Sébastien Deletaille - How Rosa became No. 1 in digital health

Sébastien Deletaille is co-founder and CEO of Rosa, the app that wants to become the digital health portal for every Belgian citizen.

After co-founding and managing Riaktr, one of the most noticed startups in the Brussels ecosystem, he is going through a deep personal crisis that is forcing him to question everything: his way of leading, his values, and what he really wants to build.

In this episode, he looks back on more than 15 years of entrepreneurial career with a rare sincerity: the mistakes we don't dare to name, the inner reconstruction, and the vision that drives him today.

On the program:

• The arrogance of the tech CEO: the taboo that no one talks about. Sébastien explains how he became convinced that he knew everything, ignored dissenting voices, and what it cost his teams and the company in concrete terms.

• 7 years of coaching to rebuild yourself. After several simultaneous slaps, he chooses to slow down and retouch his deepest workings rather than bouncing on autopilot.

• From the 31st Belgian platform to the number one in the market. How Rosa dominated an ultra-crowded industry with a patient-centric strategy.

• The non-profit organisation as a competitive advantage. Why non-profit status creates a natural membership in the healthcare world.

• The sector's resistance. Mutual insurance companies, medical software, Doctolib: Sébastien explains the outcry Rosa is facing, and why he considers them a positive signal.
