Discover Our Story.

Humming’Card was founded in October 2025 as part of the Rotterdam School of Management’s SDG Ambassadors Program. While working on SDG 12 – Responsible Consumption & Production, we came up with a simple yet powerful idea: a sustainable student discount card that makes responsible choices easier, and more rewarding.

Our mission is to bridge the gap between responsible production and conscious consumption, creating a true win-win-win. Students enjoy exclusive discounts, our partners engage in a meaningful sustainability initiative, and above all, the planet benefits from better consumption habits.

In December 2025, we took the next step by launching the Humming’Card App, expanding our impact and further promoting awareness of the Sustainable Development Goals within student communities.
We are grateful for the support of Erasmus University Rotterdam and proud to collaborate with a growing network of committed, sustainable partners.

The journey has only just begun… 💚
