In 1961 Tecnun (School of Engineering, University of Navarra) opens its doors in Donostia-San Sebastián, making it the fourth oldest engineering school in Spain. From its first day, Tecnun combines teaching with research on Metallurgy, a field that is closely tied to the industrial tradition of the province of Gipuzkoa.
In 1963 the CIT (Centro de Investigaciones Técnicas) research centre is created with the funding and support of Caja de Ahorros Provincial de Guipúzcoa (now Kutxabank) and with the mission to carry out projects and provide services for companies.
In 1967, with an eye on the future, Tecnun builds three buildings to house research labs and begins R&D activity in Mechanical, Electronic and Environmental Engineering.
In 1982 CEIT (Centro de Estudios e Investigaciones Técnicas de Gipuzkoa) is born as a non-profit research centre. Though CEIT-IK4 is legally independent from Tecnun, the two institutions maintain close ties, sharing projects and personnel. CEIT-IK4 is immediately designated by the Basque Government as a publically supported centre and it is declared a public utility.
In 1990 CEIT employs 104 people.
In 1991 CEIT begins conducting research in Microsystems.
In 1996 CEIT's first spin-off, ATM, is launched.
In 1997 research in Communications begins.
In 2000 CEIT employs 176 people.
In 2004 CEIT is one of the four founding members of the IK4 Research Alliance, and in 2005 IK4 is constituted as a federation of autonomous technology companies whose members share strategies and combine competences.
In 2006 CEIT-IK4 inaugurates its new building at the Technology Park in Miramon, which houses the research facilities for Electronics, Communication Systems and Microsystems.
In September 2013 CEIT-IK4, Tecnun and Clínica Universidad de Navarra launch the Center for Biomedical Engineering, a research centre where professionals from the fields of engineering, life sciences and business collaborate on R&D projects.
In 2015 CEIT-IK4 employs 245 people, and the thirteen spin-offs that have come into being since 1996 have over 300 high value added employees.
