Libu develops biomimetic lighting systems that reproduce natural sunlight to align indoor lighting with human circadian rhythms. Its core product modulates intensity, spectrum, and color temperature over a 24-hour cycle to improve health and performance. The technology follows three years of research by optical engineers Manon Loustau and Tinou Seguin and is associated with studies reporting about a 25% reduction in perceived stress. Libu has commercial traction across offices, open-plan areas, factories and 24/7 sites and lists partnerships with Suez, Capgemini, Colas, and Enedis. The company announced a €1M fundraise supported by ADI Nouvelle-Aquitaine and a syndicate of business angel funds to intensify commercialization, increase production capacity, expand its product range for industrial needs, and strengthen the team. Its stated focus is scaling deployment and extending the product line to address diverse professional environments.
