About the foundation

Who we are

our story

March 2004

Founded in Barcelona by MCRIT Ltd

Ersilia is a private non-profit foundation devoted to building a collaborative, active learning culture for facing urban challenges, local and global alike.


Founded on 2 March 2004 in Barcelona by MCRIT Ltd, a consultancy specialised in urban and regional planning, the Foundation works across four interconnected areas. It communicates and disseminates research and innovation projects, translating complex findings into narratives that reach policymakers, practitioners, communities, and funders across Europe.

It designs learning and capacity-building programmes that draw on Design Thinking, Systems Thinking, and Theory of Change to help people navigate complexity and lead systemic innovation, with particular emphasis on green, digital, and resilience skills. It facilitates stakeholder engagement and strategic decision-making, running inclusive multi-actor processes and Living Labs where citizens, academia, industry, and government co-explore sustainability transitions. And it supports innovation and start-ups, mentoring entrepreneurs and changemakers as they turn systemic insight into viable, context-sensitive solutions.

Guided by humanity, communication, creativity, and sustainability, Ersilia believes that changing ourselves is the first step toward changing the world, transforming knowledge into action for the common good. The Foundation upholds a quality policy aligned with applicable legal requirements, and has adopted a gender equality plan implementing a non-discrimination policy at work.

Where the name comes from

One of Calvino’s
invisible cities

“The inhabitants stretch strings from the corners of the houses —  white, black, grey, or black-and-white —  according to whether they mark a relationship of blood, of trade, authority, agency.“

In Italo Calvino’s Invisible Cities, Ersilia is a city built not from walls but from threads. When the strings grow so dense that you can no longer pass among them, the inhabitants leave and what remains is the spiderweb of relationships seeking a form.

We took the name because it describes our work exactly. We don’t build monuments; we weave the connections that let knowledge travel between people, institutions and territories and we leave capacities behind when we go.
