No. Any type of organisation can be part of a Eurostars project consortium, although the main partner must be an R&D – performing SME. To qualify as an R&D-performing SME an organisation must first comply with the EC definition of an SME. In addition, it must also meet the thresholds for dedicated R&D FTEs or turnover set by EUREKA.
This and all other eligibility criteria are described in detail in the Guidelines for Eligibility.
