CyLon Scale

The CyLon Scale programme is tailored to give leading security startups the support they need to succeed in a uniquely challenging industry.

We have worked with over 100 cyber startups from around the world since launching in 2015, and have built a deep understanding of both the challenges and opportunities faced by entrepreneurs in this space.

Our new CyLon Scale programme builds on everything we have learned. Over a six month-period, we focus on helping you win customers, meet investors, get advice directly from CISOs of leading companies, and much more.

Applications are open all year around.

No equity

The CyLon Scale programme is free to all participating companies, and we don’t take any equity. We simply ask that you grant us the opportunity to invest in your next round, so we can support you further along your journey.

No need to relocate

We operate much of the programme on a virtual basis, supplemented by in-person events in Europe, Asia and the US. You don’t need to relocate in order to participate, and content is structured to accommodate all timezones

No interference with running your business

We don’t want to interfere with everything you’re doing to grow your company, so the time commitment is flexible and averages around 1 day per month.

“Thanks to its laser focus on cyber security, CyLon supported Zamna with the best contacts in the industry. This included some of our critically important first clients.”



Do you help organisations and people to live and work more securely? Then you’re in our sector.


Ideally suited for companies between Seed and Series A. If your solution isn’t in the market yet but you have great team credentials or think you have a unique piece of IP, we would still love to hear from you.


We aren’t limited by geography, and welcome applications from teams all over the world.

“If you’re a cyber startup, apply to CyLon. Your ambitions will be met with practical support to see you on your way to success.”


The new CyLon Scale programme has evolved from the CyLon accelerator programme which we ran from 2015-2020, accelerating over 100 companies to a portfolio value of over £500m. CyLon Scale builds on everything we have learned, and focuses on the elements that Founders want most.

It offers you the best package of support possible while not disrupting 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.
