Meeting Callum in Monza, Italy in 2018 was instrumental in establishing and evolving the shift of content into motorsport. The (then) young British driver was competing for the GP3 title before stepping up to Formula 2 in 2019, where he eventually finished narrowly behind Champion Mick Schumacher in the Covid-affected 2020 season. As a member of the Ferrari Driver’s Academy, Callum took on roles with the Scuderia Ferrari F1 team and Alfa Romeo F1 team in 2021 before moving to the US to become an integral part of the newly established Juncos-Hollinger Racing team in 2022.

Not only was his insight, experience and talent integral in the development of the team through 2022 but grew the young outfit into a strong challenger throughout the 2023 IndyCar season. Over his two years with the team, Callum grew his visibility and popularity within the US market, bringing many brand partnership and original content opportunities.

In 2024, Callum joined the FIA World Endurance Championship grid with Hertz Team JOTA, racing a Porsche 963 Hypercar in the super competitive and growing series. After securing second place in the season opener in Qatar, Callum and teammate Will Stevens took victory at the 6 Hours of Spa-Francorchamps. In addition to his duties in the WEC, Callum has been stepping in at the Arrow McLaren IndyCar team, competing in the opening round of the 2024 Championship and the non-championship event at The Thermal Club. His final outing for Arrow McLaren will be at the 108th Running of the Indy 500 in May 2024.
