What Teractem does

Teractem is a French mixed-economy urban development operator (SEM — Société d'Économie Mixte) headquartered in Annecy, Haute-Savoie, founded in 1959 to serve public-interest missions on behalf of local and regional government authorities. The company designs, plans, and delivers integrated urban development projects including eco-districts, affordable and freehold housing, healthcare facilities (maisons de santé and pôles médico-sociaux), economic zones, public equipment, and renewable energy infrastructure across the Haute-Savoie department. Its client base spans municipalities (communes), inter-municipal authorities (Grand Annecy, Annemasse Agglo, CCG, CCUR), the Conseil Départemental de Haute-Savoie, social housing operators (Haute-Savoie Habitat, Halpades, Foncière Logement), private developers (Vinci Immobilier, Linkcity, Marignan), and end-buyers purchasing through the teractem-immobilier.fr direct sales platform.

Teractem's revenue is generated primarily through public procurement commissions (concessions d'aménagement, mandats de maîtrise d'ouvrage) with development margins and project management fees, supplemented by direct real estate sales of residential, tertiary, and commercial programs. The company also operates renewable energy subsidiaries — Solaire des Alpes and Énergies Renouvelables des Alpes — that invest in and operate photovoltaic installations. Notable proprietary technology includes the Smart Grid Thermique at the Pré Billy eco-district: 50 geothermal probes at 200m depth enabling inter-seasonal heat/cold storage, integrated with on-site photovoltaic solar panels, described as the first fully decarbonized heating and cooling network in Haute-Savoie. The company also deploys circular economy practices through the VADEME Interreg France-Suisse project for on-site reuse of excavated and demolished materials.

Distribution is dual-channel: B2G direct engagement via public procurement processes and long-term institutional relationships, plus B2C/B2B direct property sales through the branded teractem-immobilier.fr platform. Marketing relies on the company's actualités news section, regional press coverage (Dauphiné Libéré, TV8 Mont Blanc), the annual Forum des Collectivités Territoriales trade event, and YouTube video content. The company is governed by President Lionel Tardy and Director General André Barbon, with no parent company, no external funding rounds, and no disclosed revenue or valuation.

Revenue model

1. Urban development and planning fees: Teractem earns fees as mandataire or aménageur commissioned by municipalities and inter-municipal authorities (collectivités) to plan, procure, and oversee urban development projects (ZAC, concessions). Revenue is generated through development margins on land development and project management services.
2. Real estate development and sales: Through its teractem-immobilier.fr platform, Teractem develops and sells residential apartments, townhouses, commercial premises, office space, and healthcare premises directly to end-buyers (individuals, social housing providers, businesses). Revenue is generated from property sales and development margins.
3. Renewable energy infrastructure: Through its subsidiary Solaire des Alpes (Solaire des Alpes), Teractem invests in and operates photovoltaic solar installations on buildings and infrastructure (e.g., Saint-Gervais patinoire extension). Revenue derives from energy production and feed-in tariffs.
4. Subsidiary services — energy, investment, and specialized operations: Teractem operates through subsidiaries including Solaire des Alpes (renewable energy investment), and likely others referenced under 'Nos filiales'. These entities develop and operate energy projects and provide specialized services under the Teractem umbrella.

Broad incumbents

• EPA Paris-Saclay: EPA Paris-Saclay is a public development establishment overseeing large-scale urban and scientific-cluster'aménagement south of Paris — a larger, state-backed peer operating with comparable eco-district and infrastructure delivery mandates.
• Icade: Icade is a CDC-subsidiary real estate company covering offices, healthcare property, and residential — overlapping with Teractem's tertiary (Iloa), healthcare (Maisons de Santé) and residential segments at greater scale and national reach.
• Bouygues Immobilier: Bouygues Immobilier is a major national French residential and mixed-use developer, competing for the same developer slots inside Teractem-planned districts (e.g., Origami / Marignan, Arborea / Priams) and on free-market programs across the region.
• Nexity: Nexity is France's largest private real estate developer, active in residential, commercial, and serviced-property development nationwide — competing for many of the same developer competitions (e.g., Origami, Le CAELO) that Teractem orchestrates within its ZACs.
• Vinci Immobilier: Vinci Immobilier is the real estate arm of the Vinci group and a national-scale developer of residential and mixed-use programs — already a partner of Teractem at Chavanod (Le CAELO) and a competitor for prime land opportunities in the Alpine corridor.

Direct peers

• Epora: Epora is the SEM for the Rhône département, performing public-interest urban development, brownfield requalification, and eco-district delivery — directly mirroring Teractem's SEM model and'aménagement concession activity in Haute-Savoie.
• SADEV: SADEV is a mixed-economy urban development operator in Brittany, running ZACs and economic zones under public concession mandates — a near-perfect structural twin of Teractem in a different French territory.
• SOLEAM: SOLEAM is the Marseille-area SEM carrying out urban renewal, eco-district, and public-facility operations under concession from local collectivités, paralleling Teractem's full-stack mission in Haute-Savoie.

Others
