The S3E Open Call #2 has officially launched!

The S3E – Southern European Entrepreneurship Engine consortium is excited to announce the official launch of the second Open Call for the three tracks of the S3E Program: Start, Charge & Reverse.

S3E is the ultimate program of support for entrepreneurs in Southern Europe developing Deep Tech solutions with social and sustainable impact at their core. Each track is dedicated to three main groups operating within the innovation ecosystem: researchers and TTOs working on a project as a team, startups at their growth stage, and corporates interested in joining forces with scaleups/SMEs.

What’s the difference between the 3 tracks?

  • S3E Starthelps research teams and tech transfer officers to explore the commercial viability of their deep tech projects. Through an 18-week online training & mentorship program, the selected research teams will learn first-hand about the processes required to develop a business case for science-based products or services.
  • S3E Charge: supports deep tech startups in their growing phase that want to improve their business model and learn how to access dilutive and non-dilutive funding. Over 14 weeks, the selected startups will receive tailored mentorship to guide them through the validation process of their product or service, and the creation of an investment-ready business plan. 
  • S3E Reverse: connects corporate challenges with solutions developed by scaleups and SMEs thanks to the Brokerage Program, based on a successful open innovation methodology. To access the first phase of this track, large companies and public organisations have to submit a deep tech challenge.

You can find all the relevant information about each track on the Apply Now section on this website.
