What Open Technology Services does

Open Technology Services (OTS) is a privately held Greek software company, founded in 1993 and headquartered in Thessaloniki, that builds enterprise information systems and digital solutions primarily for Greek public-sector organizations. Its core offering is the Open1 platform — a modular suite spanning financial management (Open1|Finance), payroll and personnel (Open1|HRMS), document and process automation (Open1|Process), project tracking (Open1|Project360), and dozens of vertical applications covering municipal police, cemeteries, property taxes, elections, school requests, waste management, water-utility billing, procurement, and student transport. Standalone products include the ParkaLot smart-parking solution and Cloud Services & Cybersecurity. The platform is delivered via direct sales to municipalities, regions, decentralized administrations, public-law legal entities, municipal water and sewerage companies (DEYAs), universities, and hospitals, supported by an event-driven go-to-market built around the annual OTS Forum and a series of regional OTS Roadshows held across six Greek cities each year.

OTS operates from offices in Thessaloniki (headquarters), Athens, and Trikala, employs 101–250 people, and generates revenue through software licenses/subscriptions, professional services for implementation and support, and training/event fees. Pricing is not publicly disclosed because the Greek public-procurement context drives bespoke, RFP-driven contracting. The customer roster — visible on the company website — includes the Hellenic Fiscal Council, the Region of Central Greece, the Municipality of Oreokastro, the Port Authority, the Aviation Authority, the Municipal Water and Sewerage Companies of Serres and Lagada, the University of Peloponnese, and the Green Fund, among others, indicating deep penetration across Greek local-government and public-utility segments. OTS holds GDPR-compliance commitments and Great Place to Work Hellas certifications (2025 SMB Europe, 2026 Tech and Workplace).

In February 2026, Real Consulting announced an agreement to acquire 100% of OTS for approximately EUR 47 million via a share-exchange mechanism (BDO appraised value), creating a combined entity projected to generate over EUR 67 million in FY2025 revenue and EUR 14 million in EBITDA, with stated growth of over 25% for 2026. The acquisition positions OTS within a larger Greek IT services group alongside strategic institutional investors including Intracom, Motor Oil, Blue Oak, and Red Arrow Holdings, with One Dealer Holdings (controlled by Nikolaos Vardinogiannis) as the majority shareholder of the acquirer.

Direct peers

• Real Consulting: Greek IT consulting and software firm that announced the acquisition of 100% of OTS in February 2026 for approximately EUR 47 million. Both serve Greek public sector organizations with ERP, digital transformation, and IT services, making it the most directly comparable peer and now OTS's parent entity.
• SingularLogic: Leading Greek enterprise software vendor providing ERP, business intelligence, and public-sector solutions to Greek municipalities and enterprises. Directly competes with OTS for Greek public-sector ERP and digital transformation deals.
• Cosmos Business Systems: Greek IT services and software integrator serving public administration, healthcare, and enterprise clients. Overlaps with OTS in providing IT solutions to Greek municipalities and government agencies.
• BGM Associates: Greek IT consultancy focused on public-sector digital transformation, including municipalities and government agencies. Comparable in customer base (Greek public sector) and solution type (IT services and software for public administration).

Broad incumbents

• SAP: Global ERP leader whose public-sector offerings (SAP S/4HANA for public sector, SuccessFactors) compete with OTS's Open1|Finance and Open1|HRMS for larger Greek municipal and government tenders, where OTS competes on local domain expertise and price.
• Microsoft Dynamics 365: Global ERP and CRM platform with growing footprint in Greek public sector and municipal deployments. Competes with OTS in finance, HR, procurement, and citizen services modules, often through local implementation partners.
• Oracle: Global enterprise software vendor with public-sector ERP and cloud offerings. Competes with OTS at the higher end of Greek public-sector procurements where larger municipalities seek enterprise-grade, internationally supported solutions.
• Tyler Technologies: U.S.-based specialist in software for the public sector, including municipalities, courts, and schools. While U.S.-focused, its end-to-end municipal platform mirrors OTS's Open1 strategy and could enter European markets as a competitive threat.
• Infor: Global ERP vendor with industry-specific cloud suites, including public-sector and municipal capabilities. Competes with OTS for mid-market Greek public-sector ERP deployments where customers seek internationally backed solutions.

Regional players

• Civica: UK-based software and services provider dedicated to the public sector, with solutions spanning local government, health, and education. Comparable in vertical focus (public-sector-only software) and could expand into Greek markets via EU channels.
