The Business Manager Role: From Real Madrid to the NBA Draft

The trajectory of Luka Doncic’s career required a dedicated hand to manage the off-court affairs, and that hand belonged to Mirjam Poterbin. When Luka made the monumental decision to move from Slovenia to Spain at the age of 13 to join Real Madrid’s basketball program, Mirjam was right there to guide him. This move was the first major step in her transition from a Slovenian public figure to a full-time sports business manager.

Her experience as an entrepreneur—reportedly a beauty salon owner in Slovenia—equipped her with the foundational skills necessary to handle contracts and negotiations in the complex European basketball landscape. She took charge of his business decisions and affairs, allowing the young prodigy to focus solely on developing his game. This arrangement continued through his rise to EuroLeague MVP and his eventual selection by the Dallas Mavericks in the 2018 NBA Draft. Mirjam was a constant presence, ensuring her son’s off-court life was stable and his financial future was secured.

The Trademark Conflict and Its Quiet Resolution (Updated 2025)

Perhaps the most high-profile and complex aspect of Mirjam’s involvement in Luka's career was the legal conflict over the "LUKA DONCIC 7" trademark. This dispute, which garnered significant media attention in 2022, centered on the ownership of the trademark she had registered during his rookie season.

Luka Doncic officially filed a petition to cancel the trademark, seeking to gain full control of his own name and brand as his international profile exploded. The situation created a public narrative of a difficult family split, though both parties maintained a respectful silence on the specifics. However, the most recent and critical update is that the dispute has been quietly resolved. In a move that avoided a protracted public court battle, the Mavericks superstar and his mother settled the legal conflict, suggesting a successful negotiation and a restoration of their business relationship to a more amicable footing. This resolution allows Luka to move forward with full control over his brand identity, while preserving the deep personal bond with his mother.
