Viridi, a British DeepTech company that converts waste carbon dioxide into chemical products, closed a €2.6 million (£2.2 million) funding round led by Odyssey Ventures. The round also drew co-investment from Alphatron Impact Ventures, follow-on commitments from existing angels, and a strategic investment from TOP Ventures, the corporate venture arm of Thaioil.
Why it matters
Many industries rely on petroleum or environmentally harmful chemical processes to produce raw ingredients. Viridi's catalyst is designed to plug into existing factory equipment, letting manufacturers swap in captured CO2 as a feedstock without rebuilding facilities.
The round totals €2.6 million (£2.2 million), down from the €3.3 million Seed round Viridi closed in 2023. Its CO2-based anionic surfactant Vireya launched in 2025, but the announcement does not disclose production volumes or conversion efficiency figures.
The players
Viridi
A British DeepTech company that converts waste carbon dioxide into chemical products, spun out of the University of Southampton.
Odyssey Ventures
A venture capital firm that led the round and has backed the company's expansion into the United States market.
TOP Ventures
The corporate venture arm of Thaioil that joined the round as a strategic investor.
The details
Viridi was spun out of the University of Southampton School of Chemistry as ViridiCO2 in 2020. The company has a Joint Development Agreement with Zschimmer & Schwarz, and it plans to deliver its technology to market starting in Asia, where it expects to support future surfactant production.
Timeline
2020: ViridiCO2 founded as a University of Southampton spinout.
2023: Viridi closes a €3.3 million Seed round.
2024: TOP Ventures begins following Viridi's development.
2025: Vireya, the first CO2-based anionic surfactant, launches.
Earlier in 2026: Joint Development Agreement with Zschimmer & Schwarz announced.
The Big Picture
Viridi's approach extends carbon capture and utilization (CCU) processes that convert captured CO2 into fuels and chemicals, shifting the focus to surfactant production. The company's design aims to slot into existing factory equipment rather than requiring new facilities.
Manufacturers that adopt captured CO2 as a feedstock could reduce reliance on petroleum-based ingredients in products like surfactants. The change would depend on whether factories adopt the catalyst, a step that remains unscheduled.
The takeaway
Industrial chemistry is testing whether waste CO2 can replace petroleum as a raw ingredient without requiring factories to be rebuilt. Viridi's plug-in catalyst is one attempt to make that switch practical rather than purely theoretical.
What happens next
Viridi plans to deliver its technology to market starting in Asia, though no specific dates were provided.
