CyLon Scale has evolved from and replaced the CyLon accelerator programme which we ran from 2015-2020, accelerating over 100 companies to a portfolio value of over $1bn.

CyLon Scale builds on everything we have learned. It focuses on the elements that our best Founders valued the most, while removing any disruption to the day-to-day running of your business.

CyLon alumni have gone on to raise investment from leading investors including Sequoia, Goldman Sachs, LocalGlobe and many others, and to win customers across global Enterprise.
