The funding will support the Sheffield spinout in moving its porous silicon anode technology from the laboratory toward commercial deployment.
"Our focus from day one has been on building a new type of silicon battery material that can be produced at scale and integrated into existing battery supply chains. This investment allows us to move beyond proof-of-concept and concentrate on scaling a product that delivers real commercial value to battery manufacturers, without introducing unnecessary cost or complexity."
The oversubscribed round was led by Oyster Bay Venture Capital to advance research and development on plant-based materials.
"Once optimised and patented, we will raise our next round to co-locate this continuous process alongside a brewery, enabling immense production outputs. We initially applied our technology to beer breweries and whisky distilleries because of their robust supply chains. As part of this raise, we will also prioritise commercial partnerships to introduce products to the fashion and other industries, starting on a small scale."
Vertex Exploratory Fund and Clean Growth Fund co-led the £4m round to accelerate international expansion.
"The Vertex Exploratory Fund actively seeks out disruptive frontier technologies with climate as one of the core themes in our investment strategy. measurable.energy stood out as one of the most promising startups in the UK in the climate space, offering a low-touch, intuitive, and compliance-ready solution that effectively reduces power waste. The company is at the forefront of providing the tools necessary to drive positive change and the Vertex Exploratory Fund is proud to partner with them on this journey."
Plural led the Series A round to help the London based startup expand its team and scale its super-brain solution.
"This funding is yet another milestone for Oriole following a year of rapid pace and growth. This is a booming market desperate for solutions and our ambition is to create an ecosystem of photonic networking that can reshape this industry by solving today's bottlenecks and enabling greater competition at the GPU layer. Building on decades of research, we're paving the way for faster, more efficient, more sustainable AI."
The round was led by BGF, Shell Ventures, and Move Energy alongside existing investors Barclays and Clean Growth Fund.
"We are thrilled to have BGF and Shell Ventures support in our mission to decarbonise cold chain logistics. Their investment, alongside the continued backing of our existing investors, is a real validation of Sunswap’s journey to date. This funding will be instrumental in accelerating our growth and expanding our presence in the UK and European markets. It will enable us to ramp up production, support further customer trials, and invest in the development of our zero-emission technology. Together, we will work towards a cleaner, greener future for cold chain logistics, helping businesses meet their sustainability targets."
