Georgios Frangulis became widely known to tennis fans as Aryna Sabalenka’s boyfriend, but his public story began long before he appeared in the world No. 1 player’s tournament box. The Brazilian entrepreneur is the co-founder and chief executive of Oakberry, an international açaí business that grew from a single São Paulo store into a global franchise network.
His relationship with Sabalenka developed after Oakberry signed the Belarusian tennis star as a brand ambassador. They began dating in 2024, supported one another through demanding professional schedules and announced their engagement in March 2026. As of July 2026, Frangulis is therefore more accurately described as Sabalenka’s fiancé rather than her boyfriend.
Beyond the relationship, he has built a career spanning food retail, international franchising, motorsport, clothing and sports investment. Some details about his finances and private family life remain undisclosed, but his business record and public role beside Sabalenka are well documented.
Early Life and Family Background
Georgios Frangulis was born on September 9, 1988, in São Paulo, Brazil. He was 37 years old as of July 2026. He is Brazilian by birth and nationality, while his family has Greek roots.
His grandfather, who was also named Georgios, came from Thessaloniki, Greece. Frangulis has described growing up with Greek traditions, religious influences and a strong sense of family identity despite being raised in Brazil. That heritage later became visible in his tattoos, clothing choices and business projects.
His father is named Eleftherios Frangulis. Much less is publicly known about his mother, siblings or wider family, and he has not turned his relatives into regular public figures. Most reliable profiles focus on his business work, racing interests and relationship with Sabalenka rather than the private details of his upbringing.
Frangulis’s dual cultural background helps explain why he is often called Brazilian-Greek. That description refers to his Brazilian nationality and Greek ancestry, not to a confirmed Greek birthplace.
Education and Early Ambitions
Frangulis studied law at Fundação Armando Álvares Penteado, commonly known as FAAP, in São Paulo. He completed his studies around 2014 but chose not to pursue a conventional legal career.
He has said that he did not collect his diploma or complete the examination required to practise law in Brazil. By that point, his ambitions had shifted toward entrepreneurship. The education still gave him experience with contracts, negotiation and structured decision-making, all of which later became useful as he expanded an international company.
After university, Frangulis moved to Miami and explored real-estate investments. He borrowed money, purchased an apartment and became involved in a land project with a friend. Currency changes and difficult market conditions disrupted those plans, forcing him to sell the investments and repay what he owed.
The setback did not end his interest in business. Instead, it pushed him toward a product he understood through his Brazilian upbringing: açaí. He believed the fruit could be presented internationally through a quick-service model that combined convenience, customization and an image associated with fitness and healthy living.
Founding Oakberry
Frangulis co-founded Oakberry in 2016 with Renato Haidar. The first store opened in São Paulo, serving açaí bowls and smoothies in a format designed to work like a fast-food operation while emphasizing fruit, toppings and customizable portions.
The founders entered a market in which açaí was already popular in Brazil but less standardized internationally. Their strategy focused on recognizable branding, a consistent menu and franchising. That approach allowed the company to expand without relying entirely on stores owned and operated from its central office.
Oakberry grew first across Brazil and then entered markets in North America, Europe, the Middle East, Asia and Australia. By the middle of the 2020s, published company figures placed the chain in more than 50 countries, with hundreds of stores operating or under development.
Frangulis became the public face of that expansion. His work included fundraising, franchise growth, marketing partnerships and relationships with athletes. Oakberry attracted a major investment connected to BTG Pactual in 2023, giving the company additional capital for international development.
The company also built a production operation in Pará, near the region where açaí is harvested. Oakberry has promoted relationships with Amazon-area suppliers and cooperatives, although the environmental and social effects of any rapidly growing food chain require continued scrutiny rather than acceptance of marketing claims alone.
By 2025 and 2026, Frangulis was describing Oakberry as a business generating revenue above one billion Brazilian reais. Those figures indicate substantial commercial scale, but Oakberry is privately held, so its full accounts, ownership percentages and profit margins are not broadly available.
Motorsports and Other Business Interests
Frangulis has maintained a serious interest in motor racing alongside his work at Oakberry. He competed in Porsche racing categories, including Porsche Carrera Cup Brasil and international events connected to the manufacturer’s one-make series.
Public racing databases credit him with more than 100 starts, several victories and multiple podium finishes. His participation was more than a ceremonial appearance by a company executive, although business remained his primary professional focus.
Racing also became part of Oakberry’s promotional identity. Cars, sponsorships and sports events gave the brand exposure among audiences interested in performance and lifestyle products. Frangulis’s personal involvement made that connection more credible than a standard sponsorship arranged only by a marketing department.
He later expanded into football investment by becoming associated with Le Mans FC in France. Reports described him as an investor and branding executive connected to the club. The city’s famous link to endurance racing made the project a natural extension of his sporting interests.
In 2026, he also launched The Gride, a clothing brand influenced by his Greek ancestry. The name combines ideas associated with Greece and pride, while the designs draw from symbols, religion, family history and Frangulis’s own visual style.
How Georgios Frangulis Met Aryna Sabalenka
Frangulis met Aryna Sabalenka through Oakberry’s commercial relationship with the tennis player. The company announced Sabalenka as a brand ambassador in January 2024, although their first discussions and meetings appear to have taken place during the previous autumn.
They reportedly met in Dubai while the partnership was being arranged. Their initial connection was professional, not a romance that had been disguised as a sponsorship. As they spent more time together, the relationship became personal.
By the spring of 2024, Frangulis was appearing in Sabalenka’s player box. They were seen together during the Madrid Open and later attended the Formula 1 Emilia-Romagna Grand Prix. Their photographs and social-media posts gradually confirmed what fans had begun to suspect.
