ZEPREN obtains the “Innovative SME” seal

Today, ZEPREN Solutions has been awarded with the “Innovative SME seal” (Sello PYME Innovadora) by the Spanish Ministry of Science and Innovation.

The Innovative SME seal is a recognition granted by the Ministry of Science and Innovation to companies whose activity focuses on Research, Development and Innovation. The distinction was created in June 2014, with the aim of establishing a system of positive discrimination among companies that favours those most likely to remain in time, grow and be competitive.

This certificate, valid for the next 3 years, will ease the access to R&D funding and tax incentives, and will support our efforts to continue developing innovative products and solutions for our customers.
