What Nabiax does

Nabiax is a Madrid-headquartered colocation and hosting data center operator and the largest independent colocation provider in Spain. The company operates six data centers across three campuses — Alcalá de Henares, Julián Camarillo, and Terrassa — totaling approximately 36 MW of installed IT capacity across 28,000 sqm of white space, with a publicly stated roadmap to 100 MW. Its core products are colocation services (renting secure rack space with power, cooling, multi-fiber carrier connectivity, and 100% renewable energy supply) and managed hosting services for clients that prefer fully outsourced server operations. The technology stack is purpose-built for hyperscale and AI workloads, featuring adaptive data halls with 100% liquid cooling capability, Tier IV design and construction at ADC1, and Tier III at ADC2; the upcoming ADC3 campus is specifically positioned for hyperscale AI compute.

The business model is enterprise field sales to two distinct customer tiers: hyperscalers and large cloud providers (where the company reports hosting three of the four major cloud providers in its Madrid facilities and recent 10 MW contracts with two hyperscalers representing roughly 30% of revenue), and traditional telecommunications and enterprise customers, anchored historically by Telefónica. Revenue is generated via recurring, long-duration colocation contracts priced on power (MW/kW), space, and connectivity, with quote-based pricing tailored to each tenant's needs. The company is privately held by Aermont Capital following its November 2024 acquisition from Asterion and Telefónica, and operates through two Spanish legal entities (Digital Data Centre Bidco, S.L. and Digital DHF Iberia, S.L.U.). Sustainability credentials — including Tier IV Gold Operational Sustainability certification (the only Spanish colocation operator holding it), ISO 14001, LEED, BREEAM, and membership in the Climate Neutral Data Center Pact — are a central element of its go-to-market positioning.
