Plein Sud Groupe

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.

Direct 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.
