneakers, designer bags, and luxury goods. It delivers a verdict from phone-camera photos alone — no shipping items off, no waiting days — in under a minute. We launched on the App Store in July 2026. Under the hood I architected a multi-pass AI verdict system with an identification-consensus layer and evidence-completeness scoring to eliminate false verdicts, and built the full brand, content engine, and creator-led go-to-market. We’re positioned against incumbents like Entrupy and CheckCheck on speed, cultural fluency, and a creator-first distribution model
