Viridi, a British DeepTech that enables the transformation of waste carbon dioxide into chemical products, has closed a €2.6 million (£2.2 million) round to scale their technology, strengthen its team and support its expansion into Asia and the US.
The round was led by Odyssey Ventures, with co-investment from Alphatron Impact Ventures and follow-on commitments from existing angel investors. TOP Ventures, the corporate VC arm of Thaioil, came on board as a strategic investor.
This follows their €3.3 million Seed round in 2023.
Dr Daniel Stewart, CEO of Viridi, says: “Having a strategic partner like TOP Ventures look closely at our technology, see its value and choose to back it at this stage is strong validation of what we’ve built. We’ll be working closely with them to deliver our technology to market, starting in Asia. With Odyssey Ventures supporting our growth in the US, we now have partners who can help us take CO2-based surfactants to the world.”
Viridi’s raise comes amid a series of European investments in carbon utilisation and alternatives to fossil-derived industrial materials in 2026.
Belgium’s D-CRBN secured €17.5 million to convert industrial CO₂ into chemical building blocks, while Switzerland’s Seprify raised €13.4 million for cellulose-based ingredients.
In the UK, Uplift360 secured €7.4 million for composite regeneration, Sparxell raised €4.2 million for plant-based colourants and HexSeed received over €700,000 for CO₂-derived diamond coatings.
Alongside other comparable rounds, these investments and Viridi’s funding total more than €60.3 million, reflecting a defined sample rather than overall sector investment.
Vivat Wongnirund, Vice President-New S-Curve Business Development of Thaioil, adds: “We have followed Viridi’s development since 2024 and have been impressed by its progress, particularly in CO2-based surfactants. The technology has been tested in real manufacturing environments and shows strong potential for integration into existing industrial operations. Viridi’s approach to using captured CO2 as an alternative carbon input is highly innovative.
“This investment gives Thaioil exposure to an emerging technology that fits our future growth strategy in disinfectants and surfactants. We see this technology supporting the future development of surfactant production in Asia and beyond.”
A spinout of the School of Chemistry at the University of Southampton, ViridiCO2 was founded in 2020 and makes a special chemical ingredient (a catalyst) that helps factories turn recycled carbon dioxide (CO₂) pollution into useful materials for everyday products.
Normally, industries use petroleum or chemical processes that harm the environment to make the raw ingredients found in things like liquid detergents, cosmetics, glue, and mattress foams. ViridiCO2’s technology plugs right into existing factory equipment, allowing manufacturers to swap out those dirty fossil fuels for captured CO₂ waste without having to rebuild their facilities.
The technology is designed as a platform that can be applied across multiple classes of chemicals using existing manufacturing infrastructure.
Surfactants, key ingredients across home and personal care, are the first major application, with the potential to extend into other areas of chemical manufacturing, and, ultimately, remove fossil feedstocks from the supply chain entirely.
Ali Mitchell, Managing Partner, Odyssey Ventures, said: “Our commitment is to grow UK and European deep-tech companies that are solving some of the world’s most fundamental problems. Viridi is exactly that kind of company. Combined with a strategic investment from TOP Ventures, our support gives Viridi reach across both the US and Asia as it moves towards commercial deployment.”
Today’s investment builds on the launch of Vireya, Viridi’s first CO2-based anionic surfactant, in 2025 and the company’s Joint Development Agreement with Zschimmer & Schwarz, announced earlier this year, to accelerate the scale-up and market adoption of Viridi’s technology for sustainable surfactants.
