We are the best-equipped testing lab in CEE, supporting the best producers of automotive or aerospace components in their development, accredited tests, special test equipment or demanding parts production.

Since 1993

Our company was founded in 1993 and originally operated under the SWELL brand. In 2016, it was taken over by the multinational group Altran and later by its new parent company Capgemini.


During this period, our Czech management gained additional experience with complex international projects and, in addition to our company, also managed other entities in Austria, Germany, or Slovakia.


Thanks to this cooperation, we have also expanded our professional expertise - for example, in the production of top equipment for tests in the field of passive safety of cars or in the field of airbag testing. After the management buy-out of our company supported by BHS investment fund, completed in September 2023, we continue to operate as an independent Czech company, thus returning to our roots, under the new brand Tiyo.
