What Libu does

Libu is a French B2B startup founded in 2019 by engineers Tinou Seguin (Directeur général) and Manon Loustau (Présidente), headquartered at the Institut d'Optique d'Aquitaine in Talence near Bordeaux. The company designs and manufactures circadian LED lighting systems that automatically adjust color temperature (1800K-6500K) and intensity throughout the workday to replicate natural sunlight cycles and regulate users' biological rhythms. The product portfolio comprises ceiling LED panels (Pavé 60x60 and Pavé 120x30, both sold with proprietary control drivers), a portable standing luminaire (Nomade, 3600 lumens), and a desktop supplementary task lamp (Cayola, 1800K-6500K range, eco-designed in oak and bio-sourced plastic). The technology reproduces 95% of natural sunlight properties at 95% circadian-cycle precision and meets UGR<19 glare and IRC>95 color-rendering thresholds.

The company targets a workplace-wellness problem in office openspaces, meeting rooms, rest areas, control rooms, and warehouse/logistics environments where artificial lighting disrupts employee circadian rhythms, contributing to sleep disorders, elevated stress, and productivity losses. Differentiation rests on a patented LED architecture, clinical validation through a 3-month epidemiological study (+4% sleep quality, -25% stress, -7% drowsiness, +7% mood) co-designed with Inserm chronobiology researchers, NF EN 12464-1 compliance, an average 60% energy savings claim, and 100% French manufacturing through partnerships with Synergy SCOP (electronics, an adapted enterprise) and Holight (mechanical assembly). Commercial operations run on a direct enterprise sales motion with bespoke quote-based pricing, multi-year contracts, and bundled lighting audit and illumination-plan services; named enterprise customers include Enedis, Capgemini, Suez, Cultura, Colas, and Institut d'Optique.

Libu operates as a private SAS under legal entity LIBU SAS with registered capital of €61,473 and a small team of 1-10 employees. The company is currently active in the Nouvelle-Aquitaine region of France only, with no international footprint disclosed. In March 2024, Libu closed a €1 million seed round from a syndicate of 3A Venture, Adour Business Angels, Arts et Métiers Business Angels, INSEAD Business Angels Alumni France, and Synergence to accelerate commercialization of its circadian lighting solutions.

Core offering

Libu designs, manufactures, and sells circadian LED lighting products for professional office environments in France. Its portfolio includes ceiling-mounted LED panels (Pavé LED 60x60 and 120x30), a portable standing luminaire (Nomade), and a desktop task lamp (Cayola), all integrating patented technology that automatically adjusts light intensity and color temperature throughout the day to mimic natural sunlight cycles and support employee circadian rhythm regulation, sleep quality, and workplace well-being.

Product overview

Libu offers a suite of circadian lighting products designed for professional environments. The core portfolio consists of four LED lighting solutions: Pavé LED 60×60 and Pavé LED 120×30 (ceiling-mounted LED panels for modular ceilings), Nomade (portable standing luminaire), and Cayola (desktop task lamp). All products integrate Libu's proprietary patented circadian LED technology that automatically adjusts light intensity and color temperature throughout the day to mimic natural sunlight cycles, supporting human biological rhythm regulation. The products target professional workspaces including open spaces, meeting rooms, rest areas, and warehouses.

Broad incumbents

• Signify (Philips Lighting): Signify, the Philips lighting parent, offers tunable-white and connected office lighting systems including circadian-oriented solutions across a global footprint. It is a broad incumbent with overlapping capabilities but competes at much larger scale and across many segments beyond circadian niches.
• Legrand: Legrand's building systems division offers commercial lighting controls and connected building solutions across global markets. Comparable as an incumbent that can bundle lighting controls into larger building-automation projects, including circadian/tunable-white workflows.
• Lutron Electronics: Lutron is a global leader in lighting controls (dimming, scene control, automated shading) used in commercial and high-end residential environments. Comparable to the circadian-control layer of Libu's offering and increasingly relevant as control-based circadian strategies become standard in offices.

Emerging players

• Sengled: Sengled offers smart tunable-white and circadian-oriented bulbs and luminaires with a focus on accessibility and ease of deployment. Comparable as an emerging player in human-centric lighting, though more consumer/SMB-skewed and less specialized in the enterprise office segment Libu targets.
