Innovation live on stage: Frankfurt School Demo Day inspires

The Frankfurt School Entrepreneurship Centre hosted its Demo Day Summer ’25 on 1 September, drawing a record turnout. The centre’s flagship event brought together founders, investors and ecosystem partners on campus showcasing promising pre-seed startups. The competition concluded with TwinWatt winning first place and NovaVoca securing second place. Together, the two teams were awarded a total of 50,000 euro in prize money.

The Entrepreneurship Centre  fosters early-stage innovation by providing resources, mentorship, and investor connections, helping founders transform pioneering ideas into scalable businesses.
