The S3E Project is back!

S3E Open Call #2 is now live and officially open for submissions.

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.

So here's a recap of what each of these tracks is about:

S3E Start: helps 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 our 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.

The easiest way to understand how to apply for each of the tracks is to follow the official S3E project website.

Key dates

It's important to remember the most important dates of the project.

Join our upcoming S3E Info Webinars!

To help this year’s applicants prepare for their submissions, the teams behind S3E Start & S3E Charge will be hosting a series of Q&A Webinars. These sessions provide an open space to everyone interested in applying to ask any questions they may have about the S3E Program — we highly encourage future participants to come along!

Check the available dates for S3E Start (here for portuguese sessions and here for international sessions) and S3E Charge (here) and book your preferred session via Eventbrite. The earlier you join one of our Info Webinars, the more time you and your team will have to prepare before submitting your application.
