Ealyx

About us

Ealyx is the first platform and payment method that turns trade-ins into instant discounts at checkout — with zero risk to the merchant. By unlocking the value of what people already own, we boost both circularity and sales.

We launched this year with strong traction: shoppers love it, and merchants see +52% higher Average Order Values. Backed by over €2M in pre-seed funding, we’re building an AI-native product and creating a new category world-wide.

We move fast, challenge each other to grow, and care about building great things sustainably.
