Lehmann Consult GmbH & Co. KG

What Lehmann Consult GmbH & Co. KG does

Lehmann Consult GmbH & Co. KG is a German technical-economic building and real estate consulting firm founded in 2003 and headquartered in Biberach, with branch offices in Köln and Kronberg/Rhein-Main, plus service delivery into Austria and Switzerland. The firm operates as a generalist advisor across the full real estate lifecycle through five service pillars: Analyse (technical and ESG due diligence, certification consulting), Konzept (feasibility, BIM management, value engineering, planning), Umsetzung (project management and construction supervision), Betrieb (modernization, operational optimization), and a cross-cutting Nachhaltigkeit pillar covering DGNB/BREEAM/LEED certification, CRREM decarbonization pathways, and EU Taxonomy verification. Revenue is generated through project-based professional services fees on engagements with institutional real estate investors, DAX-grade corporates, and public-sector clients; the firm cites 1,150+ completed projects, 10 billion EUR in managed transaction volume, and 9.30 billion EUR in managed construction volume.

The company is structured as a GmbH & Co. KG (limited partnership) with founder Oliver Lehmann serving as Managing Director and owner, and Lehmann Consult Beteiligungs GmbH as the personally liable general partner. There is no external institutional investment, no M&A activity, and no public listing. GTM motion is sales-led, relying on personal consultation, reference discussions, a content-marketing website, and LinkedIn presence rather than paid demand generation. Customer concentration is moderate, with named enterprise relationships including AXA, BASF, Boehringer Ingelheim, Bosch, DEKA, Deutsche Bahn, Union Investment, Vonovia, ZEISS, Zurich Insurance, PATRIZIA, KGAL, UniCredit, and federal authorities across eight vertical segments (hotels, residential, retail, office, logistics, industrial, healthcare, public buildings).

The firm holds no proprietary software platform, offers no API, and discloses no AI/ML capability; technical differentiation rests on interdisciplinary teams of engineers, architects, technicians, and lawyers holding certifications such as DVP-ZERT Projektsteuerer, DVP-ZERT BIM Manager, Qual. Vergabeberater (BIngK), and DGNB Registered Professional/Auditor. Pricing is project-specific and quote-based; disclosed salary benchmarks (Trainee 48-54k EUR, Vergabemanager 48-78k EUR) and the absence of published standard pricing are consistent with a German Mittelstand services firm of roughly 50-150 professionals.
