Fast Track 100

Three university friends set up this technology security firm, which claims to have developed the first platform that uses machine learning to protect against human error. Its platform prevents emails containing sensitive data being sent in error, such as through spear phishing, accidental data loss and other “non-compliant activity”. The company says its machine learning software has been trained on 1bn emails, and its customers include Rightmove, Arm, and the BMA. Founded in 2013 by Tim Sadler, 31, Tom Adams, 31, and Ed Bishop, 30, the firm now has 150 employees across its offices in London and San Francisco. It has raised $59m to date, from investors including Sequoia Capital, Balderton Capital, and Accel.
