Xavier Niel (born 25 August 1967) is a French billionaire businessman, investor, and telecommunications executive. He is the founder and majority shareholder of Iliad, the parent company of the Free brand, which operates as France's second-largest internet service provider and third-largest mobile operator. Over the course of more than three decades, Niel has built a sprawling business empire that extends well beyond telecommunications into media, technology investing, education, and real estate. He is co-owner of the French newspaper Le Monde, owner of Monaco Telecom and Salt Mobile, and serves as a board member of KKR, Unibail-Rodamco-Westfield, and ByteDance. Known for his disruptive approach to business—particularly his strategy of offering low-cost services to challenge established incumbents—Niel has been a defining figure in France's technology and telecommunications landscape since the early 1990s. He is also the founder of École 42, a tuition-free computer programming school with a novel pedagogical model that has drawn international attention. His investments through Kima Ventures have made him one of the most prolific angel investors in the world. As of January 2026, his net worth is estimated at approximately US$14.2 billion.

Early Life

Xavier Niel was born on 25 August 1967 in Maisons-Alfort, a commune in the southeastern suburbs of Paris, France. He displayed an early aptitude for technology and entrepreneurship, reportedly beginning his business ventures at the age of fifteen. As a teenager, Niel immersed himself in the nascent world of computing and telecommunications, gaining practical experience with the French Minitel system—a pre-internet online service widely used in France during the 1980s and early 1990s. His early encounters with Minitel would prove formative, as the platform gave him both technical knowledge and a keen understanding of how to monetize digital services.

Niel's entrepreneurial instincts led him to launch services on the Minitel platform while still a young man, generating revenue and gaining firsthand experience in the business of connecting users to information and communication tools. This early start distinguished him from many of his later peers in the French technology sector, who typically followed more conventional paths through elite educational institutions before entering the business world. Niel's trajectory was more self-directed and unconventional, a characteristic that would come to define both his business strategy and his public persona.

Growing up in the greater Paris area provided Niel with proximity to France's commercial and technological centers. While details about his family background remain limited in public sources, his early entrepreneurial activity suggests a degree of independence and self-motivation that set the stage for his later achievements in the telecommunications industry.

Career

Early Ventures and Minitel

Niel's first significant business activities were rooted in the Minitel ecosystem. During the late 1980s, he operated services on the platform, which at the time served as France's primary electronic information network, predating widespread internet adoption. These early ventures provided Niel with capital and, more importantly, with deep insight into the economics of telecommunications and digital services. His Minitel operations gave him experience in managing subscription-based and usage-based revenue models, skills that would later prove critical in his disruption of France's broadband and mobile markets.

By the early 1990s, Niel had transitioned from Minitel services to internet-related ventures, recognizing the transformative potential of the nascent World Wide Web. He founded Worldnet, one of France's first internet service providers, in 1993. This early entry into the ISP market positioned Niel at the forefront of France's digital revolution.

Iliad and Free

Niel founded Iliad in 1991, initially as a provider of Minitel and directory services. The company evolved alongside the internet, and in 1999 Iliad launched Free, a low-cost internet service provider that would fundamentally reshape the French broadband market. Free's business model centered on offering high-speed internet access at prices significantly below those of incumbent operators such as France Télécom (now Orange) and SFR. The company's flagship product, the Freebox, was one of the first triple play devices in the world, bundling internet, television, and telephone services into a single box offered at a flat monthly rate.

Free grew rapidly to become France's second-largest ISP, and its aggressive pricing strategy forced competitors to lower their own rates, a phenomenon sometimes referred to as the "Free effect" on the French telecommunications market. Niel's approach drew comparisons to disruptive business models in other industries, and he was profiled extensively in international media as an unconventional figure willing to challenge the established order.

In January 2012, Free launched its mobile service, Free Mobile, entering the French wireless market with prices dramatically below those of existing operators. Free Mobile offered unlimited voice and data plans at a fraction of the cost charged by competitors, sending shockwaves through the industry and triggering a wave of price reductions across the sector. The launch was described as one of the most significant events in the history of French telecommunications. Free Mobile quickly attracted millions of subscribers and cemented Iliad's position as a major force in French telecommunications.

Niel serves as chairman and chief strategy officer of Iliad, maintaining his role as the company's majority shareholder and guiding its long-term direction.

International Telecommunications Expansion

Beyond France, Niel has pursued an aggressive strategy of international expansion in the telecommunications sector. In April 2014, he acquired a controlling stake in Monaco Telecom from Cable & Wireless Communications, becoming the dominant telecoms operator in the principality of Monaco.

Niel also acquired Salt Mobile (formerly Orange Communications), the third-largest mobile operator in Switzerland, further extending Iliad's international footprint. Additionally, he purchased Eir, Ireland's incumbent telecommunications provider, in a deal that demonstrated his appetite for entering established European markets and applying his characteristic low-cost strategy.

These international acquisitions reflected Niel's belief that the model proven by Free in France—offering competitive services at disruptive price points—could be replicated in other European markets where incumbents had maintained relatively high prices.

Media and Entertainment

Niel has made significant forays into the media sector. He is a co-owner of Le Monde, one of France's most prestigious daily newspapers. His involvement in the media industry extends to the entertainment sector as well.

In 2025, Niel, through the audiovisual group Mediawan which he co-founded, completed the acquisition of a former military air base near Reims in the Champagne region of France with the intention of building a major film and television studio complex. Dubbed "Les Studios de Reims," the project aims to create one of Europe's largest production facilities. The project has been described in media reports as an effort to establish a "European Hollywood," providing large-scale production infrastructure to compete with studio facilities in the United Kingdom and elsewhere.

