“I can say we were always a Greek family, in how we see the world, our values, and the way I was raised. I feel 100% Greek,”
#2: He Went to Law School, but Decided to Become an Entrepreneur
Although Frangulis studied law at Fundação Armando Alvares Penteado, a private university in Sao Paolo, he wound up becoming an entrepreneur instead, founding Oakberry, an acai-based food brand that has spread across the world.
As he explained in an interview with Forbes Brazil in 2023, he knew his future wasn’t in law:
“I always knew I wouldn’t be a lawyer. What I really wanted was to be an entrepreneur.”

In the aforementioned interview with Forbes Brazil, Frangulis opened up on his first marriage to a woman named Isabella Armentano in 2016.
As he explained, the two wed months after he was diagnosed with Thyroid cancer in the summer of 2016.
“I never told anyone, but in August 2016, I found out I had thyroid cancer, a four-centimeter nodule that the doctor said needed to be removed to determine the treatment.
“I got married on October 1st; I used the last money I had to pay for the wedding bar; I had surgery on October 16th and managed to open the first Oak store in São Paulo on December 6th, because I was hit by a kind of divine ray when I needed it most, and least expected it.”
#4: His “Spiritual Side” Is Important to Him

Although it’s unclear whether Frangulis is Greek Orthodox, the predominant religion in Greece, he stated in the aforementioned Forbes Brazil article that he goes to church quite a bit.
As he explained, his beliefs were influenced by both sides of his family:
“I go to church a lot, talking to God does me good. I was influenced by both branches of the family. The spiritual side has always been important to me, as well as intuition.”

In addition to his role with Oakberry, Frangulis raced as an Oakberry driver in the Porsche GT3 Cup Challenge.
Per Driver Database, he’s competed in 128 races, but hasn’t competed since 2023.
In the aforementioned Forbes Brazil interview, he opened up on racing, saying:
“The Porsche Cup races and training sessions are almost always on weekends. So, if I maintain a routine of physical training in my daily life, in addition to psychological support to cope with the pressure [therapy twice a week], I’m always prepared for the moment of driving. Getting in the car and racing is one of the few moments when nothing else matters.”
