Klima

What Klima does

Klima operates a consumer-facing mobile climate action application available on iOS and Android, designed to enable individuals to calculate their personal carbon footprint, fund certified carbon offset projects, learn emission-reduction strategies, and amplify climate impact through social/community features. The product integrates a proprietary carbon footprint calculator described as one of the most precise personal calculators available, a marketplace of offsets restricted to Gold Standard and Verified Carbon Standard certified projects, a personalized reduction guide with the Climate Class video series, and social tracking of collective impact including friends-of-friends metrics. The app was certified as a B-Corp, winner of an Apple Design Award (2021), and featured on Earth Day 2021 by Apple.

The company monetizes through a recurring monthly subscription model targeted primarily at climate-conscious individual consumers. The company operated a direct-to-consumer go-to-market motion, with global app store distribution and earned media presence across Forbes, TechCrunch, Wired, and Fast Company. Following its April 2022 Series A of €10 million led by Keen Venture Partners, Klima announced expansion into B2B corporate offerings focused on employee sustainability engagement in the U.S. and DACH regions. Co-founded by Markus Gilles (CEO), Jonas Brandau (CPO), and Andreas Pursian (CTO), Klima operated from Berlin, Germany as Climate Labs GmbH with 11–50 employees.

In 2024–2025, Klima's strategic posture shifted significantly toward climate-tech investing through Alantra's Klima Energy Transition Fund, leading or participating in investments including GridBeyond (AI energy optimization), maxwell+spark ($15M Series B lead, lithium-ion batteries for industrial logistics), Enmacc (European OTC energy trading platform), and the Solar Monkey/Eturnity merger (European solar installer software). In 2025, Klima was acquired by Wren, another consumer climate action platform, ending its independent operations.
