Eurofiber and Antin Infrastructure Partners: a decade-long winning partnership
"This year marks two important milestones: Eurofiber’s 25th anniversary and our 10th year of partnership with Antin,” says Alex Goldblum, CEO of Eurofiber. “In the ten years since Antin Infrastructure Partners acquired Eurofiber, our company has evolved from a scale-up mainly in the Netherlands to become the leading European provider of open access digital infrastructure. Together, we have expanded our horizons, embraced innovation, and consistently delivered exceptional value to our customers. We are proud of the journey we embarked upon together and are in equal measure excited about the future; a future in which secure digital infrastructure will only increase in importance.”
When Antin Infrastructure Partners acquired Eurofiber as part of its Flagship Fund II, the company operated mainly in the Netherlands, had revenues of about €130 million, a fiber-optic network of 18,000 km and about 3,000 customers. Over the past 10 years, with Antin’s support, Eurofiber has more than doubled its revenues to over 300 million euros at end-2024, operates in 4 countries, has grown its fiber optic network four-fold to more than 76,000 kilometers and tripled its customer base to about 9,000 customers. In the Netherlands, Eurofiber has become the leading B2B connectivity provider.
“We were attracted from the start by Eurofiber’s stellar track-record, talented management team and strong growth potential, as well as by the fact that they viewed their business with an infrastructure mindset,” says Stéphane Ifker, Managing Partner of Antin Infrastructure Partners. “We shared their vision of expanding the company's presence into multiple markets, anticipating the increasing demand for open access networks and the expected internationalization of the industry, and we’re very pleased to see that one decade on, this ambition has clearly been realized.”
Eurofiber quickly got down to business after Antin’s entry, combining both organic growth and acquisitions, with more than €1.5 billion of capital expenditure deployed into the Eurofiber network to grow it by some 58,000 kilometers. Expansion started with the acquisition of B-Telecom in 2015, adding 7,500km network and nationwide coverage in Belgium. A year later, Eurofiber acquired Dataplace to complement dark and lit connectivity offering with regional edge co-location. Today, the Eurofiber Cloud Infra business unit comprises of 11 sites with a total capacity of 24MW across the Netherlands and France, providing (hybrid) cloud infrastructure services including liquid cooling and high-performance computing (HPC) capabilities in select sites.
In 2019, Eurofiber and Antin crossed new borders again with the acquisition of three companies in Northern France, Eurafibre, Eura DC and ATE, laying the foundations for the creation of a nationwide platform targeting 25 metro areas by the end of 2025. At the same time, a dedicated International Business Unit was established to serve global carriers and hyperscalers, addressing their cross-border connectivity needs.
In 2020, joint ventures in Belgium (Unifiber, with Proximus) and Berlin (Eurofiber Netz, initially Vattenfall-Eurofiber) led to the successful deployment of wholesale Fibre-to-the-Home networks. These initiatives have created a footprint of approximately 360,000 homes passed to date, with more than 15 ISPs, including Proximus, 1&1, Telefónica, Pÿur, and Vodafone. The overall future target is to reach around 1.1 million homes passed.
Also in 2020, Eurofiber welcomed Dutch pension investor PGGM alongside Antin, which renewed its commitment as majority shareholder.
In 2021, Eurofiber further expanded its presence in Germany through a partnership with NGN, adding another 19,000 km to its pan-European network.
“The strength of our partnership lies in our shared vision of the vital role that open access digital infrastructure plays in the economy and society,” says Alex Goldblum.
Additionally, Eurofiber has established itself as a leader in sustainability, achieving a Platinum EcoVadis rating in 2024, which places it in the top 1% of all companies assessed globally. Eurofiber has also made a public commitment to long-term decarbonization by formalizing a science-based target, approved by the Science Based Targets Initiative (SBTi), to achieve net zero emissions across all scopes by 2040.
Recognizing the vital importance of quantum secure networks for the resilience of our digital society, Eurofiber has been at the forefront of innovation, designing and building quantum communication links and proposing Quantum Key Distribution (QKD) networks. This commitment to innovation has resulted in operational quantum networks in locations such as the Port of Rotterdam. Eurofiber's innovation capabilities have been acknowledged through several prestigious awards, including IT Infrastructure Innovator of the Year 2022 (Data News, Belgium), Networking & Edge Innovator of the Year 2025 (Dutch IT Channel), and runner-up CyberSec Europe Award 2025.
“Innovation and sustainability are ingrained into how Eurofiber runs its business,” says Antin Senior Partner Simon Soder. “Eurofiber’s infrastructure is a critical enabler for its customers when it comes to adoption of technologies such as AI and quantum computing, and at the same time fiber is also a more energy-efficient form of connectivity than the alternatives.”
