Who Is Dimitris Giannakopoulos?
Born on June 22, 1974, in Athens, Dimitris is the only son of Pavlos Giannakopoulos, the founder of Vianex. He stepped into leadership roles early, becoming first vice president in 2004 and later president and CEO. Today he leads Vianex while maintaining majority control of Panathinaikos B.C., one of the most decorated clubs in Greek and European basketball.
He is known for his direct, sometimes fiery public style, especially when defending the club. That same intensity has helped keep Panathinaikos competitive at the highest levels of the EuroLeague while the family business quietly expands.
Where Does the Wealth Come From?
The core of the fortune sits in pharmaceuticals. Vianex remains Greece’s largest domestic pharmaceutical producer, with strong manufacturing capacity, partnerships with global firms such as Eli Lilly, and a growing export footprint. Additional stakes, including a significant share in Superfoods (health supplements), add diversification.
Sports ownership plays a smaller but highly visible role. The family has invested hundreds of millions of euros into Panathinaikos over the decades. While the club generates revenue and prestige, it functions more as a passion project and brand amplifier than the primary wealth engine.
Key pillars of the portfolio include:
- Majority control and leadership of Vianex
- Ownership of Panathinaikos B.C.
- Stake in Superfoods and other related health-sector interests
- Media and various private investments through the broader DPG group
