Connecting climate innovation
with the capital to scale it

Climate founders need investors who understand their technology, their market and their impact. Climate investors need a reliable flow of relevant, investment-ready startups - and a way to find the ones that are the best match for their investment focus.

Climate Marketplace brings them together in one dedicated climate investment network, connecting founders and investors from around the world so they can find their best matches, connect directly and move faster.

The platform was originally built by a leading European climate accelerator in partnership with a UK university. Since 2020, Climate Marketplace has helped climate startups raise more than €200m.

Acquired and relaunched in 2024, Climate Marketplace is now growing into a global meeting point for climate founders and investors - connecting the people, ideas and capital needed to accelerate the transition.

Leadership

Marianne Lehnis, CEO

Climate Marketplace is led by Marianne Lehnis, who acquired the platform in 2024. A former journalist and Forbes climate tech contributor, Marianne is also the founder and editor of The Green Techpreneur, a media and community platform for climate founders.

Every startup listing is reviewed before it goes live, and every investor account is screened before joining, ensuring quality and relevance on both sides of the marketplace.

Climate Marketplace and The Green Techpreneur are part of a wider ecosystem connecting climate founders, investors and the people driving the transition.