Technology Investing

Niel is one of France's most prolific technology investors. Through Kima Ventures, the venture capital firm he founded, Niel has invested in hundreds of startups across a wide range of sectors, from artificial intelligence to fintech to consumer technology. Kima Ventures is known for its high-volume approach, making numerous small investments each year and building one of the largest startup portfolios of any individual investor globally.

In December 2025, Niel, alongside former Google CEO Eric Schmidt, backed Gradium, a Paris-based artificial intelligence voice startup that spun out of a nonprofit research lab and raised $70 million in funding. The investment reflected Niel's continued interest in cutting-edge AI technologies and his role in supporting France's growing AI ecosystem.

Niel also serves on the board of directors of several major international companies, including KKR, the American private equity firm; Unibail-Rodamco-Westfield, the European commercial real estate company; and ByteDance, the Chinese technology conglomerate and parent company of TikTok. These board positions place Niel at the intersection of global finance, real estate, and technology.

Involvement in the Exaion-MARA Deal

In early 2026, French government officials sought to involve Niel in mediating sovereignty concerns related to a deal between MARA Holdings, an American company, and Exaion, a subsidiary of the French state-controlled utility EDF. MARA Holdings held a controlling 64% stake in Exaion, and French officials were reported to have tapped Niel to invest in Exaion as a means of easing concerns about foreign ownership of strategically sensitive digital infrastructure. The episode illustrated the French government's view of Niel as a trusted national figure in the technology and digital infrastructure sectors.

Bid for Le Coq Sportif

In 2025, Niel was part of a consortium, alongside French Olympic judo champion Teddy Riner and the brand management company Iconix, that submitted a takeover bid for Le Coq Sportif, the French sportswear brand. Lawyers for the consortium alleged that their bid had been "deliberately hampered" and "weakened" during the process. The episode highlighted Niel's interest in extending his investment activities beyond technology and telecommunications into the consumer brand sector.

École 42

In 2013, Niel founded École 42, a private, tuition-free computer programming school in Paris. The school operates without traditional teachers, textbooks, or lectures, instead relying on a peer-to-peer learning model and project-based curriculum. Students are selected through an intensive admissions process that does not require prior academic credentials, and the school is open to applicants between the ages of 18 and 30.

Niel reportedly invested approximately €70 million of his personal fortune to establish the school, which was named after the number 42—a reference to The Hitchhiker's Guide to the Galaxy, in which the number 42 is famously presented as "the answer to the ultimate question of life, the universe, and everything." École 42 has since expanded internationally, with campuses in multiple countries, and has been recognized as an innovative model for technology education. The school's approach has been described as particularly significant for its emphasis on accessibility, removing financial barriers that often prevent talented individuals from pursuing careers in software development and technology.

Personal Life

Xavier Niel has been in a relationship with Delphine Arnault since 2010. Arnault is the daughter of Bernard Arnault, chairman and CEO of LVMH, the French luxury goods conglomerate. Together, the couple has children; Niel has a total of four children.

Niel maintains a significant real estate portfolio. In November 2025, he purchased a historic residence near Versailles that was originally built for a royal mistress of King Louis XV. The property was acquired for approximately $45 million, adding to Niel's growing collection of notable properties.

Niel has been described in the Financial Times and other publications as one of France's most unconventional and influential business figures. Despite his considerable wealth, he has cultivated a reputation for a relatively understated public persona compared to some of his peers among France's business elite, though his high-profile relationship with Delphine Arnault and his involvement in major media properties ensure that he remains a prominent figure in French public life.

Recognition

Niel's impact on French telecommunications has been the subject of extensive coverage in international media, including profiles in The New York Times, The Economist, The Guardian, the Financial Times, and Forbes. The New York Times described him as a "billionaire who breaks the mold," emphasizing his unconventional path to success and his willingness to challenge entrenched business interests. The Economist profiled his combative stance toward large technology companies, noting his willingness to confront industry giants such as Google.

Forbes has consistently included Niel on its list of the world's billionaires, estimating his wealth at approximately US$14.2 billion as of January 2026. The French business magazine Challenges has similarly tracked his wealth and ranked him among France's wealthiest individuals.

École 42, his tuition-free coding school, has received widespread attention as an innovative educational model, with coverage in outlets such as VentureBeat and the Financial Times.

Legacy

Xavier Niel's influence on the French and European telecommunications industries is substantial and well-documented. The launch of Free's low-cost broadband and mobile services fundamentally altered the competitive dynamics of the French market, driving down prices for consumers and forcing established operators to adapt their business models. The so-called "Free effect" has been credited with making broadband and mobile services more affordable for millions of French households.

Beyond telecommunications, Niel's creation of École 42 represented a challenge to conventional models of higher education, demonstrating that technology training could be delivered effectively without traditional institutional structures, tuition fees, or academic prerequisites. The school's peer-to-peer model has inspired similar initiatives in other countries and contributed to broader conversations about the future of education in the digital age.

Through Kima Ventures and his personal investments, Niel has played a significant role in nurturing France's startup ecosystem. His willingness to make large numbers of early-stage investments has provided capital and credibility to French entrepreneurs at a time when the country's startup scene was still developing relative to those in the United States and the United Kingdom. His board positions at major international companies, including KKR and ByteDance, have further cemented his status as one of the most connected and influential figures in global technology and finance.

Niel's expansion into media—through his co-ownership of Le Monde and his studio-building ambitions through Mediawan—reflects a diversified approach to business that encompasses traditional media, digital infrastructure, and content production. His 2025 acquisition of a former air base to build Les Studios de Reims signals an ambition to reshape France's position in the European entertainment industry, creating production infrastructure that could attract international film and television projects to the country.

His involvement in matters of national interest, such as the Exaion-MARA sovereignty negotiations in 2026, underscores the extent to which Niel is viewed by French authorities as a figure of strategic importance in the country's digital and industrial policy.
