What Plein Sud Groupe does
Plein Sud Groupe is a privately held French technology services group headquartered in Bègles (Nouvelle-Aquitaine), founded in 2001 by Christophe Barrau and Arnold Guibbal as an SFR-branded telecommunications reseller. Over 25 years the company has evolved into a multi-service ESN/MSP operating across six integrated lines: Communications & Collaboration (VoIP, SIP, Microsoft Teams Phone, 3CX), Digital Workspace (Microsoft 365, Adobe Creative Suite), Connectivity & Networks (Cisco Meraki SD-WAN, LAN/WIFI, fiber, 5G), Systems Management (MCO, vDSI virtual CIO, IaaS, backup/PRA), Cybersecurity (Stormshield firewalls, Microsoft Defender/Intune, Entra ID, Thales FIDO, in-house SOC/CSIRT, MCS/RSSI governance), and Artificial Intelligence (Copilot for Microsoft 365, Azure AI Foundry, Adobe Firefly, with structured governance and acculturation programs).
The group serves more than 4,000 clients — primarily French PME and ETI in south-west France and the Lyon region, with additional exposure to healthcare and the associations/social sector — and operates four regional agencies in Bègles, Toulouse (Montrabé), Agen, and Lyon. Its GTM is sales-led and consultative, combining direct field sales with channel distribution through SFR Business (ranked 6th nationally) and a shareholding in the RTEAM national network for multi-site deployment coverage. Revenue is generated through a mix of managed services contracts, software and communication solution resale (Microsoft 365, Adobe, Cisco Meraki, SFR Business connectivity), and certified training engagements. As of end-2025 the company employs roughly 80 collaborators and reports approximately 19M€ in annual revenue, with growth achieved through both organic expansion and a documented M&A track record (INSITU 2011, RTEAM 2016, AOLIA TELECOM 2017, VDI Telecom JV 2023). Arnold Guibbal serves as President of both Plein Sud Communication and Plein Sud IT.

Plein Sud Groupe competitors and assessment
Company assessmentDirect peers
- Hub One: French IT and telecom operator specializing in managed services for enterprise and public-sector clients, with strong airport/transport vertical expertise. Comparable in offering connectivity, managed networks, cybersecurity and unified communications to mid-market and large enterprise.
- SPIE ICS: IT and digital services arm of SPIE Group, providing managed IT, cloud, cybersecurity, and workplace services to French mid-market and enterprise clients. Closely comparable business model — local delivery combined with national roll-out capabilities — and similar vendor ecosystem.
- NXO: French managed IT and telecommunications services provider with similar profile: multi-site enterprise clients, convergence of telecom and IT, and a footprint spanning multiple French regions. Closely comparable in service mix (connectivity, managed IT, cybersecurity, collaboration) and target customer (PME/ETI).
Broad incumbents
- Capgemini: Global French-headquartered IT services and consulting leader with a substantial mid-market and SME-facing practice. Overlaps with Plein Sud on managed services, cloud transformation, and cybersecurity, but at vastly greater scale and with a more consulting-driven model.
- Devoteam: French-founded digital transformation and IT consulting firm with strong cloud and cybersecurity practices (notably Microsoft and AWS). Comparable technology stack and target segments (mid-market and enterprise), though materially larger and more consulting-led than Plein Sud.
- Sopra Steria: Major French-listed IT services group with strong European public-sector and enterprise footprint, including managed services and cybersecurity. Comparable in providing end-to-end IT services to mid-sized accounts, but operating at multi-billion-euro scale versus Plein Sud's 19M€.
- Bouygues Telecom Entreprises: Enterprise arm of Bouygues Telecom offering mobile, fixed, cloud, and managed services to French businesses. Directly comparable as an integrated telecom and IT services provider for the SME/mid-market segment and a key competitor to Plein Sud's SFR Business channel portfolio.
- Orange Business Services: Enterprise division of Orange, providing connectivity, unified communications, cloud, and cybersecurity to French and international enterprise. Overlaps heavily with Plein Sud's portfolio and competes in the same PME/ETI segment, but with national operator scale and direct sales force.
- Econocom: Larger French-headquartered IT services and technology financing group operating across Europe. Comparable as a managed IT, workspace, and cybersecurity services provider for SMEs and large accounts, but at materially greater scale and broader geographic reach.
Others
- SFR Business: Plein Sud's flagship channel partner since 2001, SFR Business is also a broader market incumbent that sells directly to French enterprises via its own sales force and other partners. Acts as both supplier (resell relationship) and indirect competitor in the same SME/ETI accounts.
