50: Webis (2016)
The majority of revenue for the AIM-listed Webis comes from its WatchandWager brand, which offers advance deposit wagering (ADW) on horseracing to customers around the world.
In the 2015 financial year, WatchandWager saw ADW turnover grow 57% to £48m, with the uptick driven by high-roller wagering in Hong Kong.
More recently, the operator reported “significant increases” in turnover and active player numbers through its US website and mobile platforms.
