Buy & Build Insights – Case Study: Highberg

The market for management consulting is undergoing a fundamental structural change. Clients are increasingly asking for more than isolated strategy consulting; they need partners who are able to accompany end-to-end transformations across disciplines and markets. In this environment, boutique consultancies often lack the scale required for complex, interdisciplinary mandates, while large generalists lack the depth of expertise needed to make a real impact in challenging transformation projects. Highberg was created to fill this gap. This article introduces the portfolio company of AUCTUS, the leading private equity firm for SMEs in Europe.

Strategic Pillars of Success

Highberg is regarded as a reference model for a “multi-specialist” strategy; a strategy that combines the agility and in-depth expertise of boutique consultancies with the operational reach and resources of an international group. Its success is based on five central pillars.

  1. At its core is a commitment to end-to-end transformation. By bringing together eleven leading specialists, Highberg covers the entire value chain from design to implementation – with in-depth expertise in both organizational and digital transformation. This range of capabilities enables the group to successfully support clients in even the most complex and extensive transformation projects.
  2. Equally central is the European platform logic. As an integrated group in key markets such as the Netherlands, Germany and France, Highberg is geared towards implementing cross-border mandates for international clients, exchanging best practices between locations and gaining access to a broad, international talent pool.
  3. In addition, the group taps into significant synergies through collaboration. While the individual teams retain their deep expertise, they benefit from access to a common platform for business development, recruiting and administrative excellence – enabling each specialist to make an impact well beyond their original size.
  4. This model also makes Highberg a magnet for top talent. In a highly competitive market for experienced consultants, the Group offers candidates the dynamic culture of a specialist combined with the career opportunities and infrastructure of an international organization – a combination that few competitors can offer.
  5. Underpinning all of this is an entrepreneurial culture. With a large and operationally active shareholder base, Highberg combines the ownership spirit of boutique consultancies with the strategic advantages of a shared platform – a unique environment that drives both performance and growth.

The Transformation in Numbers

The results of AUCTUS’ buy & build strategy at Highberg speak for themselves. Since the initial investment, the Group has grown from 60 to over 450 employees and has completed nine successful acquisitions. This development not only demonstrates the scalability of the multi-specialist model, but also AUCTUS’ ability to systematically identify and integrate specialist companies and develop them into a coherent platform.

Conclusion and Outlook

The Highberg case shows that a clearly defined platform logic can fundamentally reshape a fragmented consulting market. Instead of unifying the individual firms, Highberg reinforces their individual strengths through a professional commercial and operational backbone. With a continued focus on expansion in the DACH region, the Nordics and Benelux, Highberg is well on its way to becoming a true European champion in transformation consulting and the journey is far from over.
