Dr Ari Kristinn Jónsson has just stepped into the newly created role of President of the NATO Innovation Fund (NIF), the €1 billion venture fund backed by 24 NATO countries to invest in technologies that strengthen defence, security, and resilience across the alliance. Pathfounders caught up with him to unpack how he plans to steady the NIF ship after a turbulent period. Correction: In the video, we say Dr Ari Kristinn Jónsson replaced Klaus Hommels at head of NIF. Hommels has Klaus stepped into a new advisory role at the Fund’s Geopolitical and Strategic Advisory Council, focused on providing the NIF with guidance on industrialisation and scaling challenges. Dr Jónsson's role as President is a new one, and he will be reporting to the NIF Board.
