FLASHGuard Project

After an incredibly competitive selection process, the Youth Start-Up Competition jury praised the outstanding quality, creativity, and impact of this year’s submissions. The finalists stood out with their innovative solutions addressing some of today’s most pressing challenges — from renewable energy and disaster response to cutting-edge cancer treatment.

Among the three finalists is Gonçalo Ribeiro, a PhD Fast Track student at Instituto Superior Técnico in Lisbon, leading the FLASHGuard project — a pioneering medical technology enabling the safe clinical use of FLASH Radiotherapy. This innovation aims to transform cancer treatment by protecting healthy tissue while maintaining tumour control, positioning Europe at the forefront of advanced healthcare innovation.

In November 2025, Gonçalo Ribeiro will pitch FLASHGuard live at the SME Assembly 2025 in Copenhagen, Europe’s flagship event for entrepreneurs and policymakers. The winner will be crowned Youth Start-Up Champion 2025 and will go on to attend the EIC Summit 2026.
