Our shareholders and the investors in DBAG funds have entrusted us with capital. They expect us to invest these resources in attractive and promising investments. It is therefore crucial for us to maintain a high-quality and sufficiently robust pipeline of potential investment opportunities at all times. This requires a broad range of market activities: from several hundred projects each year, our objective is to successfully complete three to six transactions annually.
Initiating and managing this deal-sourcing process is one of the core responsibilities of Business Development. The team proactively identifies companies of interest to DBAG, with a particular focus on succession situations. At the same time, we also pursue transactions with financial investors and corporate sellers.
In addition, Business Development coordinates our collaboration with investment banks and M&A advisors, which are also an important source of new transactions. Accordingly, maintaining relationships with intermediaries—as well as with market participants and competitors—is a key component of our work.
Another critical success factor in deal sourcing is the expansion and maintenance of our network of industry experts—the so-called Executive Circle. This group primarily consists of former board members and CEOs from the sectors in which DBAG invests. They support our team with their experience, expertise, and networks. To preserve the unique value of this select circle of business leaders, it must continuously evolve—actively shaping this development is also part of our responsibilities.
Furthermore, the Business Development team represents Deutsche Beteiligungs AG at conferences and trade fairs. At these events, we provide insights into our many years of experience in the private equity environment and explain DBAG’s investment strategy. In this way, we sustainably strengthen DBAG’s market outreach and presence.
To us, an industrial expert is someone who, thanks to his or her in-depth knowledge of the industry, backs us in preparing investment decisions and supporting portfolio companies. Industrial experts advise the investment team as it analyses potential investments and they provide support as a strategy is developed for each of the companies. In addition, seats on supervisory boards or advisory councils are often filled by industrial experts.
If you have a proven track record successfully managing a large internationally operating company in one of our relevant sectors and if working entrepreneurially remains appealing to you, then feel free to contact me.
