Founded in 2001, CELESTE is a leading European fiber, cloud and cyber operator and number one pure-play B2B provider operating its own proprietary infrastructure. The group manages more than 13,600 km of local fiber network across France and Switzerland and owns 6 data centers. CELESTE delivers a sovereign and secured offering widely recognized for its quality, and continuously deploys innovative and bespoke solutions dedicated to enterprises under a one-stop-shop model that combines fiber, cloud and cybersecurity services.

InfraVia invested in CELESTE in 2019. Since then, it has worked alongside management to accelerate CELESTE’s transformation from a local operator into a unique one-stop-shop B2B solutions provider including connectivity, telecom, cloud, and cybersecurity solutions. During this period, CELESTE executed an ambitious consolidation strategy, with multiple strategic acquisitions including Pacwan, Option Service Télécom, Via numérica, Ariane, Stella Telecom, BLHD, Oceanet Technology, Everko, and Magic Online, as well as VTX in Switzerland, significantly strengthening its network footprint, service capabilities and market positioning. Celeste has developed a product offering that meets the need of a large and diversified portfolio of blue-chip customers, with a business model set for future growth and market consolidation.

Nicolas Aube, CEO, CELESTE said, “We look forward to the next chapter of our growth journey. Today, CELESTE is strongly positioned to pursue its expansion, accelerate market consolidation and continue to deliver secured, resilient and high-performance digital infrastructure services to our clients. I would like to warmly thank InfraVia for their trust and support since 2019, which has been instrumental in our transformation and growth.”

Gabriel Gauthier, Partner at InfraVia Capital Partners added: “It has been a pleasure working with Nicolas Aubé and CELESTE teams over the past years. The work that has been achieved to build a unique B2B one-stop-shop positioning for the company leaves CELESTE well poised for the next development cycle.”

The transaction will require the completion of the information and consultation process with the relevant French employee representative bodies and remains subject to the satisfaction of customary conditions precedent. Completion is expected in Q1 2026.
