We develop a personal strategy
A good M&A transaction depends on investors, who want to buy a company or invest in a project.
Over the years, we have built up a network of wealthy entrepreneurial families, family offices and other strategists who are interested in sustainable and responsible corporate development.
Die Qualität unseres Netzwerks ist unser Kapital
Eine erfolgreiche M&A-Transaktion hängt von Investoren ab, die ein Unternehmen kaufen oder in ein Projekt investieren wollen.
Über die Jahre haben wir ein Netzwerk aus vermögenden Unternehmerfamilien, Family Offices und anderen Strategen aufgebaut, die an einer nachhaltigen und verantwortungsvollen Unternehmensentwicklung interessiert sind.
We support entrepreneurial families
who employ between 20 and 200 people. In some cases, we have been working with them for years. This is only possible with trust, sensitivity and discretion.

Unser Leitbild: Starke Werte in Zeiten des Wandels
Wir wissen, dass es beim Verkauf oder der Übernahme eines Unternehmens nicht nur um Zahlen geht. Es geht auch um Erinnerungen, Gewohnheiten – und oft auch um die Sorge um die Zukunft des Unternehmens. Für viele Unternehmer sind Mitarbeiter, Lieferanten und Kunden Teil der Familie geworden. Gerade Mitarbeiter machen sich oft Sorgen um die Zukunft. Wir kennen diese emotionalen Herausforderungen und unsere langjährige Erfahrung ermöglicht es uns, für alle Beteiligten passende Lösungen zu finden. Verantwortung und Vertrauen stehen bei uns an erster Stelle.Continuity in climate protection since 2021: CO₂ compensation through renaturation of the Grotmoor
We are firmly committed to reducing our ecological footprint and are continuing our efforts to ensure a sustainable future. We are therefore building on our previous efforts and continuing to provide targeted support for the renaturation of a valuable German moorland landscape this year.
Moorland renaturation remains our first choice for completely offsetting unavoidable CO₂ emissions. Moorlands are invaluable allies in the fight against climate change, as they store many times more carbon than forests in a small area. By restoring and protecting these unique ecosystems, we are actively helping to stop CO₂ emissions and promote biodiversity.
This year, we are supporting the rewetting of the Grotmoor in the Segeberg district (Schleswig-Holstein) through the “MoorFutures” program. Our contribution will enable the offsetting of 25 tons of CO₂ and ensure the protection of this important habitat for the next 50 years. In this way, we are once again making a small but effective contribution to regional climate and nature conservation.
Opportunities for disadvantaged children: We are once again supporting the Förderturm
Following last year’s Family Day, we have once again sponsored ‘Förderturm – Ideen für Essener Kinder e.V.’ in 2026. The event took place at the ‘Rutherhof Glücklich’ in Essen-Schuir and, in summery weather, brought together numerous families, supporters and partners.
Förderturm supports children and young people from socially disadvantaged backgrounds with educational and leisure activities and is funded entirely through donations. Events such as Family Day make an important contribution to this.
We are delighted to be working together again and would like to thank the organising team and everyone involved for a day that brought real joy to the children and their families.
