UK cybersecurity startup Cytix raises €6 million Series A to tackle AI-driven software change risks

Cybersecurity startup, Cytix, has announced a €6 million ($7 million) Series A funding round to accelerate the company’s mission to tackle the problems created by rapid software change.

The round has been led by Northern Gritstone, a UK venture capital and investment firm that funds science and technology startups in the North of England, with participation from existing investors, Auriga Cyber Ventures and NPIF II – PXN Equity Finance, which is managed by PXN Ventures as part of the Northern Powerhouse Investment Fund II (NPIF II).

Speaking about the funding, Ben Armstrong, CEO of Cytix says: “We chose Northern Gritstone for their conviction in investing in DeepTech companies in the North of England with global ambition.

“Northern Gritstone and Cytix share the belief that software change is becoming a key risk for organisations and those that build software need a solution that scales with the current pace of development. We’re also grateful to the existing investors that have backed us since the early days and increased their commitment because they’ve seen the thesis play out.”

Duncan Johnson, CEO of Northern Gritstone, says: “The explosion of AI-assisted software development has led to a race to ensure software implementation remains secure. Cytix’s platform aims to help enterprises take a realistic approach, recognising where change carries the most risk whilst allowing businesses to innovate. Northern Gritstone is proud to support another ambitious Manchester-based business in an exciting phase of its growth.”

The company, founded in 2020, says software change is becoming a distinct risk for every organisation as AI-assisted development, agentic workflows, and continuous delivery have outpaced the security models built to govern it.

The funding will be used to accelerate the roll out of Cytix’s newly launched change risk platform. The platform is designed to address the questions raised by rapid software change: whether security should care about the change, what risk it introduces, and what the required action should be.

The Series A round will help Cytix reach customers in enterprise and regulated businesses where change governance is a regulatory obligation. Customers can access the platform either directly with Cytix or through its managed service partnerships with NCC Group and KPMG.

“Software is changing,” continues Armstrong. “AI-assisted development means change now happens at machine speed. Meanwhile, very few security leaders have control over, or understanding of, those changes from a risk perspective. Right now, existing tools can tell you what vulnerabilities you have, but can’t tell you about the risk. We launched Cytix’ change risk management platform to get control of that risk.”
