We support our portfolio companies and their management in achieving their visions and strategic goals

We invest in successful management teams based on trust, cooperation and speed. Our transactions are characterized by flexible structures and great personal commitment.


  • Entrepreneurial thinking – As management sparring partners, we provide external impulses for strategic options
  • Focus on strategic issues – we do not get involved into day-to-day operations
  • Access to our network – We support with our network, for example, in acquisitions or financing

Flexible Partner for a defined time

  • Tailor made transactions – our fund structure allows us to flexibly address the interests of companies, vendors and management teams
  • Flexible investment horizon – the duration of our engagement can be adjusted individually; longer holding periods possible
  • Personal engagement – We invest private resources and time in each of our companies

We typically take majority holdings in our investments but also take – especially in growth situations – minority positions.

Management Buy-Outs

We support management teams in investing in “their” company as part of corporate transactions and to participate together with us as equal partners in the successful development of the company.


We invest in spin-offs of non-core subsidiaries or business units with the goal of working with existing management to successfully continue the business on a stand-alone basis and generate sustainable growth to increase value.

Succession Solutions

We support family businesses in realizing upcoming changes in their shareholders structures. This includes the continuation of the company with existing or external management or the replacement of individual shareholders.

Growth Capital

We provide growth capital to companies with outstanding technologies or services for example expanding production, developing new products, or internationalization.


We invest in companies with outstanding technological expertise and strategic value creation opportunities.

Technology-oriented companies

Sector focus – capital goods industry, engineering, software and IT services, technological services, medical technology, chemicals

Business concept

  • Successful positioning – Our companies differentiate themselves through technological products or process advantages in growth markets. They have sustainable entry barriers and typically do not operate in cyclical markets.
  • Advanced market life cycle / market leadership potential – Products and services of our portfolio companies provide clear and already established benefits to the customer and therefore a strong market position
  • Company size – We are actively looking for companies with a turnover of more than € 10 million (smaller with high growth and / or outstanding technology)

Qualified Management

Our investments are always lead by excellent managers who value strategic support. Innovation paired with implementation strength and management experience are the most important prerequisites for success.

Focus on German speaking Europe

We primarily focus on Germany, Austria and Switzerland, but can also invest outside our core regions.

Majority and minority participations

We prefer to invest as majority shareholders but can also take minority positions – especially in growth situations

Transaction size

We typically invest in transactions valued up to € 50 million with our equity investment sweet spot ranging from € 3 – € 15 million. In larger transactions we invest together with partners.
