After being coached by Thomas Jones, Jay White made his debut in 2013 in some federations of the English independent circuit. In early 2014 he was able to support Prince Devitt in a tag team match and exchange his phone number with him at the end of the match.
At the beginning of 2015, Jay White was contacted by Bad Luck Fale, Prince Devitt's partner in the Bullet Club, who offered him a place in the development sector of New Japan Pro-Wrestling; after a few months White meets Fale again, who convinces him to move to Japan. White debuted in New Japan Pro-Wrestling in the month of February collecting, as usual for newcomers, a long losing streak.
On July 17, 2021, at Slammiversary, Jay White made his first Impact Wrestling appearance, attacking David Finlay after a match with Kenny Omega and the Good Brothers.
On February 19, 2022, at No Surrender, he defeated Eric Young; the same evening he attacked his Bullet Club teammates Tama Tonga and Tanga Loa to help The Good Brothers retain the Impact World Tag Team Championship and celebrated with them with the Too Sweet gesture.
On the February 9, 2022 episode of Dynamite, Jay White made his first appearance for All Elite Wrestling, helping Adam Cole and the Young Bucks attack Rocky Romero and Trent Beretta backstage; two days later at Rampage, he attacked Beretta again after the latter, along with Rocky Romero, lost a tag team match against the Young Bucks.
