How do you build a startup that could change the way millions shop online — all before your 20th birthday?

In this episode, Startuprad.io dives into the game-changing IDAN system with Julian Pfeiffer, founder of KeyOne, who started his company at just 15. From the football field at Eintracht Frankfurt to leading one of the most exciting fintech e-commerce innovations in the DACH region — Julian’s journey is one for the books.

We explore how the IDAN (International Delivery Address Number) streamlines online checkout, enhances data privacy, and reduces delivery errors — all while helping merchants boost conversion and cut costs. If you care about startup innovation, e-commerce, or digital payments, this episode is for you.
