Early Life and Background
Ignacio Buse was born in Lima to his father Hans and his mother Betty, née Acurio. His father is a tennis coach and former player, which gave Ignacio early and consistent exposure to the sport.

The family is also of German descent through Ignacio’s great-grandfather, adding a broader international layer to his background.
Buse is the nephew of the internationally renowned Peruvian chef Gastón Acurio, a connection that has drawn additional public interest to his rising profile. He began playing tennis at the Country Club de Villa in Lima, the club where he developed his earliest skills on court. As his talent became more evident, his family supported a move abroad so he could train at a higher level.
He later relocated to Barcelona, Spain, where he joined the TEC Academy to train under former French Open champion Albert Costa. This transition to a high-performance European training environment played a key role in shaping his professional game and preparing him for the international circuit.
Path to Professional Tennis
Buse’s competitive foundation was built on the ITF junior circuit, where he compiled a 77–38 singles win-loss record and reached an ITF junior combined ranking of world No. 9 on 3 January 2022. His standout junior result came at the 2022 French Open, where he reached the boys’ doubles final alongside compatriot Gonzalo Bueno, signaling his readiness for the professional stage.
In 2023, Buse made his first move into Challenger-level competition, reaching his first Challenger doubles final in Lima in August while partnering with Jorge Panta. The following year, in 2024, he received a wildcard into the qualifying competition at the 2024 Chile Open and later advanced to his first Challenger singles final in Como, where he finished as runner-up to Gabriel Debru. These early experiences helped him move into the ATP top 250 by the end of 2024.
The year 2025 marked his true transition to the main professional ranks. He made his ATP Tour debut at the 2025 Chile Open as a wildcard, reached his first ATP semifinal at the Swiss Open, won his first ATP match against Laslo Djere, and captured his maiden Challenger title at the 2025 Neckarcup 2.0.
