Keynote: Built by Argonauts: Entrepreneurial Science and the People That Make It Happen

26 November 2026 - Flanders Expo

argenx started with a small team of scientists in Ghent and has grown into a global immunology company united by one purpose: transforming the lives of people living with severe autoimmune diseases. At the heart of that journey is Entrepreneurial Science: combining scientific excellence with curiosity, ownership, and the courage to turn bold ideas into impact for patients.

In this keynote, Loes Bresseleers shares how argenx works, what makes its culture unique, and what it takes to thrive in a fast-growing, innovation-driven environment. You'll learn about opportunities for early-career talent, what argenx looks for in future Argonauts, and what to expect from the hiring process. Most importantly, this session is an invitation to reflect on your own ambitions. What energizes you? What strengths do you bring? And where could your curiosity and entrepreneurial spirit take you next?

If you're looking for a place where bold ideas, ownership, and co-creation can help shape the future of immunology innovation, join us for an honest look behind the scenes of argenx.
