Witt started playing golf in 2008 and is based at Golf Club Hubbelrath near Düsseldorf. Her mentors include fellow Hubbelrathian Sandra Gal and footballer Lars Bender, whom she met at a pro-am.[1]
Witt joined the German National Team in 2018, and won the bronze at the 2018 European Young Masters with the mixed German team.[4] She finished tied 4th at the 2018 Irish Girls U18 Open Stroke Play Championship at Roganstown Golf Club, five strokes behind winner Kajsa Arwefjäll.[5]
Witt turned professional in early 2022 after finishing tied 12th at the LET Q-School, which earned her a spot on the 2022 Ladies European Tour. In only her second LET start as a professional she shared the lead after the first round at the Aramco Saudi Ladies International, and ultimately finished in a tie for 10th.[9] Her best finish in her rookie season was a tie for 3rd at the Big Green Egg Open, two strokes behind winner Anna Nordqvist.
In 2023, she recorded several top-10s and again came close to securing a maiden title at the VP Bank Swiss Ladies Open, where she shared the lead with compatriot Alexandra Försterling after the 17th hole in the final round, but after dropping a shot on her final hole ultimately finished in a tie for 3rd.[10]
