Septeo acquires legal technology software company STP One

The Karlsruhe-based legal tech company STP One, which offers AI-driven contract analysis, is getting new owners. Financial investor BU Bregal Unternehmerkapital (which emerged from the family office of the Dutch billionaire Brenninkmeyer family), and Maguar Capital Management, are selling 100% of their shares in STP One to French software company Septeo. According to finance industry sources, the deal values the company at 560 million euros.

Merger with Septeo

The merger of STP One and Montpellier based Septeo, part of the portfolio of the private equity firm Hg Capital which manages more than 100 billion dollars, is intended to create a European legal tech platform.

Bregal, which manages a total of 7 billion euros, acquired STP One in 2020, together with software-focused private equity firm Maguar Capital. They recruited Oliver Bendig as the new CEO and Dirk Eisenberg as the new CTO. Since then, the company has been expanded from a national specialist in insolvency software to a multi-vertical Software as a Service (SaaS) platform, and completed a number of strategic acquisitions. STP One operates in Germany, Benelux and Eastern Europe. The company employs more than 400 people at twelve locations, and serves more than 8,000 customers, including law firms, insolvency administrators and legal departments.

The merger partner Septeo employs over 2,400 people, generates annual revenue of around 460 million euros and, according to its own information, is one of the top 10 software companies in France. The company offers solutions for notaries, solicitors and tax advisors.

Providing the legal industry with cloud and AI solutions

Bregal partner Philipp Struth said the merger is an example of how the financial investor is developing „medium-sized software companies into European market leaders“. According to Hugues Galambrun, CEO and founder of Septeo, both companies share „the same vision: to drive the digital transformation of the legal industry with modern cloud and AI solutions“.

The transaction is expected to close in the first quarter of 2026, subject to regulatory approvals. Raymond James was M&A advisor to Bregal.
