ESA BIC Castilla y León

Castilla y León has been selected to host one of the first Spanish accelerators of aerospace projects in collaboration with the  European Space Agency  (ESA)

ESA's approval of the Castilla y León site is due to key factors such as:

  • The existence of an aerospace innovation pole, with a consolidated sector that covers a large part of the value chain.
  • The commitment of more than 50 public and private entities, which have shown their support to the ESA BIC Castilla y León initiative.
  • The previous experience of the Instituto para la Competitividad Empresarial de Castilla y León, both in accelerating business projects (first public accelerator in Spain), and in providing funding and services.
  • The specific characteristics of the territory of Castilla y León with favourable aerospace.
