His father, Claudio Ricardo Wild, manages several tennis academies in Brazil, and his mother, Gisela Christine Seyboth, works as a dentist. He has a sister named Luana. Seyboth Wild is of paternal Romanian and Russian descent, while his mother is of German heritage.
He picked up a racket at the age of four with the help of his father, who introduced him to the sport in a tennis-rich household. By 14, Seyboth Wild moved to Rio de Janeiro to chase a professional career, a step that shaped his disciplined routine and competitive mindset.

Path to Tennis
Seyboth Wild built a strong foundation on the ITF junior circuit, posting an 88–36 singles win-loss record.

He also reached the semifinals at Roland Garros and competed in junior doubles finals at both majors.
His junior success opened doors to the senior game, and he made his ATP main-draw debut at the 2018 Brasil Open on a wildcard. In November 2019, at 19, he won his first Challenger title in Guayaquil, breaking into the world’s top 300 and establishing himself as the third-best Brazilian in the rankings behind Thiago Monteiro and João Menezes.
