Kim Jäämeri, former Commander of the Finnish Air Force and Lieutenant General (retd.), has been appointed Defence & Security senior advisor at the technology company Reaktor. In his new role, Jäämeri supports Reaktor's goal of expanding its technology solutions and software business into global defence markets.
"Kim is one of Finland's most experienced defence professionals, and he has spent his entire career leading in complex operating environments that demand decisions. It's great to have his expertise now supporting Reaktor's development in defence and security", says Pekka Horo, CEO of Reaktor.
Jäämeri served as Commander of the Finnish Air Force from 2014 to 2017, as Chief of Strategy of the Finnish Defence Forces from 2017 to 2022, and as Finland's first Military Representative to NATO and the EU from 2023 to 2025. He is chair of the board of Belvictor Oy, a board member of In Parallel Oy, a member of the Royal Swedish Academy of War Sciences, and an advisor to several Finnish and international companies.
"I know Reaktor as a trusted frontrunner from my years in the Finnish Defence Forces. Building digital capabilities is now inseparable from strengthening every area of defence. Reaktor's track record and expertise are an excellent foundation for growing the Defence & Security business, and for contributing to the security of our allies and partners as well. Given my background, joining Reaktor is a natural way to continue the work of improving our shared security", Jäämeri says.
In Europe, digital sovereignty carries particular weight in defence right now. NATO and its member states are going through a rapid, multi-year digital transformation to reinforce their technological edge. Reaktor's Intelligence Software Suite, built for defence and security organisations, combines data-driven decision support, controlled information sharing across systems at different classification levels, and a secure AI platform to create competitive advantage for all users from the battlefield of today to the operating environments of the tomorrow.
"Finland stands out in how it meets the security threats of our time. Strengthening our own defence is best continued in cooperation with like-minded countries, where a strong reputation opens new opportunities for companies and for the Defence Forces alike", Jäämeri says.
