Tech Nation has unveiled the 25 innovative ClimateTech companies joining its 2026 Climate Programme.

Tech Nation, powered by Founder’s Forum Group – described as the UK’s leading growth platform and industry body for startups and their teams – selected high-potential companies tackling some of the most urgent challenges across food systems, industrial decarbonisation, energy, materials and nature restoration.

Collectively, the cohort has raised $250m+ in funding; works with global corporates including Microsoft, Shell, Salesforce, Heathrow, SUEZ and TotalEnergies; and represents a new generation of founders building commercially viable, scalable solutions to the climate and biodiversity crises.

The four-month growth programme accelerates high-potential tech startups that bridge the gap between climate innovation and industry. The programme supports leading ClimateTech companies to scale their impact by accessing the right investors and multinational customers, and by providing founders with a platform to advance climate policy and remove regulatory barriers.
