What We Do
Every day millions of sports fans enjoy using Sofascore, one of the best sports platforms in the world.
Sofascore has everything a sports fan needs – the fastest live score and super-detailed statistics for 25 sports.
However, our relentless enthusiasm for sports and technology has spilled into things much more sophisticated. It is our unique products such as Sofascore Ratings, Heatmaps, Shotmaps, Attack Momentum and Attribute Overview that set us apart from the rest – and are the key factor that helped us reach 28 million monthly active users. Created by our constant drive to translate raw data into appealing and intuitive insights, these products represent graphical summaries of key football statistics. They are our answer to the needs of a modern, informed sports fan who wants much more than scores – but wants it fast.
We believe that what got us here will take us much further too; acting on our endless drive for sports and technology and reacting on every single piece of users’ feedback. Because, although we created Sofascore, we are but a tiny fragment of the huge Sofascore community. With that in mind – we push on!
