Stella Telecom competitors and assessment
Company assessmentBroad incumbents
- Orange Business: B2B services division of Orange, the incumbent French carrier. Comparable as the dominant enterprise connectivity, cloud and security provider in France, competing with Celeste on national multi-site fiber, hybrid cloud and managed network deals.
- Free Pro: Enterprise brand of Iliad/Free in France, selling fiber, mobile and hosted services to businesses. Comparable as a price-aggressive French enterprise telecom operator competing for the same SME and mid-market accounts as Celeste.
- Equinix: Global colocation and interconnection operator with datacenters in France. Comparable to Celeste's colocation and Cloud Direct Access services as a broader, deeper-pocketed incumbent that French enterprises also use for hybrid cloud connectivity.
- SFR Business: B2B subsidiary of Altice France offering fiber, mobile, cloud and cybersecurity to French enterprises. Overlaps Celeste's full product portfolio and customer segments at national scale.
- Bouygues Telecom Entreprises: Enterprise arm of Bouygues Telecom, one of France's four national telecom operators. Directly comparable because it sells dedicated fiber, mobile, cloud and managed services to French businesses across all segments — including the same mid-market accounts Celeste targets.
Regional players
- Colt Technology Services: European B2B provider of dedicated fiber, wavelength, SD-WAN and managed services with a strong French and pan-European enterprise footprint. Comparable to Celeste on dedicated fiber and lambda services to multi-site enterprises, though operating at larger scale and broader geography.
Direct peers
- Sewan: French B2B cloud and telecom operator providing hosted PBX, SIP trunk, fiber, mobile and cloud services to SMEs and mid-market customers. Closely comparable to Celeste on customer profile and bundled cloud/telephony/connectivity offering, without national incumbent scale.
- OVHcloud: European cloud and hosting provider with its own datacenters and fiber infrastructure, serving SMEs, public sector and enterprise customers. Comparable to Celeste in the cloud/hosting and integrated infrastructure segments, particularly for customers seeking a non-US hyperscaler alternative.
- Hexatel: French enterprise telecom operator providing fiber, mobile, cloud and hosted telephony to businesses. Closely comparable as a mid-sized alternative operator targeting the same SME-to-mid-market segment with bundled services.
- Oceanet Technology: French managed service provider offering cloud hosting, fiber connectivity, cybersecurity and telephony to SMEs and mid-market accounts. Highly comparable to Celeste as a similarly sized B2B operator built around integrated managed services rather than pure connectivity.
