Another key player is **Atomico**, the VC founded by Skype’s Niklas Zennström, which actively seeks climate tech opportunities within its broader deep-tech portfolio, having invested in **Northvolt** (battery manufacturing) and **Climeworks** (direct air capture). **Balderton Capital**, a leading European VC with London headquarters, has a strong focus on sustainability and has invested in **Lime** (e-scooters) and **Grover** (circular consumer electronics). **DN Capital**, with offices in London, invests in climate-positive solutions through its **DN Climate Tech Fund**, targeting software and hardware innovations in energy efficiency, carbon accounting, and clean mobility. The **London Co-Investment Fund**, managed by **Crowdcube** and backed by the Mayor of London, specifically supports early-stage climate tech startups in the capital, often co-investing with angel networks. **IQ Capital** has a climate tech vertical within its deep tech focus, funding companies like **Cambridge GaN Devices** (energy-efficient semiconductors) and **Spectral Compute** (low-power computing). **Octopus Ventures**, a major London VC, has a dedicated “Generation Impact” strategy that invests in transformative climate and health startups, with notable bets on **Hive** (smart home energy) and **Vertical Aerospace**. **Seedcamp**, a London-based early-stage fund, has a sustainability track and has backed **Drover** (electric car subscription) and **Yunlu** (solar energy). Additionally, **Axis Innovation** and **Green Angel Ventures** (part of the UK’s Green Angel Syndicate) are active in London, providing seed-stage capital and mentoring for climate tech founders. For later-stage growth, **BGF** (Business Growth Fund) has a climate tech fund that invests in scaling UK companies like **Oxbotica** (autonomous electric vehicles) and **Bulk** (renewable energy procurement). Institutional investors such as **Legal & General Capital** also deploy substantial capital through their climate transition fund into London-based startups. Finally, **Inspired Evolution**, though South African-born, has a London office and focuses on clean energy and resource efficiency across Africa and Europe. These firms collectively represent a dynamic and well-capitalised ecosystem, actively deploying billions into innovations ranging from carbon capture and green hydrogen to sustainable agriculture and circular economy solutions.
