comethru - Post-event retargeting through branded wallet passes

by
comethru replaces event check-ins with branded Apple and Google Wallet passes, no app download required. When attendees save a pass, brands unlock the ability to retarget them via SMS, email, and social after the event ends. Most brands spend big on activations and walk away with zero data. comethru gives you a digital touchpoint you actually own, so your event ROI doesn't disappear when the booth comes down.

Hey Product Hunt 👋 We built comethru because event marketing has a dirty secret: brands spend $50K+ on activations and leave with zero follow-up ability. Here's how it works: Your brand distributes a digital pass (Apple/Google Wallet) at any live event Attendees save it in one tap, no app download required You retarget those exact people via SMS, email, or social after the event We're live with D2C brands and experiential agencies. Would love your feedback, especially from anyone who's run event activations and felt the pain of "so... now what?"
