Looking back at Demo Day 2025: Concrete projects and signed contracts
On June 17, the seven startups from the SEED 2025 cohort showcased their projects during Leonard’s annual Demo Day. After six months of support, these young companies pitched their ideas to dozens of investors, experts, and VINCI Group collaborators.
This day marked the end of one chapter and the beginning of a new one for these startups. Several have already signed contracts with operational entities within VINCI.
