Who Is Georgios Frangulis? Aryna Sabalenka’s Fiancé Built a $100M Empire While She Conquered Tennis

When Aryna Sabalenka defeated Naomi Osaka at the 2026 French Open to advance to the quarter-finals, one face in the crowd carried as much story as anyone on the court. Georgios Frangulis — her fiancé, her steadying presence during the worst period of her life, and by most financial estimates, the wealthier half of one of sport’s most compelling new power couples — watched from the sidelines as his future wife continued her pursuit of a maiden Roland Garros title.

Understanding who Frangulis is adds an entirely different dimension to Sabalenka’s 2026 story.

The Entrepreneur Who Walked Away From Law and Built a Global Empire

Born and raised in São Paulo, Brazil, Frangulis began his academic career studying law at FAAP — Fundação Armando Alvares Penteado — in 2014. He completed the coursework but deliberately chose not to sit for the bar exam, telling Forbes Brazil in 2023 that he always knew law was not his destination.

That clarity of direction proved consequential. In 2016, he co-founded Oakberry alongside Renato Haidar, building a superfood brand centered on acai — the nutrient-dense Amazonian fruit that had long been a Brazilian staple but had not yet found its global commercial form.

By 2026, Oakberry operates more than 700 stores across over 40 countries. The company’s growth from a single Brazilian concept to a multinational health food brand represents one of the more remarkable entrepreneurial trajectories in the food and wellness industry over the past decade.

Frangulis has cited his Brazilian roots and the cultural significance of acai in his home country as the foundational inspiration — a local passion scaled through disciplined international expansion.

Sabalenka Became Part of the Brand Before She Became Part of the Family

The personal and professional overlapped early in their relationship. Sabalenka became an Oakberry brand ambassador in 2024 — the same year she and Frangulis first appeared publicly together. That arrangement reflected a genuine alignment rather than a transactional endorsement: a health-focused athlete representing a health-focused brand whose founder she was simultaneously falling for.

It also meant their relationship had dual visibility — both in tennis coverage and in business media — giving it a different kind of public footprint than most athlete-partner stories generate.

A Love Story That Began in Grief

The timeline of their relationship carries emotional weight that the engagement photos alone do not convey. Sabalenka’s former partner, Konstantin Koltsov, died in March 2024 under circumstances that placed her at the center of significant media scrutiny and personal anguish. Frangulis entered her life during that exact period.

Their first confirmed public sighting came in April 2024 at the Mutua Madrid Open — weeks after Koltsov’s death. He appeared again at the Cincinnati Masters in August and the US Open in September, a visible progression that mapped his growing presence in her life against the backdrop of her professional calendar.

In an August 2024 interview with PEOPLE, Sabalenka described how he kept her emotionally functional during that stretch — making sure she was doing enjoyable things and remaining consistently present when withdrawal would have been easier.

That kind of support, offered at that specific moment, explains the depth of their bond in ways that a conventional celebrity love story simply does not.

The Proposal That Sabalenka Accidentally Telegraphed

The engagement announcement in March 2026 was formally a surprise, though Sabalenka had inadvertently signaled it herself. During her Australian Open trophy speech in January 2026, she thanked her boyfriend and added, with evident hope, that she would soon be able to call him something else.

Two months later, Frangulis proposed in a private outdoor setting arranged with candles, flowers, and white rose petals around a pool. Sabalenka posted the moment on Instagram — including the exact second he went down on one knee — with a caption that delivered on the Australian Open hint perfectly.

The Financial Picture Behind the Partnership

Frangulis’s net worth, according to a 2026 Hello! report, sits between USD 75 million and USD 100 million, built primarily through Oakberry’s expansion. Sabalenka’s estimated net worth ranges from USD 22 million to USD 27.4 million, generated through prize money, endorsements, and her status as the world’s top-ranked women’s tennis player.

Their combined wealth — between USD 97 million and USD 128 million — makes them one of the most financially substantial couples in professional tennis, which itself is notable given that Frangulis built his fortune entirely outside the sport.

Beyond tennis, Frangulis competes in motorsports, having participated in Porsche GT3 Cup Challenge races — a detail that rounds out a profile defined by competitive drive extending well beyond the boardroom.

What Their Story Signals for Tennis Culture

The visibility of supportive, financially independent partners in elite tennis has grown significantly. Frangulis represents a new archetype in that space — not a former athlete, not a celebrity, but a self-made entrepreneur with a global brand who exists entirely on his own terms while actively supporting a partner at the top of her field.

As Sabalenka advances deeper into Roland Garros 2026, that partnership dynamic will only draw more attention. Whether she captures the one major title still missing from her collection, she already has something harder to win — someone who showed up during her worst year and stayed.
