Innovative Technology: TerraNeon Chooses Nantes
Co-founded by Jean-Daniel Kant, a professor and researcher in artificial intelligence (AI) and cognitive science at Sorbonne University, and Maël Franceschetti, who holds a Ph.D. in AI, TerraNeon draws on 20 years of research. “We create an artificial world that resembles the real world, and then we test different solutions in it,” explains Jean-Daniel Kant.
Shedding Light on Complex Decisions
In practical terms, TerraNeon virtually replicates a complex system using computational agents that represent individuals, businesses, infrastructure, market mechanisms, and more—this is known as “multi-agent simulation.” This solution makes it possible to compare multiple scenarios based on their feasibility, cost, social acceptability, resilience, and impact on the climate or biodiversity—and to make the best decisions regarding investment, planning, or transformation! Designed for both businesses and local governments, TerraNeon can provide valuable insights for projects related to energy, transportation, industry, and decarbonization.
Nantes, a place to call home
After also considering Rennes, the two Parisian co-founders ultimately chose Nantes as their base and arrived in the region last June. “We found just about everything we needed here: local governments that are very dynamic and committed to the ecological transition, a strong industrial base, and a region open to digital technology,” explains Jean-Daniel Kant. The presence of recognized incubators such as Atlanpole and IMT Atlantique—which the startup joined in July 2026—also played a key role in the decision.
Supported First Steps in the Community
To help it establish a foothold in the region, TerraNeon has been supported by Nantes Saint-Nazaire Développement since December 2025. This includes an immersion day in the heart of Nantes’ industrial sector, identifying events to attend—such as Energies Day—and connecting the company with local stakeholders and networks… : “Nantes Saint-Nazaire Développement serves as our link to the region and helps us identify the right contacts,” emphasizes Jean-Daniel Kant. Next step: finding clients willing to test TerraNeon’s technology on real-world projects, in Nantes or elsewhere, to demonstrate its effectiveness in the field.
