Overview
What they do
Founded in 2001 following the €1.5 billion sale of Helios Kliniken to Fresenius, ATON GmbH serves as the generation-spanning investment vehicle for the Helmig family. The firm operates as an industrial holding company rather than a traditional venture capital fund, focusing on acquiring majority stakes in established, market-leading B2B companies. It is highly regarded in the DACH ecosystem for its "family capital" approach, which provides portfolio companies with financial independence, conservative leverage, and strategic support without the exit pressure of typical private equity fund lifecycles. Today, the ATON Group's portfolio companies employ over 15,000 people globally and generate over €2.2 billion in annual operating performance.

What they look for
ATON GmbH provides "Familienkapital für Wachstum und Innovation" (Family capital for growth and innovation). The firm invests in innovative companies that demonstrate market leadership in their core B2B business areas, prioritizing sustainable and profitable growth over short-term gains. They look for established business models with measurable success metrics (earnings, cash flow), a strong focus on B2B markets, and the ability to act independently of financial market fluctuations. They strongly prefer majority shareholdings to ensure close, trust-based cooperation and direct strategic influence.
