A wave of young leaders is shaking up the Rennes scene. Three profiles stand out: Clément Quéguiner, Claire Bretton, and Benjamin Verlingue, each bringing a new momentum that blends technology, ecological transition, and support for local entrepreneurs. They do not just create their own businesses: their strength lies in their desire to build ecosystems where cooperation prevails. Their strategy? To root themselves locally while maintaining a broad vision, activating university networks, tailored support systems, and competitiveness clusters.
Their impact is manifested in multiple ways, as illustrated by these initiatives:
- Clément Quéguiner, a driver of digital innovation, connects research and SMEs, developing technological synergies.
- Claire Bretton, a figure in high social utility projects, designs solutions focused on impact and resilience.
- Benjamin Verlingue, at the interface between traditional sectors and new markets, stimulates territorial transformation through innovation.
By betting on collectivity and openness, they are building a more adaptive, inventive, and united entrepreneurial Brittany, while ensuring that its roots are preserved.
