Company profile

researched Aug 2026

Slamball LLC organizes and operates sports and entertainment events built around SlamBall leagues and competitions. The sport is a mashup of basketball, football and trampolines. The company handles sports branding, fan engagement, and the broadcast of live events and highlights, serving fans of alternative, action-oriented sports across the United States and North America.

The league originally aired on The National Network (later Spike TV) in the early 2000s, generating short-lived attention before being shut down in the U.S. as ratings declined during its second season. Following an $11 million Series A round announced in March 2023, the company planned a relaunch as a six-week competition plus a seventh playoff week beginning in July 2023, played in Las Vegas. Games run roughly 20 minutes, with three games staged per night.

Founding story

Founder and CEO Mason Gordon and Mike Tollin, a producer associated with the Chicago Bulls docuseries "The Last Dance" who was involved in launching the league the first time, spent about nine months assembling the investor group behind the relaunch. Tollin said the group waited until market conditions for alternative sports were favorable and the desired investor roster was in place.

Business model

The company monetizes a live sports property by staging SlamBall competitions as events and distributing games and highlights through broadcast, streaming and social media channels, supported by sports branding and fan engagement activity.

Traction

Closed an $11 million Series A in March 2023 with backing from sports and consumer investors, and scheduled a seven-week relaunch season in Las Vegas for July 2023.

Latest developments

In March 2023, the company disclosed an $11 million Series A led by Roger Ehrenberg's IA Sports Ventures and Eberg Capital, with participation from David Blitzer, Michael Rubin, Gary Vaynerchuk, David Adelman and Blake Griffin, alongside plans for a July 2023 relaunch in Las Vegas and ongoing distribution negotiations.

Full profile — market position, go-to-market, geography, history, risks & controversies

Market position

The company positions SlamBall as an alternative-sports property, with its founders comparing its relationship to the NBA as analogous to the UFC's relationship to boxing. Its relaunch coincided with streaming platforms including ESPN+, Paramount+, Peacock and Prime Video expanding their acquisition of sports rights, including alternative sports.

Go-to-market

The relaunch was structured as a Las Vegas-based series of six competition weeks plus a playoff week, with games of about 20 minutes played three per night. Management said it intended to distribute games simultaneously via a traditional TV network, a streaming service and a social media platform, and reported advanced talks with broadcast and streaming distributors without naming partners.

Sports fans seeking alternative, action-oriented entertainment in the United States and North America, plus television, streaming and social media platforms acquiring live sports content.

Geography

Headquartered in Studio City, California, with events planned in Las Vegas and audience reach described as the United States and North America.

History

SlamBall gained attention in the early 2000s, airing on The National Network, which later became Spike TV, before being shut down in the U.S. when ratings fell in its second season. More than 20 years later, the company raised an $11 million Series A round announced in March 2023 and prepared to relaunch the league in July of that year in Las Vegas.

Risks & controversies

The league's earlier U.S. run was shut down after ratings declined in its second season. At the time of the funding announcement, distribution agreements for the relaunch had not been finalized.
