What Cyneo does

Cyneo is a French circular-economy facilitator operating a B2B marketplace and physical-infrastructure network dedicated to material reuse in the construction sector. Founded as a wholly-owned subsidiary of Bouygues Construction (capital social €500,000), the company runs La Boutique Cyneo, a two-sided e-commerce marketplace connecting suppliers of reclaimed building materials with professional buyers, charging 5% commission to community members and 10% to non-members. Catalog scope spans plumbing/sanitary, electrical/HVAC, partitions/ceilings, flooring, joinery, facades, exterior works, furniture, and ironwork, supported by Stripe-based PCI-DSS Level 1 payment processing and GDPR-compliant data handling.

Its physical layer is organized around a growing network of Technical Centers that combine warehouses, workshops, showrooms, and co-working spaces for specialist reuse SMEs. The first center opened in Vitry-sur-Seine in November 2023 (2,700 m²) and a second opened in Nantes (Saint-Aignan-Grandlieu) in January 2025 (3,500 m²), with Lille, Lyon, and Toulouse planned for 2025 and a stated target of approximately 10 centers nationally by 2027. Resident businesses include Proclus, Remake, Textifloor, Tri n Collect, and Tricycle (Vitry), and La Miroiterie du Réemploi, Gueules de Bois, Ecophon (Saint-Gobain), and CARBOROK (Nantes).

The go-to-market combines a community-membership model (Communauté Cyneo with 90+ member companies), the BOOST seller certification program, the La Circulaire industry magazine, and event/conference presence, complemented by partnerships with Valobat (EPR eco-organization for PMCB) and the BCG/2050NOW DO Tank acceleration program. Monetization relies on three streams: marketplace commissions on transactions, membership fees that confer a 50% reduction in service fees, and rental/managed-services revenue from technical-center tenants. Customer segments served include reuse material suppliers, SMEs/artisans developing circular product lines, deconstruction contractors, AMO Réemploi advisors, public-sector collectivities, and circular-economy associations across France's Île-de-France, Pays de la Loire, Hauts-de-France, Auvergne-Rhône-Alpes, and Occitanie regions.

Core offering

Cyneo operates a B2B digital marketplace and a national network of physical Technical Centers that together enable the buying, selling, reconditioning and storage of reused and reclaimed construction materials. The marketplace (La Boutique Cyneo) connects professional buyers with certified sellers of raw materials from deconstruction and ready-to-install products, while the Technical Centers provide workshops, pallet storage, showrooms, training and co-working infrastructure for companies operating in the construction reuse sector.

Product overview

Cyneo operates as a circular economy facilitator for the French construction sector, organized as a platform-plus-physical-network model. The core offering consists of La Boutique Cyneo (the digital marketplace for buying and selling reclaimed construction materials) and the Plateforme Digitale Cyneo (the matching platform connecting material suppliers and buyers). These digital platforms are supported by a network of physical Technical Centers in Vitry-sur-Seine (opened 2023), Nantes (opened 2025), and planned expansions to Lille, Lyon, and Toulouse by 2027. The company also offers the Communauté Cyneo membership program providing access to events, training, and a 50% service fee discount, and the Programme BOOST for certified sellers. The platform categories span plumbing/sanitary, electrical/HVAC, partitions/ceilings, flooring, joinery, facades, exterior/VRD, furniture, and ironwork.

Expansion highlights5 records

Direct peers

• Cycle Up: French digital platform for reused construction materials operated by the Léonard Group. Direct competitor to Cyneo, offering similar marketplace functionality and material reuse services for the French construction sector.
• Backacia: French B2B marketplace for reused construction materials, very similar in mission and offering to Cyneo. Both platforms connect suppliers and buyers of deconstruction materials, serving the same circular economy in construction niche in France.
• Bellastock: French cooperative focused on construction material reuse and circular economy. Operates similar physical infrastructure (material reuse centers) and projects, comparable to Cyneo's Technical Center model.

Broad incumbents

• Legrand: Global electrical equipment manufacturer and a publicly cited Cyneo member. Comparable as a strategic partner driving reuse of electrical equipment from deconstruction, but operates as a broad incumbent in its own product category.
• Saint-Gobain: Major French building materials multinational with circular economy initiatives (Ecophon, a Saint-Gobain brand, is a Cyneo partner at Nantes). A broad incumbent in construction materials with overlapping capabilities in sustainable and reused materials.

Emerging players

• Materials Market: UK-based marketplace for construction materials reuse. Emergent player in the same construction reuse marketplace category, with partial geographic and feature overlap with Cyneo's marketplace model.

Others

• Valobat: French state-approved eco-organization for EPR in construction products and materials (PMCB). A strategic partner of Cyneo, Valobat is comparable as an ecosystem/regulatory enabler that channels material flows toward reuse infrastructure.
• Bouygues Construction: Parent company and primary financial backer of Cyneo. Bouygues Construction is a major French construction group whose strategic priorities and project pipeline directly shape Cyneo's opportunity and resource access.

Regional players

• Matério: Belgian material library and reuse platform helping architects and builders specify reused materials. Operates in a comparable niche but in Belgium rather than France, so geographic overlap is limited.
• Rotor DC: Belgian non-profit specialized in construction and demolition material reuse. Operates a comparable model of material recovery and resale, but primarily in Belgium rather than France, making it a regional peer in the same architecture reuse space.
