STS, the biggest Polish bookmaker, has taken its development one step further by taking over BetSys, the software provider that was already its main IT partner. BetSys on the other hand, is a multimillion Euro company, providing services to bookmakers as well as to the Czech Republic's largest lottery operator, Sazka. STSBet has been expanding its services to Europe after dominating the Polish market, operating in the UK, Germany, Gibraltar, Malta, and Latvia among others.
STS's CEO Mateusz Juroszek, said: “We have finalized a takeover of BetSys, in which STS already holds the majority of shares. It is a significant investment which secures our further development. The proprietary bookmaking system, and the possibility for its in-house development, constitute a key advantage in our industry. We have already been generating more than 85% of revenues via online channels, so further growth in IT solutions is of strategic value to us. Only the best European bookmaking companies can boast of their own technology and platform. This is another area that clearly distinguishes us from other operators both in Poland and in Europe.”
BetSys CEO Jiri Najman said that “The integration of BetSys and STS is not only a confirmation of the high quality of our services but above all, it allows us to expand our competence in the sector of IT solutions for the bookmaking industry, which is growing dynamically. BetSys, as part of the STS Group, is guaranteed stable growth and the possibility to create and develop significant competitive advantages for the bookmaker in terms of technology.”
STSBet has been increasing its revenues the past few years, while also actively supporting Polish sports, already being the official sponsor of the Polish national football team and the main sponsor of Jagiellonia Białystok and Lech Poznan, to name a couple.

STS is the most successful bookmaker in Poland, and since 2019 they have been targeting even more regulated European markets, through the launch of STSBet.com and STSBet.co.uk. The sportsbook is provided by BetConstruct, offering the bettors an enhanced betting experience, thanks to features like Counter Offer and Superbet. Additionally, they are an opinionated book publishing their odds earlier than most of the sportsbooks. They bring high odds on football, but unfortunately, this is not the case for basketball and some secondary sports. The addition of live streaming and audio commentary give a huge boost to the live betting section, but on the other hand, they have to offer somehow better odds at this section. STS might not be Bet365 or Bwin, but they still are an excellent mid-class book, deserving your attention.
