Professional Service Partners

What Professional Service Partners does

Professional Service Partners (PSP), legally P.S.P. Professional Service Partners A.E., is a privately held Greek systems integrator and managed services provider founded in 2005 and headquartered in Nea Chalkidona, Athens. The company combines resale, integration, and operations across networking (LAN/WAN, switching, routing, wireless), security (firewalls, VPN, remote access), IP telephony and unified communications (Asterisk/Sangoma, Cisco UCM, Yeastar, with multiple endpoint vendors), and structured cabling (copper and fiber optic). It runs a managed IT support practice delivered through three tiers — Gold (24x7 managed support contract with SLAs), Silver (pre-purchased hours or frame agreement), and Pay-as-you-go (per-incident) — sold via direct enterprise field sales and supported by an internal call center.

PSP operates two distinct segments: enterprise managed IT/networking services for SMEs and corporates across multiple verticals (retail, energy, automotive, aviation services, education, hospitality), and dedicated telecommunications-provider services covering central infrastructure, FTTH rollouts, urban node maintenance, and subscriber installations under SLA. Its proprietary differentiator is an in-house Field Service Management software platform that records work orders, tracks technician availability and material dispatch, integrates with Google Maps for real-time routing and ETA, exchanges data with CRM and helpdesk systems, and monitors SLAs — used internally and exposed as a productized offering.

The company employs roughly 65-100+ staff across commercial/administrative, technical direction (engineers, network technicians, back-office agents, dispatchers), and call-center functions, holds Cisco, Asterisk/Sangoma, Fortinet, Panduit and other vendor certifications, and is certified to ISO 9001:2015 and ISO 45001:2018. Notable enterprise clients include Jumbo (multi-country retail), BB Energy (multi-country energy), Saracakis, Carglass, Goldair Handling, Leroy Merlin, University of Western Attica, Grace Hotel, and Stanton Chase Athens. PSP is led by Grigoris Galonakis (CEO, with the company since 2004) and Spyros Bakogiannis (CFO since 2015), operating without external funding rounds, M&A, or parent-company ownership disclosed in the data.