Sabalenka later explained that they first had a business agreement and then became a couple after getting to know each other. They have not announced an exact dating anniversary, but the relationship was clearly established by the middle of 2024.
Supporting Sabalenka Through a Difficult Period
The beginning of the relationship came during an emotionally difficult year for Sabalenka. Her former partner, Konstantin Koltsov, died in Miami in March 2024. Sabalenka said they were no longer together at the time of his death but described the loss as a tragedy.
Frangulis became part of her support system as she continued competing under intense public attention. Sabalenka has credited him with helping her enjoy life away from tennis, arranging activities and giving her emotional space after difficult matches.
That support was visible during a season that also brought major success. Frangulis watched from her box as she won the Cincinnati Open and later the 2024 US Open, where she defeated Jessica Pegula in the final. The title gave Sabalenka her third Grand Slam singles championship.
He continued attending tournaments in 2025 and 2026. His role remained personal rather than technical. Sabalenka’s coaches, trainers and medical staff handled her performance, while Frangulis appeared as a partner who travelled when possible and helped her separate her private life from the pressure of elite competition.
Their Engagement
Sabalenka and Frangulis began making public jokes about marriage during 2025. At the US Open, a proposal involving spectators prompted Sabalenka to look toward him and laugh about the possibility. In January 2026, after winning in Brisbane, she openly suggested that she hoped she would soon be able to call him something other than her boyfriend.
Frangulis proposed on March 3, 2026. The couple announced the engagement through a joint social-media video showing an outdoor setting decorated with flowers and candles.
The engagement ring features an oval diamond reported to be about 12 carats, accompanied by emerald details. Frangulis worked with Miami jeweler Isabela Grutman on the design. Sabalenka had previously joked that a small stone would not suit her hand, and the finished ring became a highly visible part of the announcement.
Published estimates have placed the ring’s value at several hundred thousand dollars or more, but the couple has not disclosed its purchase price. Any exact valuation without information about certification, clarity, color and commercial terms remains speculative.
As of July 2026, they had not married. Sabalenka has discussed Greece as a possible location for a summer 2027 wedding, but no final date or venue has been publicly confirmed.
The Business Connection Between Them
Sabalenka’s relationship with Frangulis has continued alongside her formal work with Oakberry. In 2024, the company introduced a signature product called the Power Serve Bowl by Sabalenka ahead of the US Open.
The partnership gives Oakberry access to one of the most recognizable athletes in women’s tennis. Sabalenka’s global tournament schedule and large social-media audience fit the company’s international image, particularly its association with sport, energy and active lifestyles.
At the same time, the relationship creates questions about where personal and commercial interests meet. Neither Sabalenka nor Frangulis has publicly detailed how her contract changed after they became a couple or whether it was renegotiated following their engagement.
There is no evidence that the partnership is improper. Still, readers should distinguish between confirmed business arrangements and assumptions about their private finances, ownership or decision-making.
Personal Life and Public Image
Frangulis presents himself publicly as energetic, ambitious and comfortable around sport. His social-media presence includes business travel, racing, Oakberry events, clothing and photographs with Sabalenka.
He is more publicly visible than many partners of professional athletes because his own companies depend partly on marketing and personality. Even so, he has kept some areas of his life private. Detailed information about earlier relationships, close family members and personal property has not been publicly confirmed.
His appearances with Sabalenka usually show a relaxed contrast to her intense competitive image. They share travel photographs, jokes and affectionate moments, while avoiding detailed public discussions of every disagreement or decision.
That balance has shaped his reputation among tennis fans. He is viewed less as a celebrity boyfriend without an independent identity and more as an established entrepreneur who became part of Sabalenka’s personal circle.
Net Worth and Income Sources
Georgios Frangulis’s exact net worth is not publicly confirmed. Online estimates often place his wealth in the tens of millions of dollars, but those figures are not supported by full financial records.
His main source of wealth is likely his ownership interest in Oakberry. He may also earn money through executive compensation, franchise growth, investments, motorsport-related partnerships, Le Mans FC and The Gride.
Company revenue should not be confused with personal wealth. Oakberry’s reported annual sales belong to the business and must cover employees, suppliers, franchise operations, investors, taxes and expansion costs.
Without verified information about Frangulis’s ownership percentage, liabilities and outside assets, a precise net-worth figure would create false certainty. The available evidence supports describing him as a financially successful entrepreneur, not assigning him an exact fortune.
Recent Work and Current Status
By July 2026, Frangulis remained chief executive of Oakberry while supporting its continued international expansion. The company was operating across dozens of markets and pursuing additional stores through franchising and partnerships.
He was also developing The Gride and maintaining his involvement in sport-related investments. His racing appearances appeared less central than during earlier years, though motorsport remained part of his personal identity.
His engagement to Sabalenka brought added international attention. He continued appearing at major tennis tournaments, including events where Sabalenka competed for Grand Slam titles and the world No. 1 ranking.
The couple appeared to divide their lives among tournament destinations, Miami, Europe and business travel. They had announced no children and no completed wedding plans as of July 2026.

Conclusion
Georgios Frangulis has built an identity that stands apart from his relationship with Aryna Sabalenka. Oakberry made him an international entrepreneur, while racing, football investment and fashion broadened his public profile.
His connection with Sabalenka began through business and developed during a demanding period in her life. Their relationship became visible not because of a single announcement, but through months of tournament appearances, travel and mutual support.
The engagement moved him from boyfriend to prospective husband, though the couple has not rushed to disclose every wedding detail. That restraint fits the way they have handled much of their relationship: openly affectionate, commercially connected and still protective of important private decisions.
Frangulis now occupies an unusual place beside one of tennis’s leading players. He is part of her support system, but he remains a founder with his own career, risks and ambitions.
