4YFN26 in Numbers — Innovation, Startups, and Infinite AI

Barcelona, March 2026 – This year’s 4YFN26 edition, held alongside MWC 2026, brought together the global innovation ecosystem like never before. With a focus on the theme Infinite AI, the event highlighted how artificial intelligence is not just a tool, but a transformative layer shaping startups, corporates, investors, and the way we interact with technology. 

Here’s a look at 4YFN26 by the numbers, revealing the scale, energy, and impact of the event.

Infinite AI — the thread connecting every conversation

From keynote sessions to private meetings, AI emerged as the central narrative. This year’s theme emphasized AI as an invisible layer of transformation, integrated into infrastructure, business processes, and everyday life.

• Investors focused on startups building AI infrastructure rather than just AI products.
• Founders discussed the importance of trust, transparency, and ethical deployment.
• Corporates explored partnerships with startups to embed AI into enterprise workflows.

The message was clear: AI is no longer optional — it is foundational, and those who master its application will shape the next era of innovation.
