The mission of the S3E – Southern European Entrepreneurship Engine is to develop an engine of growth that will contribute to improving the connectedness and efficiency of the entrepreneurship ecosystems in Southern European countries. Within this framework, we are seeking experts (evaluators, mentors and brokers) to support our mission. Evaluators will be responsible for assessing proposals submitted by research teams, and growth start-ups in response to the S3E Start Open Call (for research teams and TTOs) and S3E Charge Open Call (for startups). Mentors for deep tech projects will guide research teams in developing a business case for a product, service, or process grounded on a technology proposed to the S3E Start Program. Mentors for deep tech growth startups will assist in developing an investment-ready business plan within the framework of the S3E Charge Program. Deep tech brokers will match corporate challenges with the solutions offered by scaling startups in the S3E Reverse Program.
