Microsoft's Windows brand has signed twin brothers Kade and Tye Ruotolo, the ONE Championship submission grappling world champions, to a sponsorship deal, weeks before Tye challenges Christian Lee for the ONE lightweight MMA world title.

Windows introduced the 23-year-old Americans in an Instagram post on 2 October. "Their obsession doesn't stop when the fight does. Meet the Ruotolo brothers," the post said. "Watch their story at the link in bio." The financial terms have not been made public.

Tye, the ONE welterweight submission grappling champion, faces Lee at The Inner Circle 37 at Lumpinee Stadium in Bangkok on Friday 6 November. ONE has scheduled the event for 18:30 in Bangkok, which is 11:30 in the UK and Ireland, and it streams for members on live.onefc.com. Lee, 28, holds ONE's lightweight and welterweight MMA titles and has an 18-4 record, with 17 wins by finish. Ruotolo is 2-0 in MMA. He submitted Lee's younger brother Adrian with a second-round rear-naked choke on his debut, handing him the first defeat of his career, then stopped Shozo Isojima inside three minutes.

Kade, the ONE lightweight submission grappling champion, is 4-0 in MMA with four finishes. He returned from a torn ACL in May to knock out former Pancrase champion Hiroyuki Tetsuka at 2:02 of the second round at Lumpinee Stadium, but an injury he picked up afterwards forced him out of a planned grappling title defence against Fabricio Andrey.

The brothers, born in Maui and raised in Huntington Beach, California, have competed since the age of three. Kade became the youngest ADCC world champion at 19 when he won the 77kg division in 2022, and won the $1m grand prize at the first Craig Jones Invitational in 2024. Tye won the inaugural ONE welterweight submission grappling title in November 2023.
