"For us the most valuable thing we took advantage from is the network of contacts. Thanks to the Demo Day, we are in a quite advanced conversations with a potential client which came up from this session. The chance to share lessons learnt with the startups was very inspiring as, at the end, we share some common challenges."

"Thanks to the programme we were able to connect with key public actors from the ecosystem. Our services will be used for projects within a city council in Spain. We had the chance to get to know more about the potential collaboration for international projects as startup. I would like to highlight the opportunity to connect with more startups working on the same field as well."

"The university plays a fundamental role in building a public-private collaboration framework and promoting innovation initiatives from a systemic perspective and in an environment of co-creation in aspects as important as urban transformation towards climate neutrality. "

"The technology and the business model have grown significantly. We have been able to develop and test new digital functionality for our patented water saving technology, capable of saving up to 25 litres with each shower or hot water use. We tested it in a real environment thanks to one of the program partners, who are now clients and potential investors of the startup."

"Entrepreneurship plays a key role in the transformation of cities towards climate neutrality. City councils have a roadmap and actions to take, but they cannot do it alone. "The participation of all public and private agents is necessary to face environmental challenges."

At the same time, corporations are in contact with disruptive ideas, new business models..."

"All the collaborating institutions of the program are from the beginning in the very ideation of the accelerator, which means that the profound and far-reaching changes for the transformation of cities can be materialized more easily through the innovative solutions that arise."

"Participating in the Clean Cities Climaccelerator has been an extraordinary experience. Beyond developing solutions for more sustainable cities, I had the opportunity to explore the innovation ecosystem in Spain. This experience made me realize how crucial collaboration between countries is to tackle climate challenges and drive innovation. A program that combines global vision with local impact!"

"The Clean Cities Spain programme was an incredible experience! The training was priceless, inspiring us to refine our approach and explore new urban applications for our solar-powered water technology. We made such great connections with other startups and gained confidence. We're excited for what the future holds!"
