Start4big was created as a collaborative initiative between Aigües de Barcelona, CaixaBank, Naturgy, SEAT and Telefónica, with an aim to partner with the world’s most disruptive start-ups and develop impactful solutions for the customers. Our objective is to identify disruptive technologies and leverage on them to solve business challenges. Start4big will launch challenges to the global community of entrepreneurs and select the best start-ups to collaborate on development of their solutions. These participants will get an opportunity to test and scale up their projects, having access to key resources, experts and know-how of the Start4big partnering companies. The initiative seeks to strengthen the Spanish entrepreneurial ecosystem - one of the most important ones in Europe - and pursues the creation of a global community that encourages synergies between strategic sectors and key players.
