Detailed Review
History & Corporate Structure
Greentube was founded as an independent company in 1998 and later acquired by NOVOMATIC, becoming the group's digital division. Under CEO Thomas Graf's leadership since 2011, the company has expanded into regulated markets across Europe, North America, and beyond. In 2025, Greentube acquired the Czech online operator Kingsbet CZ, strengthening its B2C presence, and made strategic investments such as a funding round for Canadian operator PowerPlay in 2026.
Business Model
Greentube generates revenue through B2B platform licensing and game aggregation fees, as well as direct B2C operations via its own casino brands. Its full-service approach provides operators with backend tools, compliance management, and a vast library of content from its own studios and third-party providers.
Products & Platforms
Key B2B offerings include Greentube Plurius, a server-based gaming solution for remote content management; Greentube Pro, a social casino platform; and a game aggregation API with thousands of titles spanning slots, bingo, poker, table games, and iLottery. B2C brands include StarGames (real-money focus in Germany), GameTwist (social casino), and Admiral (retail and online). The company also creates bespoke content for specific markets, such as Dutch classics for the Netherlands.
Markets & Licensing
Greentube holds a remote gambling software licence from the UK Gambling Commission (account 41020) and is authorised by the Malta Gaming Authority (MGA/CRP/120/2006). In the US, it is licensed in New Jersey and Michigan, supplying content to operators like PlayStar (partnership announced February 2026). The company also operates in South Africa through a partnership with World Sports Betting.
Recent Developments
In 2026, Greentube extended its sponsorship of the PDC European Championship via StarGames, renewed South African partnerships, and appointed Michael Bauer as Chief Games Officer, a new role focused on game development strategy. The company continues to expand its North American footprint and invest in emerging regulated markets.
