The consortium of S3E – Southern European Entrepreneurship Engine has officially launched the S3E Reverse for Solvers Open Call #1 targeting scaling start-ups and SMEs with deep tech solutions. Through S3E REVERSE, the project creates an Innovation and Technology Brokerage Program aiming at connecting corporates and public organisations (Challenge Organisations) with scale-ups, start-ups and SMEs (Solvers) that can address the identified challenges through their products, services, and solutions, based on deep tech and aligned to the Sustainable Development Goals (SDGs). The Solvers - SMEs and more mature start-ups - are invited to join the program, submitting their solutions, ideas and products that solve one or more of the 15 identified challenges. The Open Call for Solvers is available from 14 March (12.00 pm CET) until 15 May (17.00 pm CET).
