CrabTap is a digital loyalty platform built for small local businesses like cafés, barbershops, and ice cream shops. Instead of building a native app or paying for infrastructure designed for bigger chains, venues get a simple, affordable way to run stamps and points programs. Customers use one account and one QR code across every participating business, earning stamps or points they can redeem for real rewards the venue sets. Owners get an easy scan-and-reward flow at checkout, along with tools to send promotions and bring back customers who haven't visited in a while. No app store, no complicated integrations, just a fast way for small businesses to reward loyal customers.
