Sponsor the Facility and mentoring services that accelerate the development of early-stage climate-tech companies.

Together, we can pave the way towards a more sustainable future by empowering members to contribute to the greater good

London GreenCity is an accelerator for early-stage technology ventures focused on technologies addressing the causes and impact of climate change

Data on accelerators show that participating firms have a higher success rate in bringing technology to market than those that have not participated.

London GreenCity will offer a dynamic, physical, collaborative environment for seed- to Series B-stage ventures, providing the facilities and tools important for the development of their product offerings.

There are several pockets of innovation around the U.K., supporting start-ups and focused in specialized areas such as fintech, insurtech, EV’s and fusion. London’s eco-system, however, does not have a venture accelerator focused on a broad array of climate technologies entering the commercialization phase even though the U.K. is the source of substantial innovation in this area.

Finding solutions to climate change requires accommodating physical technologies, e.g., process technologies, material science, etc. Relevant accelerator models are the LA Cleantech Incubator (LA), Greentown Labs (Boston), and mHub Chicago.

London GreenCity will provide members with space for work, meetings, and product development, as well as mentorship and access to financing networks and global partners for collaboration.
