€7.4M
The seed round was led by Extantia with backing from the NATO Innovation Fund, Promus Ventures, and Fund F.
"This investment is a clear signal that Europe intends to lead in sustainable advanced-materials manufacturing. Our technology turns what is currently burned, buried or exported into a reliable, high-quality feedstock stream, strengthening supply chains for primes, OEMs, and government customers. With Extantia and the NATO Innovation Fund behind us, we’re now positioned to scale with urgency."
£10.0M
The oversubscribed round was led by Energy Impact Partners with backing from several climate and technology investors.
"We are laser-focused on doing the hard yards to improve the physical layer of the grid, specifically overhead systems. The AssetCool team is innovating at the nexus between robotics and materials science to bring meaningful improvements to an aging network. We’ve developed a new range of coatings systematically optimised for overhead lines that makes the grid more efficient and resilient – not by rebuilding it, but by enhancing what already exists."
£18.3M
Extantia Capital led the oversubscribed round, which will fund the construction of the company's first plant.
"We’re proving that plastic waste isn’t just a problem to solve—it’s a valuable resource waiting to be unlocked. Using the molecular precision of enzymes at an industrial scale, we’re building the solution set to make all plastics recyclable and doing so at a competitive price. This is what real circularity looks like."
£8.5M
The funding round was led by Extantia Capital and includes £2.4m in non-dilutive capital.
"We want our technology to set a new standard in the waste treatment and energy sectors,by not only optimising waste breakdown but by boosting methane production across the board"
