📄 Editorial Review

maincubes (Est. 2012) is a European colocation and data center operator headquartered in Frankfurt am Main. The company focuses entirely on data center capacity rather than classic retail hosting, so the offer is aimed at cloud and AI providers, large enterprises, platforms, and public-sector organizations that need secure space for their own hardware rather than shared web hosting or managed VPS.

Their footprint currently spans data centers around Amsterdam, Berlin and the Frankfurt metro region in Germany, with additional corporate presence in the Netherlands. Existing facilities (AMS01, FRA01, FRA02, BER01) are fully built and in operation, while FRA03, FRA04 and BER02 ("mainhub Berlin" campus) extend that capacity significantly over the next few years. Across these locations the company pushes a consistent mix of high availability, high power density and sustainability – including a strong focus on renewable energy and waste-heat reuse.
The core "product" is colocation. Instead of shared hosting or managed servers, customers rent racks, private cages, or entire private suites and bring their own hardware (or work with integrator partners). The colocation stack is clearly structured:

• Racks – standard colocation racks, with the option to use racks provided by the data center or bring your own.
• Private Cage – fenced-off areas within shared rooms for higher physical separation.
• Private Suite – dedicated halls or suites tailored to a single customer’s design and density needs.
• Capacity & Power – high-density power per rack (up to ~20 kW in some sites) and room-level power in the multi-megawatt range.
• Network & Services – cross-connects to carriers and cloud on-ramps, remote hands, office and meet-me rooms, and 24/7/365 access with on-site personnel.

For anyone looking for shared web hosting, VPS plans, or dedicated servers, this is not the right provider; the business model sits squarely at data-center and infrastructure level.
From an infrastructure perspective, the portfolio is quite differentiated:

• FRA01 (Frankfurt-01) – a multi-tenant colocation facility with about 4,200 m2 white space and 6 MW IT capacity. It offers 100% SLA availability, a PUE around 1.3, Kyoto-style free-air cooling, and is powered exclusively by green electricity. The site is DE-CIX enabled, with a long list of carriers, and has a full set of certifications (EMAS, ISO 27001/9001/14001/50001, DIN EN 50600 including VK3, SOC 1/2, ÖkoPLUS). Architecturally, it’s a fairly mature site, opened in 2017 and awarded for its data-center design.
• FRA02 (Frankfurt-02) – a newer single-tenant facility in Schwalbach with around 4,700 m2 white space and 7.3 MW IT capacity, again with 100% SLA availability and a PUE below 1.3. Cooling is based on an innovative cooling wall concept designed for high density and future liquid cooling, while a rotating UPS system and IP-bus architecture support very high availability (parts of the design even reach VK4 levels). Waste heat is fed into the municipal heating network, turning the data center into a local heat source instead of just an energy consumer. The entire site is currently dedicated to a public-sector tenant, which tells a lot about the security and compliance profile.
• FRA03 – a carrier-neutral colocation project near Frankfurt that is built as an AI-ready, HPC-capable campus. It is planned as a 16 MW-class facility with strong focus on renewable energy, liquid-cooling options and waste-heat reuse. The company explicitly underlines a 100% uptime guarantee (SLA) once FRA03 is in full operation, with phased construction from 2024 through 2026/27.
• FRA04 – a large hyperscaler-focused data-center campus in the Frankfurt region with 60 MW committed power and expansion potential far beyond that. Design targets include PUE values at or below 1.2, full green-power sourcing and integrated waste-heat concepts. FRA04 is clearly positioned for cloud and AI platforms that need very large contiguous capacity.
• AMS01 (Amsterdam-01) – a multi-tenant colocation site with 4,400 m2 white space and 4.7 MW IT capacity. It carries 100% SLA availability, a PUE around 1.6, closed-loop water-based cooling, and is powered by green electricity. The site is certified as an OCP Ready facility through the Open Compute Project program, tuned specifically for Open Compute hardware and high-density racks up to ~20 kW. Carrier choice is broad and carrier-neutral, with many international backbone and metro providers on-site.
• BER01 (Berlin-01) – an 8.2 MW facility in the Berlin region designed for single-tenant use by a German federal ministry. It combines 100% SLA availability, PUE at or below 1.26, and very strict physical and logical security, including multi-layered access control and on-site security staff.
• BER02 / "mainhub Berlin" – a larger campus project in Nauen (near Berlin) that will add well over 100 MW of capacity for hyperscale and AI workloads over the next years, again with very strong focus on energy efficiency and sustainable operations.

The whole platform is wrapped in a strong sustainability and ESG narrative: renewable electricity at all operational sites, EMAS environmental certification, ISO 14001 and ISO 50001 for energy and environmental management, climate-neutral initiatives (ÖkoPLUS), as well as extensive work on waste-heat reuse and local partnerships with municipalities. For customers with their own ESG targets, that is a substantial advantage compared with more conventional colocation players.

Instead of trying to do everything in-house, the company offers a service marketplace where partners contribute additional layers such as managed services, cloud connectivity, security offerings or storage platforms that can be physically deployed inside the maincubes facilities. Combined with the rack / cage / suite mix and flexible power provisioning, this gives enterprises and cloud players the option to build quite complex infrastructure stacks within the same footprint.

On the corporate side, the company was founded in 2012 and is led by CEO Oliver Menzel together with an experienced management team based in Frankfurt. With German ownership and all facilities located in the EU, they position themselves strongly around European data sovereignty, strict adherence to EU data-protection rules and a "made in Europe" infrastructure story.
