Green Mine Wirtschaftsprüfungsgesellschaft

What Green Mine Wirtschaftsprüfungsgesellschaft does

Green Mine Wirtschaftsprüfungsgesellschaft GmbH is a privately-held German auditing and consulting firm headquartered in Essen, founded in 2022 by three partners with combined credentials spanning 20-30 years of Big-4 audit experience and 27 years of corporate experience at DAX40 companies. The firm operates as a registered Wirtschaftsprüfungsgesellschaft (WPK-Registernr: 151268600) structured around three service pillars: Accounting & Reporting Advisory (IFRS/HGB, transaction accounting, technical accounting, bookkeeping and financial statement preparation), Sustainability (CSRD/ESRS-compliant reporting, materiality analysis, GHG accounting, ESG ratings, sustainability strategy), and Risk & Controls (risk management systems, ICFR/ICSR, internal audit, process efficiency in SAP and Microsoft BC D365 environments).

The firm sells partner-led advisory and interim staffing engagements to capital market-oriented companies and owner-managed medium-sized enterprises in German-speaking markets, with no software product, public pricing, or disclosed revenue. Distribution is direct and referral-driven, supplemented by content marketing on the firm's website and partner LinkedIn profiles. Customers engage Green Mine for regulatory-complex work including IFRS implementations, IPO readiness, SPAC transactions, CSRD transformation, and ESG ratings improvement. The team comprises three partners (Olaf Boelsems, Dr. Sonja Harms, Eva-Maria Miermann) and at least one manager (Dr. Manuel Reppmann), placing the firm in the 1-10 employee range.

Business model revenue mechanics are quote-based professional services fees, with no disclosed engagement minimums, recurring SaaS component, or subscription revenue. The firm has no disclosed funding, no parent company, no subsidiaries, and no institutional investors. Strategic positioning leans on the founders' individual professional credentials (Wirtschaftsprüfer, Steuerberater titles, board appointments at US-listed companies) and on academic sustainability research backing the CSRD practice.

Broad incumbents

• Deloitte Germany (Risk & Sustainability Advisory): Big-4 firm's German practice with dedicated sustainability reporting, ESG ratings advisory, ICFR/ICSR, and internal audit services — directly competitive with Green Mine across all three of its service pillars.
• FTI Consulting (Germany): Global advisory firm with a German practice covering ESG, risk advisory, and transaction-related services. Comparable in offering IFRS-aligned reporting, risk management, and ESG advisory for enterprise clients.
• KPMG Germany (ESG & Sustainability Services): Big-4 firm's German practice offering IFRS advisory, CSRD/ESRS reporting, ICFR and ESG assurance. Comparable as the larger incumbent competing directly with Green Mine's service mix for capital-market and mid-market German clients.
• PwC Germany (Sustainability/Climate Services): Big-4 firm's German practice with large-scale CSRD/ESRS, IFRS, and internal controls advisory teams. Overlaps almost entirely with Green Mine's three service pillars at significantly larger scale.
• EY Germany (Climate Change & Sustainability Services): Big-4 firm's German practice offering ESG/sustainability advisory, IFRS reporting, and risk/controls services — comparable in service mix with overlapping target clients in the German Mittelstand and capital-market segment.

Direct peers

• FutureCamp Consulting GmbH: German boutique consultancy headquartered in Munich specializing in sustainability strategy, materiality analysis, and CSRD/ESG reporting implementation — closely comparable to Green Mine's sustainability pillar and similar in size/positioning as a mid-market German advisory.
• ClimatePartner GmbH: German climate action and sustainability consultancy offering CSRD-aligned reporting, GHG accounting, and climate strategy services. Comparable as a German boutique sustainability advisor with overlap in CSRD and Klimaziele/THG-Bilanzierung services.
