Clean Cities Spain ClimAccelerator - Demo Day 2025

The Demo Day of Clean Cities Spain ClimAccelerator is the meeting point where innovation, entrepreneurship, and sustainability come together to drive the transformation of our cities. After an intensive 9‑month program, developed in collaboration with the Polytechnic University of Madrid and EIT Climate‑KIC, the fifth cohort of international startups will present their most disruptive projects in key areas such as renewable energy, smart mobility, and sustainable materials.

The event is a unique showcase to discover pioneering technologies and connect with a diverse community within the ecosystem: top‑tier investors, leading corporations, public sector representatives, and experts in climate innovation.

The day not only offers the opportunity to meet the next generation of climate tech leaders, but also to generate strategic synergies that accelerate the transition towards cleaner, more livable, and fairer cities.
