London’s climate tech startups raised all-time-high levels of venture capital investment in 2023

London, 17th January 2024 – London’s technology sector demonstrates resilience and sustained growth, according to new data from London & Partners and Dealroom. The data shows that London startups collectively raised over $12.9B in venture capital (VC) investment in 2023, marking a return to pre-pandemic levels of investment following a global pullback in VC after a spike in 2021 and 2022, with the Climate Tech sector showing a clear lead.

The data shows that London continues to lead as Europe’s number one tech hub with London’s startups having raised almost as much investment in 2023 as the next three European cities combined (Paris, Stockholm, and Berlin).

Globally, London ranks as the fourth city by VC raised, after the Bay Area, New York, and Boston. The report also shows that the UK remains the third country globally by venture capital raised in 2023, after the US and China.
