Succession with growth: How Buy & Build enables family businesses to have a second career

Managing company succession is one of the most emotional and complex tasks in the German SME sector. If one’s own children take a different path or there is a lack of qualified managers in the company, there is often a threat of the end of a life’s work that has been built up over generations.

Traditionally, owners are then faced with the choice of selling the company to a competitor (often associated with the loss of identity and jobs) or the classic sale to a financial investor who primarily focuses on cost savings. However, there is a third option that sees succession not as a retreat, but as the starting signal for a second career for the company: the buy & build strategy. AUCTUS is a pioneer in the German-speaking buy & build segment and has accompanied numerous companies on their way to market leadership over the last 25 years. This article looks at the opportunities of a buy & build concept for medium-sized companies.

The principle: from local champion to market leader

In a buy & build strategy, an experienced investor (such as a private equity company) acquires a stable medium-sized company as a so-called platform company. This company forms the solid foundation.

In the next step, further organic growth of the platform company is targeted. In addition, (smaller) companies from the same or a complementary sector will be acquired (so-called add-ons). The formerly owner-managed family business will thus become the core and driving force behind a new, rapidly growing group of companies.

Why Buy & Build is the ideal succession solution

For family entrepreneurs, this approach offers unique strategic and personal advantages:
  • Preserving the identity: The platform company remains the core. The name, culture and values of the founder are not rationalized away, but used as a basis for further growth.
  • Central “operational backbone”: tasks such as IT, controlling, HR and purchasing are professionalized at Group level. This relieves the burden on operations and creates space for real growth.
  • Financial security & upside potential: The entrepreneur liquidates a large part of his assets on the initial sale. However, he often retains a minority stake and benefits massively from the increase in value of the entire group on the subsequent overall exit. The family’s assets are no longer largely tied up in the company, but are “behind the firewall”.

Practical example: When a craft business becomes a champion

The example of the Builtech Group shows how successful this transformation can be in reality together with the buy & build expert AUCTUS. This was based on a single, regionally anchored trade company in the field of technical building equipment (TGA).
Thanks to a consistent buy & build strategy, over 50 individual companies were brought together under this umbrella. The result: Group profits multiplied dramatically during the holding period, jobs were secured and a modern, European market leader with an annual output of over 500 million euros was created.

Conclusion: The second career for your life’s work

Buy & Build breaks down the old prejudice that succession must mean the “end” of a company. For healthy family businesses with a strong core, it is the exact opposite: the start of a completely new growth league. The entrepreneur’s life’s work is not only preserved, but serves as the foundation for a genuine success story.
