Georgios Frangulis, the entrepreneur boyfriend of world No. 1 Aryna Sabalenka, has become a familiar presence courtside during her 2025 US Open campaign.
The founder and CEO of Oakberry, Frangulis, recently opened up about his relationship with the tennis superstar, revealing how he supports her through triumphs and defeats.
How Does Georgios Frangulis Help Aryna Sabalenka Deal With Losses?
During a recent interview, Frangulis, a Brazilian of Greek descent, explained his approach to supporting Sabalenka after tough court losses.
He told Clay, “I just say that I love her and, ‘on to the next one.’ She’s used to losses, though thankfully, she’s more used to winning. It’s all about showing support and reminding her that tomorrow is another day.”
Frangulis emphasized the mental challenges tennis players face. “Tennis is probably the toughest sport in the world – you’re out there alone, and in the end you lose more often than you win. The key is letting her know I’ll always be there for her.”
This support has proven valuable considering Sabalenka’s recent heartbreak in major tournaments. Despite holding the top ranking, she suffered painful losses in 2024’s biggest events. She reached the finals at the Australian Open, losing to Madison Keys, and the French Open, falling to Coco Gauff in 2025. At Wimbledon, her campaign ended in the semifinals against Amanda Anisimova.
The couple first appeared together publicly in April 2024, just one month after the tragic death of Sabalenka’s former boyfriend, Konstantin Koltsov, who died by suicide in March 2024.
Frangulis isn’t shy about expressing his feelings publicly. When Sabalenka captured the 2024 US Open title, he posted to Instagram, “I’m in love with the Queen of NY”.

Beyond tennis, Frangulis has built his own impressive business empire. He founded Oakberry, an acai bowl company that has exploded across the United States. The company’s growth trajectory has been remarkable, with reports indicating it raised $67 million in capital in early 2024.
What Did Aryna Sabalenka Say About Georgios Frangulis Giving Her Tennis Tips?
Following her Round 4 victory over Cristina Bucsa at the 2025 US Open, Sabalenka was asked whether Frangulis has been giving her advice on tennis. She said, “I’m glad he is not giving me tennis advice. But he is always there to support me, and it means a lot.”
Sabalenka expanded on how important his presence has become. “It’s very important for me and I am really happy to have him by my side always supporting doing his stuff outside of tennis community and bringing the best support for me. That’s why I am able to bring my best tennis,” Sabalenka asserted.
Now the defending champion heads into familiar territory. In a repeat of the 2024 final, Sabalenka will face home favorite Jessica Pegula in the first semifinal. The other semifinal features a compelling matchup between the resurgent Naomi Osaka and No. 8 seed Amanda Anisimova.
