Hey Product Hunt! 👋
I’m Eduardo, founder and builder of Stampa.

TL;DR: Digital punch cards for local businesses — with an optional collaboration layer that lets partner shops promote each other’s rewards.

Why I built this

I’m from Guatemala, and I’ve seen firsthand how many small businesses still don’t have access to simple tools to help them keep customers coming back. They rely heavily on repeat visits, but rarely have a way to track loyalty or encourage it—and most marketing platforms are too expensive or too complicated for everyday use.

I wanted to create something local businesses could actually adopt:
quick to set up, easy for any team member to run, and frictionless for customers.

That’s how Stampa started.

What Stampa does today

Right now, any café, boutique, or wellness studio can:

Create digital punch cards in minutes
Let customers collect stamps with a QR scan (no app required)
Unlock rewards instantly
See clear, actionable loyalty insights that help owners understand how customers return and redeem rewards.
Offer a process customers genuinely enjoy using

It solves the essential part of loyalty: making return visits simple and rewarding.

Collaborative rewards (already built 🚀)

A big part of the long-term vision is helping small businesses grow together, not alone.
So I built a collaboration system that mirrors how real partnerships work — based on trust and full control.

Here’s the simple version:

When Store A creates a reward, it belongs to Store A
Store A can choose to mark the reward as collaborative
Only collaborative rewards are visible to partner shops
Partner shops (like Store B) can request access to promote that reward in their own loyalty card
Store A can approve or reject the request — nothing happens without their consent
Once approved, Store B can promote that reward to its customers
Redemptions follow whatever Store A decides:
- Default: Redeem only at Store A (drives traffic back to the creator)
- Optional: Store A can allow redemption at Store B if both sides agree

This creates a safe, transparent way for local shops to support each other and share visibility without giving up ownership of their rewards.

The collaboration system is fully built. I’m opening access region by region, so each area has enough partners to make collaboration meaningful.

👉 Product Hunt users get priority access as these collaboration groups launch.
