KOLO Solutions

What KOLO Solutions does

KOLO Solutions (legal entity CMNI II Bon JV Sàrl, Luxembourg) is a private colocation and digital infrastructure platform operating 12 data centers across Sweden, Denmark, and the Netherlands. The company was formed in 2023 by combining Serverius (Netherlands) and Fuzion (Denmark) under the backing of CapMan Infra, and expanded into Sweden in 2025 through the acquisition of three Eco Data Center sites. Kolo positions itself as a 100% European-owned sovereign operator, explicitly emphasizing data residency, NIS2/GDPR compliance, and the absence of foreign ownership — a positioning aimed at regulated buyers in finance, government, healthcare, and EU-focused SaaS.

The platform's core technical differentiators are AI-ready infrastructure with high-density rack support (50+ kW per rack, liquid cooling), carrier-neutral metro-edge interconnection via the Kolo Konnect fabric, direct cloud on-ramps to AWS, Azure, and Google Cloud, and specialized offerings including EMP-protected colocation (Faraday-enclosed racks to full hardened data halls), integrated DDoS protection up to 3 Tbps, NOC-as-a-Service, and a Lease-to-Own hardware financing program. Sustainability is a substantive element: 100% renewable energy at major sites and up to 65% annual free cooling at the Piteå Arctic site deliver a real cost-and-carbon advantage, complemented by the NADIKI research partnership with University of Stuttgart for real-time AI carbon-footprint measurement.

Commercially, Kolo operates a sales-led direct enterprise motion with pre-sales engineering support, supplemented by a Partner Program covering referral, reseller, and white-label arrangements with system integrators, technology providers, IT resellers, and real estate brokers. Revenue is generated primarily through recurring colocation subscriptions, connectivity/bandwidth fees, and premium security and managed services, with named long-tenured customers across hosting, software, mobility, and IT services. The company is led by CEO Bastiaan Fremouw (ex-Google), CFO Philippe Rechsteiner (ex-Etix Everywhere, Vantage Data Centers, DataQube), and Head of People & Culture Sophie Rebischung.

Others

• Digital Realty: Largest global data center REIT with extensive European footprint and major presence in Frankfurt, Amsterdam, Dublin, and Paris. Comparable as a broad incumbent in multi-tenant colocation with overlapping Dutch presence, but operates as a diversified global platform rather than Kolo's sovereign Nordic specialization.

Broad incumbents

• Iron Mountain Data Centers: Global data center operator with expanding European footprint (e.g., Amsterdam, Frankfurt) targeting enterprise, government, and regulated industries. Comparable as a broad colocation incumbent with similar focus on compliance, security, and government customers, but with a much larger global portfolio.
• Vantage Data Centers: Global hyperscale data center operator with expanding European platform (Frankfurt, Berlin, Cardiff, Amsterdam) targeting AI and cloud customers. Comparable as a broad incumbent investing in high-density AI-ready capacity in Europe, but focused on wholesale hyperscale rather than Kolo's retail/SMB-inclusive model.
