Frangulis has generally maintained a lower public profile than his fiancée, but his work in the food and franchise industry has made him a recognizable business figure in Brazil and beyond. Forbes Brasil described him as a São Paulo-born founder and CEO of Oakberry and reported that he has Greek family roots.
Frangulis’s education and background
According to Forbes Brasil, Frangulis studied law at the Fundação Armando Alvares Penteado, commonly known as FAAP, and graduated in 2014. He said he did not go on to take the Brazilian bar examination, instead moving into business.

#1 Best Overall
Public business coverage identifies him as Brazilian and São Paulo-based. An exact age has not been reliably established in the sources available for this profile, so it is better not to attach a specific number to his biography.
What is Oakberry?
Oakberry is a Brazil-founded healthy-fast-food franchise focused primarily on açaí. Its official franchise framework identifies Frangulis and Haidar as the company’s founders in 2016 and describes a menu built around customizable bowls and smoothies. Customers can add ingredients such as fruit, granola, honey, chia, and whey protein.
The company’s model combines a relatively simple menu with franchising, branding, and international expansion. Oakberry began expanding outside Brazil, including with locations in Florida in the United States, and later entered additional markets. However, the official framework available for this background is historical rather than a current store directory, so older store totals and country counts should not be treated as up-to-date.
Frangulis has also spoken publicly about Oakberry’s international growth and supply chain. In his interview with Forbes Brasil, he linked the brand’s expansion to the international popularity of açaí and emphasized sustainability as an important part of the business and its sourcing.
Readers curious about the food category can try an açaí bowl mix at home. This is a related grocery option—not an Oakberry product and not an item endorsed by Frangulis or Sabalenka—and availability can vary by location.
How did Georgios Frangulis and Aryna Sabalenka meet?
The couple has not publicly provided a detailed account of how they first met. Their relationship became publicly visible in May 2024, when Sabalenka shared photos and video of herself with Frangulis in Italy. Women’s Tennis Blog reported that the post made their relationship Instagram-official on May 19, 2024.
Frangulis was subsequently seen supporting Sabalenka at tournaments, including from the player box. The couple also shared occasional public moments on social media, while keeping many details of their private life out of the spotlight.
Reports differ or speculate about the exact beginning of their private relationship. The confirmed public timeline begins with the May 2024 social-media reveal; there is no need to assign an earlier dating date without a direct confirmation from the couple.

Frangulis proposed to Sabalenka on March 3, 2026. Sabalenka announced their engagement publicly on March 4, 2026, ahead of the Indian Wells tournament.
Rank #3
Her announcement included the caption, “You & me, forever ♾️ 3.3.26.” The date refers to the proposal, while March 4 is the date on which the engagement became public. Reuters, in a report carried by Channel NewsAsia, identified Frangulis as Oakberry’s CEO and said the couple had been dating since 2024.
A joint video of the proposal showed a romantic setting decorated with flowers and candles. Sabalenka later wrote that she could finally call Frangulis her fiancé.
What is known about Aryna Sabalenka’s engagement ring?
Media coverage has described Sabalenka’s ring as featuring a large oval diamond set on a platinum band with emerald accents. Elle reported that jewelry designer Isabela Grutman collaborated with Frangulis on the design and that emeralds were chosen because they are Sabalenka’s favorite stone.
Some lifestyle reports have estimated the center diamond at approximately 12 carats and placed the ring’s possible value near $1 million. Those figures are media estimates, not a publicly documented gemological appraisal. The exact carat weight, quality, and value should therefore be treated as unconfirmed unless the designer or an independent appraiser provides documentation.
Rank #4
Who is Aryna Sabalenka?
Sabalenka is a Belarusian professional tennis player and one of the most prominent athletes in women’s tennis. The WTA profile lists her birthday as May 5, 1998, and identifies her as a four-time Grand Slam singles champion. The profile consulted for this article also listed her as the world No. 1 in women’s singles.
The WTA reported in July 2026 that Sabalenka had reached 100 weeks as world No. 1, placing her among the ten women who have spent the most time at the top of the rankings since the computer rankings began. Her success helps explain the level of interest in her engagement, but Frangulis’s own career is separate from her tennis achievements: he is best known professionally for building Oakberry.
Are Georgios Frangulis and Aryna Sabalenka married?
No reliable wedding date or marriage has been established in the sources used for this profile. Frangulis should be described as Sabalenka’s fiancé, not her husband. The couple’s engagement was announced in March 2026, and any later wedding plans would need to be confirmed by the couple or a dependable source.
