KG is a German electrical engineering contractor headquartered in Köln-Ehrenfeld, founded in 1894 and now in its fourth generation of family ownership under the Kleinen family. The company plans, installs, and maintains complete electrical systems for buildings, covering medium and low voltage distribution, lighting, communications, security, IT infrastructure, and lightning protection, with work executed both as specialty subcontractor and as technical general contractor. It serves enterprise, public-sector, and healthcare clients on large-scale commercial, healthcare, education, event, retail, residential, and industrial projects, with reference clients including Deutsche Bundesbank, Vodafone, Henkel, Mercedes Benz, DHL, Hermes, Universitätsklinikum Bonn, and Kölnmesse.

The firm operates a BIM-based planning workflow using DDS-CAD with Open-BIM/IFC interoperability, alongside AutoCAD, Simaris, and Dialux, to deliver collision-free designs on complex projects. Its service portfolio is horizontally segmented across eight use cases (office, hotel, healthcare, education and research, events, retail, industry, and residential), with three revenue streams: project-based installation contracts ranging from €350K to €23.5M, recurring maintenance and technical operations, and an emerging E-Mobility line for EV charging infrastructure.

Go-to-market is enterprise field sales and competitive bidding for major construction works, supplemented by general contractor engagements. Pricing is quote-driven and project-specific, with no public price list. Annual operating performance exceeds €50M, the firm employs 350+ people across offices in Köln and Frankfurt am Main, and is prequalified under VOB, ISO 9001:2015 certified, and holds multiple DGNB/LEED/WiredScore project certifications.
