Kullmann Und Meinen Gmbh

What Kullmann Und Meinen Gmbh does

Kullmann und Meinen GmbH is a privately held German consulting firm headquartered in Rösrath that specializes in business advisory services for the GaLaBau (Garten- und Landschaftsbau) sector — garden, landscaping, and sports-ground construction companies. The firm was founded in 2014 by Dipl.-Ing. Jens Kullmann and Prof. Dr.-Ing. Heiko Meinen, though the principals claim nearly two decades of consulting experience in the vertical. It maintains regular contact with over 300 clients across Germany and operates with 11–50 employees.

The firm's core technology is KERplus®, a proprietary cost-accounting and planning system (Plankostenrechnung) that captures hourly rates and operational cost drivers specific to landscaping projects. KERplus® is paired with target-actual comparison (Soll-Ist-Vergleich), company valuation, risk assessment (StaRUG-aligned Risiko-Check), and INSIGHTS MDI-based employee development modules. Adjacent service lines cover strategy consulting, business lifecycle phases (founding, succession, restructuring), sustainability reporting under the DNK standard, and ERFA peer-exchange groups. Knowledge products include the IMFOKUS newsletter, a webinar series hosted on ClickMeeting, expert articles, and a published reference book. Technology integrations cited include DATEV for accounting workflows, Microsoft Teams for initial consultations, and Outlook for appointment scheduling.

Kullmann und Meinen generates revenue through project-based professional services fees, with many engagements reportedly eligible for public funding subsidies. Go-to-market is sales-led and content-driven, combining a free initial consultation via MS Teams, an extensive library of expert articles and webinars, multi-channel social media (LinkedIn, Facebook, Instagram, YouTube), industry event participation (GaLaBau trade fair), and referral-based lead generation. The firm expanded its seminar and coaching division through the January 2025 acquisition of José Flume – Beziehungsentwicklung and holds a strategic co-exhibition partnership with galawork at the GaLaBau 2026 trade fair.

Scale indicators2 records

Expansion highlights4 records

Broad incumbents

• Ebner Stolz: Large German Mittelstand-focused advisory and accounting firm offering controlling, succession and restructuring services to SMEs; represents the type of generalist incumbent that could encroach on K&M's niche if it deepens construction/trades expertise.
• RKW Hessen GmbH: German Mittelstand consulting network providing operational, strategic and HR advisory to German SMEs including trades and construction-adjacent firms — broadly comparable business model and target segment, but without GaLaBau specialisation.
• DATEV eG: Dominant German tax, accounting and ERP cooperative used by SMBs including GaLaBau customers. Functions as both an integration partner (DATEV ↔ KERplus®) and a potential platform competitor for the controlling/advisory layer in SMB construction.
• Drees & Sommer SE: Large German construction-and-real-estate consultancy delivering project and cost management. Comparable on the construction-vertical consulting axis but much larger and focused on building projects rather than landscape trades.

Others

• INSIGHTS MDI / Metaplan: Provider of INSIGHTS Discovery/MDI personality and team diagnostics used inside K&M's Mitarbeiterentwicklung engagements; comparable as a methodology/HR-psychometrics supplier rather than a direct competitor.
• Bundesverband Garten-, Landschafts- und Sportplatzbau e.V. (BGL): Federal industry association for the German GaLaBau sector; not a competitor but a strategic institutional partner (GaLaBau Company Check, industry report co-authorship) that shapes the market in which K&M operates.

Direct peers

• galawork workgroup GmbH: Software vendor specialised in the German GaLaBau industry (planning, mobile workforce, costing); co-exhibits with K&M at GaLaBau 2026 and serves overlapping SMB customers. Adjacent rather than directly competitive but the closest functional peer in the same vertical.
