OG

OG is a professional esports organisation established in 2015 in Europe. It emerged from a Dota 2 squad originally known as (monkey) Business, formed by former Team Secret players Johan “N0tail” Sundstein and Tal “Fly” Aizik together with David “MoonMeander” Tan, Fritz “Frtz” DG and Andreas “Cr1t-” Nielsen. After adopting the OG name, the team rapidly became one of the most successful organisations in competitive Dota 2, winning the Frankfurt Major in 2015, the Manila Major in 2016, the Boston Major in 2016 and the Kiev Major in 2017. The organisation’s defining achievement came at The International 2018. Following major roster departures and an unsuccessful route through the normal qualification system, OG rebuilt around Topias “Topson” Taavitsainen, returning player Anathan “ana” Pham and former coach Sébastien “Ceb” Debs, alongside N0tail and JerAx. The reformed lineup qualified through the European open qualifiers and won the tournament after a close grand final against PSG.LGD. OG repeated the feat at The International 2019, defeating Team Liquid and becoming the first organisation to win The International twice and the first to win it in consecutive years. OG has expanded beyond Dota 2. It entered Super Smash Bros. in 2018, Counter-Strike in 2019, Valorant in 2021 and Rocket League in 2024. Its Counter-Strike operation transitioned from Counter-Strike: Global Offensive to Counter-Strike 2 and underwent several roster rebuilds. The Valorant division also partnered with LDN UTD for the 2022 EMEA competition cycle, but the combined roster was later disbanded after failing to secure a place in the partnered league. The Dota 2 division has continued to experience cycles of rebuilding and veteran involvement. A new generation led by players including Yuragi, bzm, ATF, Taiga and Misha won the ESL One Stockholm Major in 2022, giving OG its fifth Dota 2 Major title. The organisation also won ESL One Malaysia later that year. In 2024, OG participated in the 1win Series Dota 2 Fall tournament and was included in the Esports World Cup Foundation Club Support Program. In 2025, OG relocated its competitive region from Europe to Southeast Asia after acquiring the roster of Team Aureus, creating an all-Filipino Southeast Asian lineup for its participation in PGL Wallachia Season 6. The same year, Chiliz Group announced the acquisition of a majority stake, adding a new ownership and fan-engagement dimension through the Socios.com ecosystem.

OG began in August 2015 as (monkey) Business, a Dota 2 team formed by Johan “N0tail” Sundstein and Tal “Fly” Aizik with MoonMeander, Frtz and Cr1t-. The roster had previously been associated with Team Secret players and quickly established itself in the European competitive circuit. After a strong run through the European qualifiers for the Frankfurt Major, the team adopted the OG name and won the tournament in November 2015. The organisation’s early period was marked by rapid competitive success and frequent roster adjustments. OG underperformed at the Shanghai Major in March 2016 but recovered by winning the Manila Major in June. That victory made OG the first team to win two Valve-sponsored Dota 2 Majors. After an unexpectedly early elimination at The International 2016, MoonMeander, Miracle- and Cr1t- departed. Their replacements—s4, ana and JerAx—helped OG win the Boston Major in December 2016 and the Kiev Major in 2017. The Kiev event also brought the organisation wider documentary exposure through Valve’s True Sight series. The most consequential restructuring occurred in 2018. Fly and s4 left for Evil Geniuses, while other roster changes left OG without direct or regional qualification eligibility for The International. OG added Topson, brought Ceb up from his coaching role and welcomed ana back from a competitive break. The new lineup qualified through the European open qualifiers and then won The International 2018, defeating PSG.LGD in a five-game final. The victory was widely viewed as an underdog achievement because OG had entered through the open path and had rebuilt shortly before the event. OG maintained its core and returned to The International 2019 with a direct invitation after a strong Dota Pro Circuit season. It dominated the group stage and upper bracket before beating Team Liquid in the final. The result made OG the first two-time International champion and the first to win the event in consecutive years. During this period, ana took breaks from competition, the organisation played an exhibition series against OpenAI Five, and coaching responsibilities changed. From 2020 onward, OG underwent repeated cycles of retirement, leave and roster renewal. JerAx retired, Ceb moved away from the active lineup, and Sumail, MidOne and Saksa joined during the 2020 restructuring. Ana later returned briefly before retiring, while Sumail rejoined. OG qualified for The International 2021 through regional competition but was eliminated by eventual champion Team Spirit. At the end of 2021, several members of the championship-era roster stepped away, and OG introduced a younger lineup built around Yuragi, bzm, ATF, Taiga and Misha. That younger team won the ESL One Stockholm Major in 2022, with Ceb and N0tail serving as stand-ins during the tournament, and later won ESL One Malaysia. OG also broadened its portfolio. It entered Super Smash Bros. in 2018, formed a Counter-Strike division in 2019, created a Valorant division in 2021 and partnered with LDN UTD for the 2022 EMEA Valorant cycle. The Valorant project ended after the combined roster failed to reach the partnered league. Counter-Strike rosters were rebuilt several times and continued into Counter-Strike 2. In 2024 OG added Rocket League and remained active in Dota 2 events, including the 1win Series Dota 2 Fall tournament. Its business model also increasingly intersected with sponsorship and fan-engagement programs. OG was part of the Esports World Cup Foundation Club Support Program in 2024, while the program drew criticism from observers who characterized it as a Saudi sportswashing vehicle. In September 2025, Chiliz Group announced a 51% majority acquisition. Later in 2025, OG shifted its competitive region to Southeast Asia after acquiring Team Aureus’s roster, marking a new phase focused on an all-Filipino lineup and Southeast Asian representation.
