In 2018, Ospreay announced that he would be starting his own promotion, Frontline Wrestling. He said that Frontline would be a British Puroresu style company and that wants to take wrestling in England back to being seen as a sport. On 28 June 2018 they ran their first event, "Build Me An Empire". Upon the one year anniversary of the promotion, Will would sell Frontline to move to Japan and pursue a full time schedule in New Japan Pro Wrestling.
