Slush 2025 made one thing unmistakably clear. Sustainability is no longer a side topic. It is the engine of a new wave of entrepreneurial innovation. In this special episode recorded live at Slush in Helsinki, Michael Hanf speaks with founders who are reshaping the future of energy, food, finance, and behavioural change.

From wave energy devices designed for real world conditions, to next generation small wind turbines, to platforms that accelerate financing, planning, and grid integration, this episode explores the systems that are finally removing friction from the sustainability transition. We also look at how precision fermentation could rewrite the economics of protein production and how gamification can make sustainable behavior easier and more rewarding for young people.

Guests include founders from Geco, Amertate Energy, Dowgo, Coeus AI, Synergi, Verley, and WasteSide. Together, their pitches reveal a transition that is speeding up and expanding in scope. The ideas presented at Slush show that the future of sustainability will be driven by simplicity, data, coordination, and a far more diverse mix of solutions than ever before.

If you want a clear snapshot of where sustainable innovation is heading in 2025, this episode is a sharp and honest tour through the technologies and systems that matter most.
