Atlantic Grupa has invested €11 million in hydration brand Waterdrop, acquiring a minority stake and securing a seat on the company’s investment committee, deepening an existing distribution partnership across Austria, Croatia, Serbia and Slovenia.

The move strengthens a collaboration that began as a regional distribution agreement and now shifts into a closer strategic and financial relationship. Through the new stake, Atlantic Grupa will gain direct insight into Waterdrop’s operations and support its long-term growth strategy.

Founded in Vienna, Waterdrop develops 'Microdrinks,' compressed sugar-free cubes designed to flavour water with fruit and plant extracts. The company positions the products as a healthier and more sustainable alternative to traditional soft drinks. Production is handled in its own facility in Germany, which it says helps maintain quality control and consistency.

Over the past decade, Waterdrop has expanded into a global brand with around €150 million in annual revenue. It now operates across Europe, the United States, Australia and Japan, combining direct-to-consumer sales with branded retail stores and selected distribution partners.

The company runs roughly 50 physical stores in major cities, blending digital and in-store retail experiences.

Its growth has also been supported by high-profile marketing partnerships, including collaborations with international sporting events such as the Australian Open and professional tennis players.

Martin Donald Murray, chief executive of Waterdrop, said the investment builds on a strong existing relationship with Atlantic Grupa and adds further strategic depth to their cooperation.

Lada Tedeschi Fiorio, group vice president for corporate strategy and investments at Atlantic Grupa, said the company sees strong potential in Waterdrop’s international expansion and is confident in its long-term growth prospects, particularly in European markets.
