What sets us apart
- Personal support
Mathias Westerbarkei looks after you personally, from the initial consultation to receipt of the purchase price. No delegation to junior advisers. We only bring in further project members if you expressly ask us to.
- Independent and confidential
We are owner-managed and independent. No large organisation to keep busy, and no conflicts of interest. We work closely with your existing advisers (tax advisers, auditors, lawyers).
We never disclose your company’s name without your consent. Every potential buyer signs a confidentiality agreement in advance.
- Smaller companies too
Many M&A advisers only take on larger mandates. We support transactions from around €1 million to €100 million enterprise value, all to the same standard. Smaller mandates are expressly welcome.
- Industry and M&A experience
Mathias Westerbarkei spent 18 years at CLAAS KGaA mbH, from controlling through the Renault Agriculture integration to Head of Mergers & Acquisitions. There he led earnings improvement programmes worth around €100 million, several of them with consulting teams from McKinsey, BCG and Roland Berger. He then became CFO of DTS IT AG. Since 2017 he has supported owner-managed companies. From 2023 to 2025 he was also Investment Manager in the family office of the Goldbeck Group.
- Our own self-learning AI system
We work with an AI system that we have built over a long period for exactly these tasks. It comprises around 1,260 review questions for due diligence (the buyer’s detailed review of a company) and over 100 proven workflows. Every figure it produces is backed by evidence.
The system speeds up valuation, the search for buyers and the preparation of documents. It is the core of our AI Value Creation programme. If you wish, your data stays entirely with you.
- Network
We are a member of the Bundesverband Mergers & Acquisitions gem. e.V., the German M&A association, and have access to a continuously maintained network of strategic buyers, private equity firms and family offices. For international projects and the AI-supported search for suitable companies, we work with our partners.
Fees
For selling and buying a business, our fee combines a monthly retainer with a success fee that only becomes due on completion of the transaction. This way we share the risk with you.
AI Value Creation has its own structure: a fixed price for the initial assessment, then, during implementation, a monthly retainer plus a share in the demonstrated increase in value.
You will receive a specific proposal in the initial consultation, which is free of charge and without obligation.
