About

Loyalty cards should be simple for every small shop.

Treuly is a digital stamp card a café, bakery or salon can set up itself — from a phone, in minutes, with no technical know-how at all. The app is on the App Store — and you can be part of it from the start.

Why Treuly exists

Until now, good loyalty tools weren’t built for small shops.

Small shops live on their regulars. But the paper stamp card gets lost, and "proper" loyalty programs are built for chains — with hardware, setup fees and contracts a single café doesn’t want to pay for. Treuly closes that gap: a loyalty card you set up yourself, that your customers don’t have to download, priced honestly — free to start, one flat monthly price with no per-customer charge when you want more. No IT budget needed, no sales call.

The people behind Treuly

Built by hand, in Germany.

Treuly is built by Bonyad Nouri and Dennis Achtziger — two AI engineers who studied mathematics and used to work in hospitality and service businesses themselves. They know customer loyalty from behind the counter, not from slide decks. Today they build — fully self-funded, operated by Printproof UG (haftungsbeschränkt) — the tool they wish they’d had back then: customer loyalty that’s simple and affordable for a small café, bakery or salon too.
