4YFN26:
Powering startups

4YFN is a four-day event that takes the boring stuff seriously. Success isn’t all inspiration, innovation and networking. Although…… you will experience plenty of that too.

2-5 March, 2026 | Fira Gran Via Barcelona
4YFN Entrance, Hall 8.0 & 8.1

Be boring enough to power your startup.

Startups are about ideas, inspiration and innovation, but the reality is also about perspiration, tenacity and the little details. The boring stuff. This is where startups succeed and fail. At 4YFN we will guide you through the whole journey, from inspiration and perspiration, to the little details that drive success.

2026 theme - Infinite AI

Nobody knows the boundless potential of AI, but we come close.

AI is making headlines everywhere.

Behind the hype, it’s actually the unglamorous but persistent, behind-the-scenes thinkers —prompting, refining, reworking — who drive real change. It’s time to swap hype for substance. To transform bold ideas into insightful human sessions that reveal AI’s true potential.

Last year with AI XL, we went big. With Infinite AI, there’s no ceiling on where we’ll go next.

Who is behind it?

4YFN knows who.
