Xavier Niel’s biography

Xavier Niel, born on August 25, 1967, in Maisons-Alfort, France, is a prominent French entrepreneur and businessman renowned for his significant contributions to the telecommunications and technology sectors. From a young age, Niel exhibited a profound interest in technology, acquiring his first computer, a Sinclair ZX81, at the age of 15, which sparked his passion for programming.

In the early 1980s, while still in high school, Niel ventured into the emerging field of online services by developing applications for the Minitel, France's precursor to the internet. By 1987, he had founded his first company, specializing in Minitel services, which achieved considerable success and established him as a young millionaire by the age of 24.

In 1991, Niel founded Iliad, a telecommunications company that would become the parent company of Free, one of France's leading internet service providers and mobile operators. Under his leadership, Iliad introduced innovative services, including the launch of Free in 1999, which disrupted the French internet market by offering affordable and high-quality broadband services.

Beyond telecommunications, Niel has diversified his investments across various sectors. He co-owns the French newspaper Le Monde and has stakes in international telecom operators, including Monaco Telecom and Salt Mobile (formerly Orange Switzerland).
