Things we've put our energy into
We manage around EUR 200 million of assets across 80+ ventures, built through different routes. Some we invest in directly, taking a minority stake and working alongside the founders. Some we access through the VC funds we invest in, giving us exposure to a broader portfolio of companies. And some we build ourselves within Fortum, starting from opportunities we identify in our focus areas.
The mix is deliberate. Direct investments let us work closely with individual startups. VC fund investments extend our reach into new networks, technologies, markets and companies beyond our direct portfolio. Venture building lets us pursue opportunities where Fortum has the expertise and capabilities to build something new. What they share is the ground they cover: future energy systems, intelligent operations, and industrial decarbonisation.
