Aryna Sabalenka Boyfriend: Inside Her Relationship With Oakberry Founder Georgios Frangulis

World No. 2 tennis star Aryna Sabalenka continues to command international attention both on and off the court as she builds momentum through the 2026 summer hard-court swing. Beyond her blistering forehands and Grand Slam ambitions, fans consistently turn their eyes toward her player box, where her partner, Brazilian entrepreneur Georgios Frangulis, remains a constant pillar of support.

The Entrepreneur in the Box: Who Is Georgios Frangulis?

The spotlight on Aryna Sabalenka’s personal life shifted dramatically in early 2024 when she connected with Georgios Frangulis, a prominent Brazilian businessman best known as the founder and global CEO of Oakberry, an international açai and superfood brand. The relationship began evolving publicly around the time Oakberry secured an official commercial partnership with Sabalenka, bridging her elite athletic career with his expanding business empire.

Since going public during the 2024 European clay-court season, the couple has been visible across social media and public events. Frangulis, an avid motorsport enthusiast and former driver, frequently trades business boardrooms for courtside seats. His presence in Sabalenka's box during high-stakes finals has drawn frequent commentary from broadcasters, who note the grounded stability he brings to her high-intensity tour schedule.

High-Stakes Support: Balancing Elite Tennis and Public Attention

Maintaining peak performance on the WTA Tour requires immense mental fortitude, and Sabalenka has frequently highlighted the importance of her immediate inner circle. Throughout the 2025 season and into August 2026, Frangulis has been a regular fixture at key tour stops, traveling from Melbourne to London and across North America.

Their dynamic extends beyond emotional support to shared lifestyle and brand endeavors:

• Global Travel Integration: Frangulis frequently coordinates his international corporate obligations around Sabalenka’s major tournament calendar.
• Brand Synergy: Sabalenka’s role as a global brand ambassador for Oakberry has created major marketing campaigns, intersecting professional sports with international wellness trends.
• Courtside Presence: Frangulis’ steady encouragement alongside head coach Anton Dubrov has become a familiar fixture during crucial late-stage matches.

US Open 2026 Outlook and Off-Court Momentum

As of August 10, 2026, Sabalenka is finalizing her preparations for the 2026 US Open in Flushing Meadows, seeking to capture another major title on hard courts. Observers across the sport note that her off-court stability has played a measurable role in her consistent top-tier WTA rankings and deep tournament runs over the last two years.

With her personal life grounded alongside Frangulis and her game delivering elite results, Sabalenka remains one of the most formidable and marketable figures in modern tennis. As the 2026 season heads toward its final Grand Slam stretch, her combination of power on the court and high-profile life off it keeps her squarely in the global headline spotlight.
