Tecnun promoted the creation of Ceit in 1982. Both entities share the facilities at the University of Navarra's San Sebastián Campus and maintain a close collaboration. Ceit offers Tecnun engineering and PhD students an environment in which they carry out world-class applied research. On the other hand, Tecnun represents a unique opportunity for Ceit to meet the best qualified young engineers.

Ceit is member of Innobasque (Basque Agency for Innovation). It is a private association with strong public support. It was created to coordinate and stimulate innovation in the Basque Country, and to encourage entrepreneurial spirit and creativity.

Ceit and Fomento de San Sebastián, a municipal company dedicated to the promotion and economic and social development of the city, collaborate in projects and activities linked to innovation and the generation of knowledge. The cooperation of both entities has generated the creation of the Bonos Tecnológicos program, the hiring of young researchers and the joint implementation of technological and social projects.

Biodonostia, a national and international reference center in health research, based in Donostia-San Sebastián, maximizes translational research. Commitment to innovation in medical and health technologies reverts in an improvement of healthcare. At the same time, the center generates wealth for the country as inventions turn into products. Ceit collaborates with Biodonostia and “Hospital Universitario Donostia” through Biomedical Engineering projects developed as a package.

Concytec is the institution that governs SINACYT, Peru's National System for Science, Technology and Technological Innovation, and it comprises universities, state research institutions, businesses, associations, and civil society. Ceit is an authorized non-domiciled Center for Scientific Research and Technological Development under Law no. 30309 (Schedule no. 2), in the discipline of Materials Engineering, the sub-area of Materials Engineering and the area of Engineering and Technologies.
