What OSSO B.V. does
OSSO B.V. is a privately held Dutch managed-infrastructure operator founded in 2005 and headquartered in Groningen, Netherlands, with a team of approximately nine to ten people. The company specializes in open source hosting, network, and cloud infrastructure, integrating network engineering, system engineering, and software development (DevOps, NetDev, SysOps, SecOps) into a single managed-services portfolio. Its product surface comprises three core, interdependent pillars: Specialized Hosting (high-availability, multi-site hosting with 10G/25G/100G connectivity), 24/7 Operations (incident response, active monitoring, and Site Reliability Engineering), and Managed Kubernetes (cluster operations with developer support, including GPU deployments via HAMi and vLLM for AI workloads).
Underlying the services is a proprietary technical stack anchored by OSSO's independent AS43366 IP network, an internal closso.network 3-spine-leaf fabric with 100G links, and an osso.network edge with Nokia 7750 SR-1 routers delivering 100G IP transit and direct 100G links to Amsterdam. The company operates MinIO-based petabyte-scale object storage, native IPv6, Cilium-based Kubernetes networking with NetworkPolicies, and a portfolio of in-house audit and CVE-management tools (natsomatch, subnact, auditif, GoCollect, vetted-modprobe). Security and compliance are formalized through DNV-certified ISO/IEC 27001:2022 and NEN 7510-1:2017 Information Security Management Systems, both valid through 2026-11-27, with the latter positioning OSSO for healthcare category 3/4 environments.
OSSO's revenue model is custom-tailored managed services, with no public pricing. The go-to-market is direct, enterprise-grade field sales via named points of contact (e.g., Herman Bos for sales, Walter Doekes as DPO), supplemented by community-led marketing through CNCF and Linux Foundation silver memberships, technical blogging, GitHub open source publishing, and conference participation. Primary customer segments are ISPs, SaaS/cloud services, and tech startups requiring high-availability infrastructure, with an additional healthcare vertical served under NEN 7510 and a UK geothermal/construction partnership with ProMinent UK and Ireland valued at over £2 million. Markets served are concentrated in the Netherlands, with broader European reach implied by infrastructure scale and partnerships.

OSSO B.V. competitors and assessment
Company assessmentBroad incumbents
- Scaleway: Major European cloud provider owned by Iliad, offering bare-metal, managed Kubernetes, object storage, and AI/GPU instances across EU regions. Comparable as sovereignty-first European alternative but at significantly larger scale and broader product portfolio.
- Leaseweb: Large global hosting and cloud provider founded in the Netherlands with extensive data-center footprint across Europe, Asia, and the US. Offers managed hosting, public/private cloud, and network services that overlap OSSO's portfolio at much larger scale and broader geographic reach.
Direct peers
- BIT BV: Long-established Dutch ISP and managed hosting provider operating its own backbone and data centers, serving similar enterprise and SME customers in the Netherlands. Comparable in independent-infrastructure model and target customer profile.
- Cyso Hosting: Dutch managed hosting and cloud provider headquartered in the Netherlands, offering managed Kubernetes, private cloud, and compliance-ready hosting. Competes head-on with OSSO in the Dutch ISP/SaaS/healthcare infrastructure market.
- NFOrce Internet Services: Dutch ISP and hosting company operating its own network and data centers, serving enterprise and smaller customers in the Netherlands with comparable dedicated servers, colocation, and managed services.
- Civo: UK-headquartered managed Kubernetes and cloud provider focused on developer-friendly, Kubernetes-first infrastructure. Comparable in managed Kubernetes positioning and open-source community orientation, though at materially larger scale.
- UpCloud: Finnish cloud infrastructure provider emphasizing high-performance cloud servers and managed services in Europe. Comparable as European-rooted IaaS alternative with focus on performance and EU data residency.
- Hetzner: German managed hosting and cloud provider offering dedicated servers, cloud IaaS, and storage built on a similar open-source-friendly philosophy. Closest direct peer in terms of independent infrastructure ownership and developer-centric managed hosting for European ISPs, SaaS firms, and startups.
Regional players
- Greenhost: Sustainable Dutch managed hosting and cloud provider focused on privacy-conscious, EU-sovereignty customers. Smaller in scale but philosophically aligned and competes for similar open-source-friendly, Dutch-SME/NGO customer segments.
- SURF (SURFsara/SURFcumulus): Dutch collaborative organization for education and research ICT, providing cloud and HPC infrastructure for Dutch academic and research institutions. Comparable in operating large-scale Netherlands-rooted infrastructure for regulated/compliance-sensitive customers, though focused on research rather than commercial ISPs/SaaS.
