Barcinno x 4YFN: Full List of Side Events During 4YFN25 and MWC 2025

Barcelona will once again become the beating digital heart of the tech and startup ecosystem as 4YFN and the Mobile World Congress (MWC) return to the city on March 3–6, 2025. 

Co-located on the same site, 4YFN is the official event partner of MWC Barcelona – the world’s largest and most influential connectivity event. So together, you can expect another 10,000+ innovators, founders, and investors from around the world to gather for this unrivaled meeting of talent, ideas, and opportunities.

Barcinno has been Barcelona's go-to English-speaking resource for all things startup and tech for over a decade. Their annual 4YFN and MWC event guide has helped attendees navigate this epic week's exciting calendar of both official and unofficial events. And 2025’s edition is no different. 

Events list: What to expect

While the official agenda provides plenty of connection opportunities and inspiration, Barcinno’s annual guide is perfect for visitors looking for more – as well as those hoping for specific industry niches. Want to meet other young founders over casual drinks, strategize with fellow investors, or network with sales peers, developers, or women in tech? You’ll find it on the list. Here’s a quick look into some of the events, both long-standing and brand-new this year:
