What UnternehmensBörse Grönig & Kollegen AG does

UnternehmensBörse Grönig & Kollegen AG is a German M&A advisory firm headquartered in Kelkheim-Fischbach near Frankfurt am Main, founded in 2010 by Reiner Grönig. The firm specializes in company sales, business acquisitions, and succession planning for medium-sized, owner-managed German companies with annual revenues between €1.0 million and €50.0 million. Its core offering combines personalized, relationship-based advisory services — including valuation, due diligence, optimization consulting, and coordination with specialized tax advisors and lawyers — with a digital marketplace platform ('Marktplatz') that lists quality-tested sales offers, purchase requests, and equity participation opportunities with anonymized company profiles and detailed sales memoranda. The firm operates with a staff of approximately 15 people, led by Reiner Grönig (Founder/Vorstand) and Alexander Grönig (Vorstand), with Thomas Kober de Almeida as Chairman of the Supervisory Board.

The company's revenue model is exclusively success-based: fees accrue only upon the closing of a sale or purchase transaction executed through the UnternehmensBörse. No upfront fees are charged, and clients receive a complimentary initial consultation and purchase price indication. Go-to-market is sales-led and direct, supplemented by referral channels through institutional partnerships with Offensive Mittelstand, Unternehmensnachfolge, and the Bundesverband mittelständische Wirtschaft. Coverage is nationwide across Germany, with incremental reach into Austria and Switzerland within the DACH region. The firm has been recognized by DIE DEUTSCHE WIRTSCHAFT with the DDW Excellence Seal as 'Exzellenzberater des Deutschen Mittelstands'.

Disclosed transaction activity includes recurring multi-year deal flow across diverse sub-sectors such as online trading, metalworking, fire protection, IT, language schools, measurement technology, engineering, facility management, and real estate brokerage. Strategic emphasis is on continuity of client representation through a dual-consultant team structure, discretion in transaction handling, and full-process support from contract initiation through closing.

Direct peers

• Clairfield International: International mid-market M&A advisory firm with a strong Germany/DACH presence. Comparable in target customer (owner-managed mid-market companies), service mix (sell-side, buy-side, succession), and cross-border deal execution capability.
• ConAlliance GmbH: German M&A and succession advisory firm focused on the Mittelstand. Very close peer: similar geographic focus (Germany/DACH), similar owner-managed Mittelstand target segment, and similar full-process advisory model.
• M&A Worldwide: Global alliance of independent M&A advisory firms serving lower-mid-market companies. Comparable target segment (often €5–100M enterprise value), similar succession and sell-side focus, and similar marketplace-style referral network structure.
• IMAP M&A Worldwide: Global mid-market M&A advisory network with active coverage of Germany Mittelstand transactions. Directly comparable: serves similar owner-managed companies in the lower-to-mid market with cross-border buyer/seller reach, just at a larger network scale.

Broad incumbents

• Ebner Stolz M&A: Top-10 German mid-market advisory firm offering M&A, succession, valuation, and tax/legal support under one roof. A broader incumbent that overlaps heavily on Mittelstand succession and valuation but operates at significantly larger scale across multiple service lines.
• Rödl & Partner M&A: International mid-market advisory firm with strong Germany presence covering M&A, succession, and integrated legal/tax support. Comparable in offering breadth and Mittelstand focus, but operates at much larger scale as part of a global professional services firm.
• BDO Germany M&A Advisory: Large German audit and advisory network with active mid-market M&A practice. Comparable target segment and succession focus, but operates as part of a full-service audit/tax consulting platform rather than a pure-play M&A marketplace.

Regional players

• VR M&A Partners / DZ Bank Group: M&A advisory arm of the German cooperative banking sector (Volksbanken/Raiffeisenbanken), focusing on Mittelstand succession transactions. Comparable target customer and deal-size band, with regional banking-network origination rather than an open marketplace.

Emerging players

• Acquireo / Acqwire: Digital M&A marketplace targeting lower-mid-market company transactions. Comparable in being an online marketplace for SME buy/sell, but operates as a pure software platform without the in-house succession advisory and success-based deal support that defines the subject firm.
• Deutsche Beteiligungs AG: Frankfurt-listed German mid-market private equity and M&A advisor. Adjacent comparator in Mittelstand deal flow and succession-oriented investments, but operates from the principal-investor side rather than pure advisory, and serves larger deal sizes.
