Health, set and match

From tennis to entrepreneurship

Before becoming an entrepreneur, Stanislas Niox-Chateau first made a name for himself on the tennis court. A six-time junior champion of Paris and winner of the International Junior Open at just 12 years old, he dreamed of turning professional. Born in 1987 in Paris and raised in Boulogne-Billancourt, he joined the French national youth team, but at 17, a severe back injury abruptly ended his sporting ambitions.

Instead of giving up, he chose to rebuild. In 2006, he enrolled at HEC Paris, where he strengthened his strategic and leadership skills, notably as vice-president of the school’s Junior Enterprise. His competitive mindset gradually evolved into an entrepreneurial one.

Doctolib, the unicorn transforming healthcare

After graduating, he co-founded Otium Capital in 2010, an investment fund supporting innovative startups such as La Fourchette, an online restaurant booking platform. But in 2013, he decided to switch from investor to entrepreneur and created Doctolib with Jessy Bernal, Ivan Schneider, Steve Abou-Rjeily and Thomas Landais. Their ambition? To transform access to healthcare in France.

More than a simple appointment-booking platform, Doctolib develops secure digital tools designed to improve the daily lives of both patients and healthcare professionals. For patients, this means faster access to consultations and greater transparency in their medical journey. For doctors, Doctolib helps reduce administrative tasks, optimize scheduling, and improve care coordination.

Under Stanislas Niox-Chateau’s leadership, the company experienced explosive growth. In 2019, it passed the symbolic threshold of one billion dollars in valuation, becoming a French unicorn and a European leader in digital health.

Building healthcare together

Stanislas Niox-Chateau places people at the center of his vision. With Doctolib, he has leveraged digital innovation to reduce friction in the healthcare journey, strengthen the patient-doctor relationship, and contribute to a more efficient and inclusive healthcare system.

During the COVID-19 pandemic, the platform played a key role in the vaccination campaign and the rapid expansion of telemedicine.

Convinced that healthcare innovation must be collective, he regularly highlights the importance of working closely with practitioners. Doctors actively contribute to improving Doctolib’s services and developing new features. “Health is something you build together,” he often reminds us.

Commitment and recognition

In 2022, Stanislas Niox-Chateau and his wife created Okola, an endowment fund dedicated to children’s well-being. Their goal: to reduce social inequality, improve access to education, and promote equal opportunities from an early age.

Recognized for his impact and vision, he has been named among the MIT Technology Review’s Innovators Under 35 and appears in several rankings of the most influential figures in French Tech.

A journey shaped by resilience, leadership driven by collective values, and a strong belief that technology should empower people, Stanislas Niox-Chateau embodies a new generation of entrepreneurs committed to positive, human-centered innovation.
