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.

On 1 February 2003 Thorstensson introduced the first case of player contractual agreement with the acquisition of Ninjas in Pyjamas to join SK after they had won an early Cyberathlete Professional League Counter-Strike tournament.

NiP accepted his offer due to SK's sponsorship deals with companies such as Intel, which allowed them to travel to major competitions worldwide.

[14] This seemed to come to an end on 2 January 2005, when the team opted out of renewing their contracts in hopes of securing a larger share of the prize money and sponsorships with Ninjas in Pyjamas.

On 9 December 2009 Thorstensson announced his retirement from SK Gaming to further pursue his web development profession, maintaining Geekboys.org as his personal business website.

[19] Alongside Sofie Lundström, Thorstensson founded a marketplace lending platform service intended to connect consumers with small businesses in need of loans called Toborrow in 2013.

[4] Over the successive three years of Thorstensson's tenure, EQT would maintain a €566 million fund and develop Motherbrain, a tool for identifying promising startup ventures.

[22] After a $9 million Series A funding round, the esports technology and services company Popdog was launched in December 2018, with Thorstensson as a co-founder, CTO and CPO - marking his return to the scene, after nine years.

Joining in launching Popdog were former Evil Geniuses (EG) owner Alex Garfield as CEO, consultant Niles Heron as CSO and former EG COO Colin DeShong as CCO.

[5] The first brands acquired with Popdog's launch included the premier gaming talent agency Loaded, the world's largest analysis tool for Twitch called Noscope, as well as the Catalyst Sports & Media's e-sports section.
