Crown Defence has appointed Jari Mielonen as its new
Chief Executive Officer.
He brings with him strong international experience in technology leadership and strategic roles in high-tech growth companies.
Mielonen has a deep background in defence and security technologies, including cyber security, and has worked in leadership and board positions in a range of industry organisations.
He has held key roles at the Finnish Information Security Cluster (FISC), the Association of Finnish Defence, Space and Aviation (AFDA), and AmCham Finland. Over the years, he has built trusted partnerships with national defence authorities and stakeholders across Europe.
His network is backed by a European Defence Academy (SERA, Paris) certification.

It is an honour to join a company as innovative and strategically relevant as Crown Defence. I look forward to working closely with the team, clients and partners as we shape the next phase of growth together, says Jari Mielonen.
As Jari Mielonen takes on the CEO role, current CEO Mattipekka Kronqvist will transition to Chairman of the Board.
Our operations are expanding, and we are moving from a development-driven phase to commercial activity while continuing to innovate. The pilot projects launching this autumn are a clear milestone on that path. I’m delighted to welcome Jari to lead the company at this exciting point in our growth journey. His strengths are a perfect match for the task ahead, says Mattipekka Kronqvist.
Crown Defence welcomes Jari to lead the company into its next chapter of growth, innovation, and impact in the defence technology sector.
