Funding and competition

  • 1grant expected (official)
  • €4MEU contribution per project
  • €4.9Mmedian EU grant of the most similar funded projects
  • 58projects funded in earlier topics of this programme line

Success rates vary widely between topics (often from below 5% to above 30%). Ask us for the success-rate history of this topic before you commit to a proposal.
