What Nextiim does
Nextiim SAS is a French building technology company founded in 2018 and headquartered in Guyancourt, operating as a subsidiary of Groupe BTP Consultants. The company combines GTB (Gestion Technique du Bâtiment) integration services with its proprietary Sextant digital twin platform, which provides real-time technical and energy management of tertiary and industrial buildings. Nextiim's Sextant platform aggregates time-series sensor data, energy and water consumption, BIM/3D scans, georeferenced equipment inventories, and centralized document management (dataroom), and supports interoperability with existing building automation protocols including KNX, BACnet/IP, Modbus, and LonWorks.
The company's services span the full GTB lifecycle: audit (including Décret BACS and Décret Tertiaire compliance), design, installation, renovation, and ongoing maintenance, plus GTB Light solutions for smaller buildings, counting plans, and CEE financing support. Quantified outcomes cited include up to 45% heating energy savings and 55% lighting energy savings with Class A GTB, alongside 3–5 year ROI typical payback periods. Nextiim holds KNX Advanced certification and is a member of Lonmark Francophone, the Collège des intégrateurs KNX, and AICN/APROMA.
Nextiim sells exclusively through a direct enterprise field-sales motion via five regional agencies across France (Ile-de-France, Rhône-Alpes, Occitanie, Nouvelle-Aquitaine, PACA). Named customers include SEGRO, Société de la Tour Eiffel, CMA CGM, RATP, Nokia, Primonial, Loxam, SEFAL Property, and Accessite, spanning logistics, real estate, transportation, retail, and equipment rental. Revenue is generated through project-based professional services contracts combined with Sextant deployment and recurring platform subscriptions; pricing is quote-based and not publicly disclosed.
