The company was founded in September 2001 by a team of

computer scientists and engineers from the University of

Crete in Greece, and Critical Publics, a U.S. based group

specializing in the application of new technologies to the

communications needs of corporations and public

organizations.

Virtual Trip is located at the Science & Technology Park of

Crete, at the city of Heraklion, from where it provides a range

of services in the fields of systems consulting, design and

back-end software engineering. The company has an

international presence through the operations of the Critical

Publics group in London.

The company aims to provide its services to the global

market, utilizing its considerable expertise in specialized

sectors such as digital security, high performance computing,

Internet systems development, and systems software.

The Virtual Trip model is based on exploiting the cluster of

specialist knowledge and expertise built-up around the

University of Crete and the Foundation of Research &

Technology, Hellas (FORTH) to deliver competitively priced

top end consulting, design and development work globally,

eliminating geographic barriers.

Virtual Trip not only provides its services as a primary

contractor but will also undertake the back-end development

work for projects as a member of consortia and as a

subcontractor.
