About Northzone
Northzone was founded in 1996 and is headquartered in London, with offices in the Nordics and New York. Its most recent flagship fund is a €1 billion vehicle announced in September 2022, and CB Insights counts ten funds in total. In 2026 the firm added Sam Endacott as a London-based partner. He came from Firstminute Capital and focuses on applied and physical AI at seed to Series B.
Northzone led the $200 million growth round for Blitzy, an AI platform for autonomous software development, at a $1.4 billion valuation in May 2026. Its portfolio page also lists AI companies such as XBOW, which works on autonomous offensive security, and Tandem Health, which is focused on reducing administrative work for doctors. The firm's AI mandate now sits partly with Endacott, who covers early-stage applied and physical AI. Lounge's deals desk shows further Northzone-led AI seed rounds in 2026.
Public sources describe Northzone as investing at the seed, Series A and Series B stages. A third-party directory, vcsheet.com, lists an average check size of $1M to $30M, but this figure is not stated by the firm itself.
