Larbig & Mortag

What Larbig & Mortag does

Larbig & Mortag is a privately held German commercial real estate brokerage operating exclusively in the Köln-Bonn-Leverkusen metropolitan area. Founded in 2008 by Managing Directors Markus Larbig and Uwe Mortag, the firm is structured across two legal entities — Larbig & Mortag Immobilien GmbH (Cologne headquarters) and Larbig & Mortag Immobilien Bonn GmbH (Bonn, est. 2013, led by Hendrik Heßlenberg) — with a third office in Leverkusen opened in 2016. The firm has self-positioned as the largest office real estate broker in Cologne since 2012 and derives revenue entirely through transaction commissions on rentals (3.0–5.0 net monthly rents, scaled by contract duration), purchases and sales (4% of notarized total purchase price), pre-emption and forward purchase rights (1%), and ancillary project development services. Customer segments span office users, logistics and industrial firms, healthcare providers (Ärzte/Praxisräume), retailers, gastronomy operators, and commercial investors, with enterprise tenants documented at AirportBusinessPark Köln.

The company's technology stack is conventional broker tooling rather than proprietary IP: a web-based property listings portal, interactive digital exposés, a free Gewerbeflächen-Kalkulator (commercial space calculator), FLOWFACT CRM for property inventory management, Matelso for call tracking, and Leadinfo for B2B IP-based lead identification. Service extensions include ESG/sustainability consulting, a rental-agreement review service (Mietvertragscheck), floor plan design (Grundrissplanung), and a curated service-partner network for relocation, furnishing, IT, and renovation. Carbon-neutral certification was achieved in 2021 through a ClimatePartner partnership. Distribution is sales-led through three physical offices and the NAI Partners Germany international network, with marketing concentrated on SEO, content, Google reviews, and local sponsorship.
