Wbmax GmbH

What Wbmax GmbH does

Wbmax GmbH is a Frankfurt am Main-based mechanical and electrical trade contractor (TGA / Technische Gebäudeausrüstung) delivering installation services across five disciplines: heating (Heizungsanlagen), ventilation and air-conditioning (Lüftungsanlagen), sanitary installations (Sanitäre Anlagen), electrical installations (Elektroinstallationen), and fire suppression systems (Feuerlöschanlagen). The company executes multi-system installations for residential, commercial, hospitality, sports, logistics, and industrial buildings, with compliance documented across an extensive catalogue of German DIN and VdS standards. Its portfolio includes enterprise-scale projects such as ROCHE Mannheim, Omniturm Frankfurt, Nintendo Frankfurt office, Hotel FLAG Frankfurt, TEGUT logistics centre, and Stadium am Böllenfalltor in Darmstadt.

The company traces its origins to 2011 in Romania as ALTERNATIVE VECTOR TRUST (solar panel manufacturing). It expanded into HVAC/sanitary through DIVER ENERGY in 2013, established R&D subsidiaries ENERGY LOGISTIC PARK and GESPA in 2017, and began executing major German projects in Frankfurt from 2018. Headquarters relocated to Frankfurt am Main in 2020 with the service area extended to all of Germany, and a technical headquarters was added in Offenbach am Main in 2022. The company is founder-led, with Daniel-Florin Maxim serving as Managing Director (Geschäftsführer), and is registered as a private limited liability company (HRB 118542, Frankfurt am Main).

Revenue is generated entirely on a project-by-project basis via direct, relationship-driven B2B field sales, with no recurring or subscription model. Pricing is per-project scope and not publicly disclosed. Marketing relies on the website's project portfolio rather than paid digital channels. No external funding rounds, no parent company, no AI/ML capability, no app, and no API are disclosed. A material data inconsistency exists: firmographic headcount is reported as 7 while the company history page references 150 employees as of 2019, which is not reconciled in the source material and is the dominant risk signal for any quantitative extrapolation.
