Who are we?
We are entrepreneurs, operators and partners.
Oreka Studio was born from a shared belief that founders and teams deserve more than advice, they deserve true partners.
We created Oreka Studio to fill a gap we kept seeing between strategic thinking and hands-on execution, between creative potential and operational reality. Over the years, we had each walked our own entrepreneurial paths: launching companies, leading teams, advising founders, and navigating complexity across industries.
Our paths crossed while supporting different startups and Oreka became the natural next step: a studio where we could channel our experience, networks, and creative energy into helping meaningful companies grow with clarity, courage, and balance.

In 2025, Thierry published a book on entrepreneurship titled "Get Up, Startup" available for free here.
