Theo’s recent run of songwriting success reached a new high with 16 co-writing credits on Louis Tomlinson’s third studio album, How Did I Get Here?, which debuted at No. 1 on the UK Official Charts at the start of 2026. With an ever-growing list of major cuts and chart successes to his name, Theo has quickly become one of the most sought-after writers working across the global pop and dance space.

His latest work includes co-writing Tiësto’s single Don’t Lose Your Head feat. Olivia Sebastianelli, MK feat. Poppy Baskcomb’s Zone, and Calvin Harris feat. Jazzy’s hit collaboration Satisfy.

Continuing that success, in 2025 they joined forces with Purple Disco Machine on a rework of their classic Wonderful Life which topped the German Official Charts and reached the top 5 of the national airplay chart.

As a songwriter, Theo’s credits span some of the biggest names in music including Calvin Harris, Måneksin, MK, Louis Tomlinson, Hurts, Ellie Goulding, and more. Recent highlights include Cian Ducrot’s Who’s Making You Feel It, Shalalala and Little Dreaming; Sebastian Schub’s Scared of Screaming; Calvin Harris & Ellie Goulding’s Free; and Ruti’s I’ll Be Your Friend, alongside currently working with artists such as Teddy Swims, Muse, Rose Gray, Paloma Faith, and Silva Bumpa.
