Le Trèfle

What Le Trèfle does

Le Trèfle (legal entity: Groupe Le Trèfle) is a privately held French coworking and flexible workspace operator founded in 2013 by Bertrand Rosé, who serves as president alongside director Delphine Decout. The company operates four physical locations across the Greater Paris region and Lyon: Boulogne-Billancourt Marcel Sembat (headquarters, featuring the Le Trifolium event venue and L'Eden restaurant), Boulogne-Billancourt Pont de Sèvres, Issy-les-Moulineaux Corentin Celton (~400 m², 70 workstations, plus a 1,300 m² accelerator-dedicated expansion), and Lyon Jules Courmont (a 160 m² former workshop on the Presqu'île). Its customer base is a horizontal mix of entrepreneurs, freelancers, SMEs, and accelerator programs, with tenants drawn substantially through the Grand Paris Seine Ouest Synintra platform (80,000+ entrepreneurs) and the Booster de So Digital startup accelerator.

The company's core service lines are coworking day passes and monthly subscriptions, private offices for 1-8+ persons, hourly meeting and conference rooms, modular event space, business domiciliation (registered address and mail forwarding), and on-site F&B through Green Sur Mesure (Poke bowls) and L'Eden (bistronomic). The technology layer is intentionally thin: booking and member management run on trefle.cowork.io, a third-party coworking platform, with no proprietary AI, data, or integration layer disclosed. Fiber internet (WiFi plus wired RJ45) is positioned as a performance differentiator.

The revenue model is a mix of recurring subscriptions (coworking memberships, private offices, domiciliation) and usage-based fees (meeting rooms, event space, restaurant transactions). Published pricing ranges from €20 HT for a single day pass to €2,520 HT/month for an 8-person private office, with meeting rooms at €37-€73 HT/hour and event space at €200 HT/hour. The go-to-market is direct-to-consumer with self-serve booking supplemented by inbound inquiry handling; ecosystem partnerships with GPSO, CCI Paris Hauts-de-Seine, and Récréatio provide accelerator-driven deal flow. No external institutional funding, revenue, or ARR has been disclosed, and the company is founder-controlled with an employee headcount of 1-10.

Direct peers

• Deskopolitan: Paris-based coworking and private office operator targeting start-ups, scale-ups and SMEs. Closely comparable to Le Trèfle in product mix (coworking, private offices, meeting rooms, events) and customer segment across the Île-de-France market.
• Bureau & Co / The Bureau: French flexible workspace operator with coworking, private offices, meeting rooms and event venues across major French cities. Direct competitor on product breadth and SME/enterprise customer base.
• Hubblo: French coworking and shared-office operator founded in Lyon, with Paris presence. Comparable to Le Trèfle as a regional multi-site coworking brand serving entrepreneurs, freelancers and SMEs.
• Wojo (formerly Multiburo): Major French flexible-workspace operator with a multi-site network across Paris and other French cities. Closest direct competitor to Le Trèfle, offering the same coworking-plus-private-office-plus-meeting-room stack with a similar SME and start-up customer base.
• Morning Coworking: French coworking chain with locations across multiple French cities, including Paris. Direct peer given the similar coworking-plus-domaine model, multi-site footprint and SME/start-up targeting.
• Worklib: Paris-based coworking and private office operator. Closely comparable to Le Trèfle on workspace formats, geographical targeting and entrepreneur/freelancer customer segment.
• Hiptown: French coworking and flexible-workspace brand operating several Parisian locations. Comparable product mix and customer profile (entrepreneurs, small teams, SMEs), competing directly in the same west-Paris / Île-de-France micro-markets as Le Trèfle.

Emerging players

• Station F: Paris-based mega-incubator/start-up campus. Not a direct coworking operator but a comparable ecosystem player; competes for the same early-stage entrepreneur customer base and works with overlapping partners (Grand Paris ecosystem, accelerator programs).

Broad incumbents

• WeWork: Global flexible-workspace giant with significant Paris presence. Competes with Le Trèfle for SME, start-up and enterprise occupancy in the same Paris geographies but at much larger scale and broader product scope.
• IWG (Regus / Spaces / HQ): World's largest flexible-workspace operator (Regus, Spaces, HQ, Signature). Overlaps with Le Trèfle across coworking, private offices and meeting rooms, but operates a vastly broader portfolio aimed at a wider corporate customer base.
