Hi everyone — Mark here, founder of Brewstamp. I built this after watching every independent cafe I visit fumble with paper punch cards — customers losing them, owners reordering boxes of them every few months, no way to know if any of it is actually bringing people back. Brewstamp replaces all that with one QR code. You print a single A4 sheet, tape it to the counter, and you're done. Customers scan with their phone camera — no app to download, no account to create. They collect stamps in the browser and redeem free drinks when they hit your threshold. Real numbers from one of our customers (Bennett St Dairy in Bondi, Sydney) after 7 months on the platform: • 863 customers enrolled • 4,940 stamps awarded • 121 customers actively scanning weekly • Daily regulars hit their reward inside 2 weeks • One A4 QR poster replaced an entire box of punch cards The customer-facing card translates into 13 languages so cafes anywhere can use it without re-printing. Free up to 100 stamps (enough to validate it actually works for your shop). $5/mo after that. No customer app, no contracts, no card-printing. What I'd love feedback on: • The free-to-paid threshold — is 100 stamps the right tier line? • The customer-side UX — try scanning a QR if you're at a cafe that uses us • Anything obvious I'm missing for a shop owner's first 5 minutes Happy to answer anything in the comments. Thanks for taking a look 🙏
