💰 Funding

NGI Open Calls (EU)

  • Funding is allocated to projects using short research cycles targeting the most promising ideas. Each of the selected projects pursues its own objectives, while the NGI RIAs provide the program logic and vision, technical support, coaching and mentoring, to ensure that projects contribute towards a significant advancement of research and innovation in the NGI initiative.
  • The focus is on advanced concepts and technologies that link to relevant use cases, and that can have an impact on the market and society overall. Applications and services that innovate without a research component are not covered by this model.
  • Closing Date: 1 February 2022, 12:00 PM CET
  • Varying amounts of funding.
