Boxxer

Founded by Ben Shalom, Boxxer began as Ultimate Boxxer, organising eight-man professional boxing elimination tournaments starting in April 2018 and preceding to host a total of six tournaments under the original name. In August 2020, Ultimate Boxxer rebranded to Boxxer, and announced its first signee; the winner of the Ultimate Boxxer 3 tournament, Derrick Osaze. The following month, and under the new branding, Boxxer announced its seventh tournament, "Boxxer Series 7", would take place in November 2020 with a new four-man elimination format.

In June 2021, it was announced that Boxxer had signed a four-year deal with Sky Sports. In September, Boxxer revealed their roster of fighters, including Hughie Fury, Savannah Marshall and Caroline Dubois, as well as co-promotional deals with Claressa Shields and Chris Eubank Jr. A co-promotional deal was also made with Bob Arum's Top Rank in regards to the world title fight between Josh Taylor and Jack Catterall. Boxxer's first event on Sky Sports was a co-promotion with Wasserman Boxing, featuring Eubank Jr. on 2 October 2021.

The most notable, high profile event associated with Boxxer was between domestic rivals Amir Khan and Kell Brook on 19 February 2022.

On 8 August 2025 it was announced that Boxxer had signed a deal with BBC Sport.

On 9 June 2026, it was announced that Boxxer had secured a new multi‑fight broadcast deal with DAZN. The deal allowed Boxxer to stage larger, globally distributed fight cards, and potentially deliver pay‑per‑view events later in 2026. It was also noted that the BBC deal would continue, meaning the company would operate across both free‑to‑air and global streaming platforms. The first event under the deal was scheduled to be a rematch between Callum Simpson and Troy Williamson on 8 August 2026.

Under the name Ultimate Boxxer, the tournament originally featured eight fighters from a given weight competing in 3 x 3 minute rounds in one night, with the winner of the inaugural tournament being awarded £16,000 and a golden robe.
