The shares were purchased from Apax Partners sas, which acquired Expereo from The Carlyle Group in 2018.
David Nahama, senior partner at Vitruvian Partners, said: "We have been tracking Expereo since 2016 and have seen the company consistently outperform, and more recently make multiple significant strategic acquisitions.
"Expereo has established a global leadership position in the highly attractive global cloud and software-defined networking market, allowing it to deliver compelling and differentiated solutions to its customers, underpinning its attractiveness from an investment perspective. We approached Irwin and Thomas late last year and are delighted to be partnering with the Expereo team and Apax on the next significant chapter of Expereo's expansion and success."
Apax Partners will remain as a minority shareholder alongside Vitruvian and the company's management team, which will continue to lead the business. The completion of the transaction is subject to obtaining customary merger control clearances.
"Vitruvian Partners will further bolster our ambitious growth trajectory, enabling us to capitalise even faster on the fundamental changes and opportunities digital transformation brings in the global network and cloud connectivity space," said Irwin Fouwels (pictured), CEO of Expereo.
"Vitruvian and the continued support of Apax Partners, will enable us to further build out our leadership position at scale whilst broadening our services suite, enabling our global enterprise customers' network transformation and cloud-first strategies with enhanced internet and cloud access services with a single, best-in-class, digital customer experience".
However, commenting on the benefits of the deal, Joe O'Mara, partner at Vitruvian partners, said it could allow Expereo to fund further growth through acquisitions.
He said: "Together with Apax, we believe we have significant capital and operational capabilities to support Expereo's growth and acquisition aspirations."
Expereo works with 30% of the Fortune 500 and also supports enterprise and government sites worldwide with its global internet connectivity, SD-WAN, and cloud acceleration services.
