Early Life and Background
Gui Santos was born on 22 June 2002 in Brasília, Brazil. He grew up immersed in basketball due to his family’s deep connection to the sport. His father, Deivisson, played professionally in the NBB for five seasons, while his mother, Lucineide, also played basketball competitively. This family legacy provided Santos with early exposure and foundational training in the sport from a young age.
Santos began playing basketball at a young age and quickly stood out among his peers. He participated in several elite youth development camps, including Basketball Without Borders, a FIBA and NBA camp held in Medellín, Colombia, which brought together 64 prospects from Latin America. He also attended the FIBA Americas Youth Elite Camp in Campinas, Brazil, at the end of 2018, further accelerating his development.
Path to Professional Basketball
Before turning professional, Santos established himself as one of Brazil’s most promising young basketball talents through international competitions. He represented Brazil at the 2019 FIBA South America Under-17 Championship in Chile, where he helped his nation secure the gold medal. Santos scored 27 points against Argentina in the final, showcasing his ability to perform in high-stakes situations. In April 2021, he was named to the World Team for the Nike Hoop Summit, one of the most prestigious international high school basketball events.
Gui Santos Career
Minas (2018–2022)
Santos made his professional debut with Minas of the Novo Basquete Brasil (NBB) during the 2018–19 season at just 16 years of age. He averaged 6.7 points, 5.7 rebounds, 2.5 assists, and 10.5 efficiency over 23.0 minutes per game in his debut season. Despite his youth, his performance demonstrated advanced skill and maturity beyond his years. Because Santos was still attending school, he was unable to follow the adult team’s full routine during that initial campaign.
In the 2019 Basketball Development League (LDB), Santos emerged as the leader of the Minas team. At 17 years old, he posted impressive averages of 14.5 points, 6.4 rebounds, and 2.6 assists in the Under-20 championship. By 2019, he had already become part of the club’s senior roster, appearing in three NBB games during the 2018–19 season against Joinville, Vasco, and Sesi Franca. During the 2019–20 NBB season, Minas coach Léo Costa granted Santos a larger role with the team, accelerating his development.

Santos declared for the 2022 NBA draft and was selected by the Golden State Warriors with the 55th overall pick in the second round.

Less than three weeks later, on 25 March, he established a new career best with 31 points, along with three rebounds, two steals, one assist, and one block, in a 109–106 victory over the Brooklyn Nets.
