History of ADA

ADA Celebrates more than 35 consecutive years in Software Development

More than 1000 Clients and over 2000 Companies in Cyprus and Abroad entrusted ADA Software for their computerization since 1985. ADA has released in 2021 the NEW VERSION OF SOFTWARE ADA SOFTWARE 12 with extra facilities and even easier to use.

Founded in 1985 as a limited liability company under the name ADA Computer Education Ltd, it was the first Computer Training Institute in Limassol, registered with the Ministry of Education, with subsidized courses from the Cyprus Industrial Training Authority.


ADA provides a complete range of computer software services, including design, development, supply, installation and training. After-sales service, maintenance and upgrading of software are important services for the smooth and uninterrupted operation of any business. ADA also provides consulting services for software and hardware, and various other related services, such as data recovery.

The founder and Managing Director, Athos D. Tillyris, who graduated with honors from the University of Essex, UK, in 1980, is one of the pioneers in Computer Science in Cyprus. He was the founder and first president of the Cyprus Information Technology Companies Association (a member of the Cyprus Chamber of Commerce & Industry) and a Board member of the Limassol Chamber of Commerce & Industry. He has represented Cyprus at many International Conferences and IT exhibitions abroad.

The company developed its own software, initially by specializing in the tourism and shipping sectors as well as ship management, and became a pioneer in the Cyprus market. Shortly it expanded into applications software such as Accounting, Stock Control & Invoicing, Payroll, Fixed Assets and Job Costing, covering the entire spectrum of business applications. In 1997 ADA made its first software installation abroad (Germany).

The company continued to expand and, in 2001, was the first Cypriot software company to develop its own ERP software in Windows, based on the needs of the Cyprus market. ADA developed new software for insurance agents, building contractors, for Members Register, Library and Archive Management, Timesheets and invoicing for Law and Audit firms and various other custom- made applications specializing in specific business needs.

In 2005, ADA became a Microsoft Empower ISV Partner. In 2007, the company signed an agreement with Amadeus (Online Ticketing & Reservations System) to automatically import data into its own travel software (Back Office). The software is offered, at the same time, for SABRE.

In 2006, ADA acquired its own new offices. An area has been set up as a Computer Museum (the only one in Cyprus), where one can see the development of computers since their earliest stages.

As Managing Director Athos Tillyris says, the main reasons for the firm’s success are a love of the profession, honesty and hard work. “The eager, friendly and prompt service, the integrity and parameterization of the software, our dedication to perfection, frequent upgrades, the open architecture of the software design, its compatibility with all versions Windows, together with absolute confidentiality, friendly relationships and the trust of our clients and associates, are the key reasons for our constant presence for more than 35 years. With the same enthusiasm, dedication and zeal, we shall continue to strive towards our 50th anniversary.”
