What Conapto Holding does
Conapto Holding AB (Publ.) is a Swedish data center colocation operator headquartered in Stockholm, publicly listed on Nasdaq Stockholm since August 2025 and majority-owned by the pan-European infrastructure fund Marguerite II since 2021. The company operates four purpose-built data centers in the Stockholm metropolitan area — STHLM 1 City, STHLM 2 South, STHLM 3 North, and STHLM 4 South — with a fifth facility, STHLM 5 Nord in Sollentuna, currently under construction and targeted for completion in summer 2027. Stockholm 4 South alone anchors 5,200 m² of computer room space and 24-28 MW of power, with the most recent 8 MW expansion (delivered via an Ellevio energy partnership) coming online January 1, 2026.
The core product is secure, climate-responsible colocation with guaranteed 100% uptime on power and cooling since December 2000, layered with multiple recurring revenue streams including CloudConnect (private links to AWS, Azure, Google Cloud, Oracle Cloud, IBM Cloud), Interconnect (cross-connects and Netnod IX peering), Workplace Recovery, Data Recovery, Intelligent Hands (on-site technical support), and Secure Destruction (hardware recycling via Moreco/Stena Recycling). Technology differentiation centers on high-density, AI-ready infrastructure — air cooling (1.5 MW), direct-to-chip liquid cooling (3.6 MW), and immersion cooling (1 MW) — with up to 600 kW per rack, heat reuse to district heating networks, and dynamic grid support via connection to Svenska Kraftnät's balance reserve. Conapto was the first European operator to achieve OCP Ready V2 for Hyperscale certification and holds ISO 27001, ISO 14001, ISO 50001, PCI-DSS Level 1 Supplier, and SOC 1 Type 2 compliance.
The go-to-market is enterprise field sales led by CCO Stefan Nilsson, targeting four primary segments: large Swedish enterprises (Lantmännen, ICA, STIM, Strukton, Unit 4), managed service providers, hyperscalers and AI companies (CoreWeave, CUDO Compute), and cloud service users. Pricing is quote-based and subscription-recurring with multi-year flexibility and no binding lock-in periods — a deliberate positioning against hyperscale contracts to serve enterprises that prize optionality. The company pairs 100% renewable wind power with among the lowest electricity costs in the EU as a structural cost and ESG advantage, and is expanding its footprint and hyperscaler tenant base aggressively across 2025-2027.
