NEXEREN

What NEXEREN does

NEXEREN is a French datacenter colocation operator headquartered in Rillieux-la-Pape (near Lyon) and operating as a wholly-owned subsidiary (SASU) of XEFI Group, a private French IT services conglomerate founded in 1997 with approximately 900–1,000 employees. Originally created in 2013 under the name SHD (Solutions d'Hébergement Durable) and rebranded to NEXEREN in 2023, the company runs a network of 6 interconnected datacenters across the Auvergne-Rhône-Alpes and Occitanie regions (CV1, CV2, CBZ, RVS, MPL operational; YTA planned for 2026), totaling 694 bays and ~2MW of IT power capacity, with PUE ratios of 1.13–1.24 that place it among the most energy-efficient operators in France.

The company's core offering is professional colocation: customers house their own servers and IT equipment in NEXEREN's facilities, retaining ownership while benefiting from redundant power (2N architecture), precision cooling, physical security, and carrier-neutral connectivity. Three service tiers — Standard (ISO 27001 + HDS), Avancé (Tier III with concurrent maintenance), and Elite (Tier IV with fault tolerance) — address non-critical to mission-critical workloads. Connectivity services include Wave (dedicated optical wavelength), LAN-to-LAN Layer 2 interconnection, Dark Fiber, Transit IP, and inter-datacenter transport over a dual-fiber ring. Smart Hands / Gestes de Proximité provides 24/7 on-site physical interventions, and SKERA — a cloud-engineering sub-brand — develops custom cloud applications under the same campus. NEXEREN is the only French operator holding dual Tier III and Tier IV Design & Facility certifications from the Uptime Institute, holds HDS certification for hosting French healthcare data, and positions its infrastructure as sovereign French hosting not subject to U.S. CLOUD Act or FISA extraterritorial legislation, powered by 100% renewable energy.

The business model is predominantly subscription-based, recurring revenue from multi-year colocation and connectivity contracts, supplemented by Smart Hands professional services. NEXEREN employs a direct enterprise sales motion — dedicated account contacts, 24-hour response time, personalized proposals, and site visits — targeting healthcare providers, enterprises with critical applications, HPC/AI/GPU computing customers, public sector entities, and SMEs via XEFI Group's 100+ branch network. Pricing is quote-based and not publicly disclosed. No revenue figure is publicly available; the company is privately held with no external funding rounds identified, and growth is funded through parent-company balance sheet capacity.
