Thorstensson's first widespread attention began with his creation of the news aggregator GeekBoys.org in 1999. Together with his co-workers, Thorstensson turned his attention to the fledgling medium of electronic sports, which he dedicated GeekBoys' resources as a gaming clan and news syndicate. With the popularity of GeekBoys increasing, Thorstensson, now known by the pseudonym of "bds", achieved several record-breaking feats. According to statistics, he became the single dominant global-recognized Counter-Strike demo player. As one of his most-recognized achievements as a player, Thorstensson created Frag or Die, which remains as the most-popular frag display to date. Additionally, to improve the accessibility of demos, a program call GeekPlay was created, in order to allow immediate initialization of demo play. On September 23, 2001, the German electronic sports organization Schroet Kommando announced the acquisition of his Scandinavian-based team, as a second Counter-Strike squad. With the individuals of Geekboys transitioning to Schroet Kommando, the original GeekBoys website was sold to Swedes David Garpenstahl and Mattias Hjelmstedt. Over the following months, the two communities would slowly merge as the squad operated under the moniker of "SK.Geekboys". During 2001, Thorstensson was also involved with the creation of XSReality.com, which altered its name and changed hands to Englishman Sujoy Roy, eventually becoming ESReality.com. Today, ESReality remains immensely popular as an electronic sports platform.
Schroet Kommando, (which was increasingly referred to as "SK"), began a revolutionizing system in esports, in which users could gain an elite status by partaking in subscription service, referred to as the "SK Insider". On February 1, 2003, Thorstensson introduced the first case of player contractual agreement with the acquisition of Ninjas in Pyjamas to join SK after they had won the 2001 CPL Winter Championship. NiP accepted his offer due to SK's sponsorship deals with companies such as Intel, which allowed them to travel to major competitions worldwide. The resulting team was the highly popular SK.swe team of 2003 through 2004, which became the most dominant team the professional Counter-Strike scene has seen to date. The partnership come to an end on January 2, 2005, when the team opted out of renewing their contracts in hopes of securing a larger share of the prize money and sponsorship with Ninjas in Pyjamas. However, later that year, on June 26, several of the team members returned to SK.
