I built KirkList after repeatedly seeing viral products on TikTok/Instagram, rushing to Costco, and leaving empty-handed. Costco's inventory varies wildly by location but their app only shows online stock.

KirkList lets shoppers crowdsource what's actually on shelves. Spot something? Post it with location and price. Looking for that viral Biscoff Cheesecake or Stanley cup? Check what others have found nearby.

Key design decision was optimizing for quick posting - users need to snap and share while actually shopping, not fill out forms later.

Would appreciate feedback on UX and thoughts on scaling crowdsourced inventory tracking.
