Teemu Seppälä is building Finland’s bridge between defence and the technology world.
As the leader of Defence Innovation Network Finland (DEFINE), he drives a nationwide ecosystem bringing together startups, deep tech, investors, industry and defence stakeholders to accelerate the development of next-generation defence and dual-use capabilities.
DEFINE is a crucial part of Finland’s defence innovation architecture and a key platform for NATO Innovation Range activities in Finland — connecting emerging technologies with testing, experimentation and real operational needs.
With a background spanning technology, investment, entrepreneurship and the public sector, Teemu focuses on one thing: turning innovation into defence capability — faster.
