Innovation Investment Capital has backed Sero in its latest funding round to accelerate the rollout of energy efficiency solutions for social housing.

"IIC’s investment is a vote of confidence in Sero’s vision and technology and was driven by a clear alignment between CCR and Sero, which both share the aim of using innovative solutions to drive down bills, cut carbon emissions and deliver better, more comfortable homes for residents. With this support, we will accelerate deployment of our energy-efficiency solutions, deepen partnerships with housing providers and unlock new pathways for sustainable growth."
— James Williams, CEO
Seed
£1.5M

The funding round includes participation from JamJar Investments, Cur8 Capital, Energy Mix Ventures, Project Ventures, and angel investor Vlad Yatsenko.

"Having the backing of some of the UK’s most respected investors, including JamJar and a founder of one of Britain’s most successful tech companies, is a powerful validation of our team, our mission, and the product we’ve built. We’re not just optimising energy; we’re creating a more intelligent, sustainable and user-centred way of living."
— Piers Daniell, CEO
Series B
£55.0M

The oversubscribed round included participation from Hitachi Ventures, Voyager Ventures, and Schroders Capital, alongside existing investors.

"Energy underpins every industry in the world, and yet no one has succeeded in course-correcting the fundamentally flawed way the markets work. For decades, the industry has tried to patch over the costly inefficiency of energy transactions with new utility brands and new promises. The real opportunity in energy looks a lot like what fintech did to banking: rebuild the core infrastructure, then let innovation explode on top of it."
— Joe McDonald
Pre-Seed
£2.4M

The pre-seed round was led by Visionaries Tomorrow and will support team expansion and platform development.

"The energy transition isn’t being held back by technology — it’s being held back by process. Permitting, siting, and regulatory complexity can delay critical projects by years. Nyxium was built to compress that timeline."
— Thiri Shwesin Aung, Founder and CEO
