A Short Note from Your Future Lead

Ioannis Georgopoulos , running the Finance team at Entrix:

"Hello future colleague, this is Ioannis!

I joined Entrix with a purpose to build & lead the Finance function, with scalability in mind.

My career started in the commodities trading space, at Archer Daniels Midland Company, where I was given the unique opportunity to get proper skin-in-the-game on derivatives & physical markets, develop a very strong commercial acumen, and eventually built a small division from the ground up.

In 2020, I was nominated a “Global Trade Leader” by the Hinrich Foundation, and was given a merit-based scholarship to pursue my MBA at INSEAD in Singapore.

Post-MBA, I moved to Switzerland and joined RBI (a 3G Capital Private Equity Investment Portfolio Company), where I served in advisory and eventually headed the Strategic Finance for EMEA region.

I have worked & studied in Greece, Germany, Netherlands, France, Belgium, Singapore and Switzerland over the last 15 years. I am actively involved in the Swiss Startup Nights Association, but love hiking and travelling when time permits!

As a leader, I deeply value honesty, pragmatism, resilience and big-picture thinking. I make sure my team members are feeling involved, appreciated and have freedom in the way they work. That sets the tone for a collaborative, good-spirited team.

If you’re excited about joining a dynamic and supportive team where your contributions truly matter, I warmly encourage you to consider joining us. We’d love to have you onboard and grow together!”

Best, Ioannis
