Leadership team
Vasilis Sotiroudas,
Co-Founder & Chief Commercial Officer

As a child, Vasilis wandered the marbled hallways of the Ministry of Agriculture, where his father, Athanassios, introduced Greece to
the fumigants that would improve the country’s crop yield and safety. Years later, after studying agronomy at university and working with respected scientists in the field, Vasilis returned to the family business to work alongside his father. Bringing research and technology together, he synthesized the solution that helped solve the greatest challenge of modern farmers – crop loss control – and began cultivating the vision that is Centaur. Now with children of his own, his work is an extension of his family’s legacy. Adding precision and control to the world’s food supply chains, he hopes to improve global food security and transparency so all families can enjoy the benefits of a healthy and robust diet.


Sotiris Bantas,
Co-Founder, President & CEO

Raised in the rawhide trade, an ancient profession tied closely to Greece’s rural economy, it was generally expected Sotiris would follow suit like the generations before him. But his love for numbers and circuits led him to pursue engineering and a career in semiconductors, growing his design automation software startup to multi-million dollar accounts in Silicon Valley and Japan. Returning to his roots, Centaur allows him to create innovative technology that makes food production safer and ultimately more democratic – proof that creative solutions can help crack tough humanitarian problems. Sotiris has a degree in Electrical Engineering and a Ph.D. in semiconductor design. He holds four US patents and has several pending.
