Complexity Shuts Down After 23 Years as Jason Lake Leaves Legendary Esports Brand

One of North America’s longest-running esports organizations has ceased operations after 23 years, with founder Jason Lake confirming his departure and the Complexity intellectual property returning to former owner GameSquare.

Complexity has officially ceased operations, bringing an end to a 23-year run under the leadership of founder Jason Lake and closing a major chapter in North American esports history.

Lake confirmed the shutdown on September 23, explaining that the decision to wind down the organization had actually been made at the end of 2025. He said Complexity had reviewed the state of the business and its ability to raise sufficient capital before concluding that an orderly closure was the most responsible course of action.

Financial pressure surrounding Complexity’s 2024 reacquisition played a significant role. Lake and an investor group operating as Global Esports Properties bought the organization back from GameSquare for $10.36 million. According to GameSquare’s official announcement, only $750,000 was due at closing, while approximately $9.61 million was financed through a three-year seller note carrying 3% annual interest.

Lake said the organization assessed its prospects of raising enough capital to meet obligations connected to that seller-held note before choosing to close. As a result, the Complexity intellectual property has now reverted to GameSquare. This means the organization has stopped operating under Lake and his core team, although the Complexity name itself continues to exist as an asset owned by GameSquare.

The closure had been preceded by a gradual reduction in Complexity’s competitive activities. In August 2025, the organization withdrew from Counter-Strike after Lake acknowledged that worsening esports economics and declining revenue had made it impossible to properly support a tier-one roster. At the time, he said Complexity had explored investment and additional revenue opportunities but had been unable to find a sustainable solution.

Counter-Strike was particularly important to the organization’s identity. Complexity first entered the game in 2004 and maintained a roster for all but one of the following 22 years. Its history included victories at ESWC 2005, CPL Summer 2006 and ESL Challenger Jönköping 2024, as well as appearances at ten official Counter-Strike Majors. The organization also competed across numerous other esports titles during its long history.

After leaving Counter-Strike, Complexity continued operating on a smaller scale, including involvement in the NA Revival Series and a Halo Infinite roster during the latter part of 2025. The final shutdown nevertheless means that Lake and members of his long-standing core staff are no longer connected to the organization for the first time since its creation.

For Lake, however, the announcement does not represent retirement. After taking a sabbatical during 2026 to spend more time with his family, he said he is interested in building something new and would like to remain involved in esports if the right opportunity emerges.

Complexity’s closure is therefore both the end of one of North American esports’ most recognizable organizational runs and another example of the financial pressures facing established teams. The return of the IP to GameSquare leaves open the theoretical possibility that the Complexity brand could appear again in the future, but for now the organization built and led by Jason Lake has reached the end of its 23-year journey.
