What Cloud&Heat Technologies does
Cloud&Heat Technologies GmbH is a Dresden-based open-source cloud service and technology provider founded in 2011, operating energy-efficient data centers with liquid cooling and serving DACH-region customers from approximately 75 employees. Its portfolio spans three product lines: Cloud Services (Managed Kubernetes, Infrastructure-as-a-Service including Compute, Object/Block Storage and GPU-as-a-Service, and Cloud Consulting), On-Premises Cloud Infrastructures (proprietary OpenStack and Kubernetes distributions branded Patron and Compass; Proxmox-based Arcanist; and appliances Atlas, Titan and Runestone), and Energy-Efficient Data Centers (liquid cooling solutions, consulting, and two-day training courses priced at €1,620 per person). Underlying technology is built on OpenStack, Kubernetes, and Proxmox VE open-source stacks, with Python, Bash, Go, Ansible and Terraform in the engineering toolkit.
The company monetizes through a hybrid model combining usage-based public cloud billing (monthly invoicing by the 15th of the following month for preceding calendar month), managed-service contracts for Kubernetes and private cloud (6-week termination), quote-based hardware appliance sales, and professional services for consulting and training. Go-to-market is multi-channel: direct enterprise sales via website/phone, channel partnerships (envia TEL for Managed Kubernetes in Leipzig; Proxmox Silver Partner status), co-selling with strategic partners such as STACKIT, and a self-service customer portal for public cloud. Customer segments include mid-market and large enterprises pursuing digital sovereignty, public-sector and critical-infrastructure operators, aerospace and research organizations (via the ESA-funded KATESIP project), and regional SMEs. Strategic positioning centers on European digital sovereignty (certified SCS-compatible IaaS as of May 2026, ISO/IEC 27001:2022 and ISO 9001:2015), open-source transparency as an alternative to US hyperscalers, and sustainability through liquid-cooled, energy-efficient infrastructure. The company is privately held with disclosed founder/management ownership, raised approximately $17.9M across funding rounds from 2013-2018 (none publicly disclosed thereafter), and is led by CEO Nicolas Röhrs alongside co-founder/CTO Jens Struckmeier.

Cloud&Heat Technologies competitors and assessment
Company assessmentDirect peers
- STACKIT: Schwarz Group's European sovereign cloud built on OpenStack; a direct competitor to Cloud&Heat's IaaS and a strategic partner on joint European cloud initiatives, targeting the same sovereignty-driven DACH enterprise and mid-market buyers.
- Hetzner: German cloud and dedicated server provider with strong price-performance reputation in DACH. Competes head-to-head with Cloud&Heat for mid-market compute, storage, and managed hosting workloads.
- Plusserver (Plusnet): German managed cloud provider offering public, private, and hybrid cloud on OpenStack and VMware stacks. Closely comparable to Cloud&Heat in customer segment (DACH mid-market/enterprise) and managed-service-led model.
- SysEleven: Berlin-based managed cloud provider specializing in OpenStack, Kubernetes (MetaKube), and sovereign DACH cloud services. Direct competitor on platform stack and customer profile, including managed Kubernetes and DGF-certified cloud.
Broad incumbents
- IONOS: Large European cloud and hosting provider offering IaaS, managed services, and dedicated servers. Competes with Cloud&Heat in DACH SMB and mid-market cloud, with significantly broader product breadth and scale.
- OVHcloud: Major European hyperscale alternative with owned data centers across multiple regions. Overlaps with Cloud&Heat on IaaS, dedicated servers, and sovereignty positioning, but at a much larger global scale.
- T-Systems (Open Telekom Cloud): Deutsche Telekom's sovereign cloud, built on OpenStack. Direct competitor for public-sector, regulated, and large-enterprise workloads in Germany, leveraging the parent's balance sheet and customer base.
Regional players
- Scaleway: French European cloud provider with owned data centers, GPU instances, and IaaS. Comparable in sovereignty/European-cloud positioning and GPU-as-a-Service, primarily serving France and broader EU rather than DACH.
- Exoscale: Swiss/European IaaS provider offering compute, storage, and managed Kubernetes with strong data-residency and sustainability positioning. Comparable in European-sovereignty and managed Kubernetes value proposition.
Others
- Proxmox Server Solutions: Vendor of Proxmox VE virtualization platform. Cloud&Heat is a Silver Partner, so direct competition is limited, but Proxmox-based managed service offerings overlap architecturally with Cloud&Heat's Arcanist product line.
