"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 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..."
