What Sydev does

Sydev is a French software publisher and integrator specializing in SaaS management solutions for the construction and building trades (BTP), headquartered in Échirolles near Grenoble. Founded in 1997, the company has built an interconnected portfolio of seven core products covering the full construction lifecycle: OPTIMA and PROGAP for cost estimation and price studies, Tarifeo and TAMZAG for pricing data and procurement, SESAME for mobile site and intervention management, and BATEAM and METEOR for web-based ERP. Its technology stack is built on SaaS architecture hosted on Microsoft Azure with daily automated pricing updates via EDI/API connections to 650+ supplier catalogs containing over 10 million product references.

The company operates a publisher-integrator business model, combining SaaS subscriptions with professional services delivered through its SIP (Sydev Ingénierie de Projet) methodology and QUALIOPI-certified training. Go-to-market is primarily direct enterprise sales supplemented by specialized reseller partners and a manufacturer/supplier ecosystem accessed through its "Espace partenaires." Sydev serves approximately 2,000 clients and 15,000+ users across SMEs, mid-market firms (ETIs), and large construction groups including Vinci, Fayat, Spie, Léon Grosse, and Derichebourg. Pricing is quote-based and not publicly disclosed, with annual billing cycles tailored to enterprise requirements.

Since 2023, Sydev has pursued an aggressive consolidation strategy, acquiring Logiweb (Bateam ERP, 2023), BS2i (Tarifeo pricing database, 2025), and M&C3i (Progap, 2025), the latter earning the CFNews "Meilleure croissance externe – Tech" award. Turenne Groupe, a French small-cap private equity firm, entered the capital in July 2024 to back further organic and external growth. The company employs approximately 80 people and is structured as a "société à mission" (mission-driven company) since 2023.
