georgios frangulis moved into sharper view at the US Open when Aryna Sabalenka reached the women’s singles final on September 12. He watched from the stands while the No. 1 seed played Elena Rybakina, turning a relationship detail into part of the tournament’s public backdrop.
Frangulis is a Brazilian entrepreneur who founded Oakberry in 2016, after studying law in Brazil without finishing the degree or taking the bar exam. Oakberry sells açaí bowls, smoothies, and more, and now has hundreds of stores in dozens of countries, which explains why his name has travel beyond tennis circles.
Oakberry and Miami, Florida
January 2024 is the point where the overlap between business and tennis began to matter publicly: Sabalenka became an ambassador for Oakberry and met Frangulis then. The relationship went public in April 2024, and the couple’s main base is in Miami, Florida, which has kept him close enough to appear regularly in her orbit during major events.
Sabalenka described the sequence bluntly in 2024: “We signed the contract, then we got to know each other. Somehow, we ended up being together.” That line matters because it puts the relationship on a work-to-personal timeline rather than a simple celebrity-spotting narrative.
August 2016 and October 2016
August 2016 brings a different part of Frangulis’s story into focus. He was diagnosed with thyroid cancer that month and had surgery in October 2016 to remove a four-centimeter nodule, a detail that gives the profile more weight than a standard partner profile usually carries.
October 2016 was also the month he tied the knot with Isabella “Beh” Armentano, before the later relationship with Sabalenka. Sabalenka said in 2024 that she and Konstantin Koltsov were still together when she first met Frangulis, then later said they were no longer together when Koltsov died; that sequence is the part that makes the timeline harder than a clean public-romance story.
January 2026 to two months later
January 2026 added the clearest public nudge toward the engagement. At the Brisbane Open, Sabalenka said, “Thank you to my boyfriend. Hopefully soon I can call you something else.” Two months after that comment, Frangulis proposed, and Sabalenka wrote, “I can finally call him something else… FIANCÉ.”
The result is straightforward: the US Open run did not create the relationship, but it made the pair more visible at a moment when Sabalenka was already on a championship stage. For readers trying to place Frangulis, the useful takeaway is not just that he is her fiancé; it is that he is a founder, a cancer survivor, and a public part of her tournament presence, with the engagement now sitting on top of a timeline that started in January 2024 and became official in April 2024.
