Detailed Review
The company lists these sites: FRA01 to FRA03 and the planned FRA04 and FRA05 in Frankfurt, BER01 and BER02 in Berlin, and AMS01 in Amsterdam. Its imprint names maincubes Holding & Service GmbH, Tilsiter Strasse 1 in Frankfurt, commercial register HRB 118726 at Amtsgericht Frankfurt.
The website is German first, with an English version. It states a portfolio above 400 MW of IT capacity, including sites in operation and in development.
Where retail colocation actually sits
FRA01 is a 6 MW colocation site opened in 2017, and AMS01 a 5 MW colocation and OCP Ready facility opened in 2018. FRA02 (8 MW) and BER01 (9 MW) are government-leased halls with N+1 design, and FRA03 provides 16 MW for hyperscale and HPC tenants.
The big expansion is Berlin BER02, listed at 144 to 186 MW and under construction, with FRA04 (40 MW) and FRA05 (75 MW) at planning or pipeline stage.
Public sector focus
maincubes markets secure environments for agencies and critical-infrastructure organisations, talking about data protection, data security and sovereignty at national and European level. It also offers powered shell and build-to-suit for cloud and AI providers.
Ownership statement
The company calls itself a fast-growing European provider with a German ownership structure, and its page presents the investor team of DTCP, an investment manager with offices in San Francisco, Hamburg, Frankfurt, Berlin, London, Luxembourg and Tel Aviv. Readers applying a strict ownership rule should review that page.
Limitations to Consider
Most of the pipeline is hyperscale and government capacity, and only FRA01 and AMS01 are labelled as colocation, so small tenants have few options. The site is German first. The investor manager DTCP lists a San Francisco office, and quotes are only given on request. For smaller racks in Germany, NorthC is the more natural fit.
Who Should Use maincubes
Cloud providers, AI operators and public agencies that want large German capacity in Frankfurt or Berlin from a German-owned operator.
