Viridi, a UK-based climate technology startup developing catalysts that convert captured carbon dioxide into chemical ingredients, has raised £2.2 million in a funding round led by Odyssey Ventures. The round included participation from TOP Ventures, Alphatron Impact Ventures and existing angel investors.
TOP Ventures, the corporate venture capital arm of Thailand’s Thaioil Group, joined as a strategic investor. The investment will support Viridi’s technology development, team expansion and commercial growth across Asia and the United States.
Founded in 2021 by Dr Daniel Stewart and Professor Robert Raja as a spinout from the University of Southampton, Viridi develops catalyst technology that enables chemical manufacturers to use captured CO₂ as an alternative carbon source in industrial production.
The company’s technology converts captured carbon dioxide into chemical building blocks used in products traditionally manufactured from fossil-derived or palm-based materials. Its catalyst platform is designed to integrate with existing manufacturing infrastructure, allowing producers to adopt alternative chemical processes without replacing their production facilities.
Viridi’s initial commercial focus is on CO₂-based surfactants, which are ingredients used in detergents, shampoos, cleaning products and other home and personal care formulations.
In September 2025, the company launched Vireya, its CO₂-derived anionic surfactant. In February 2026, Viridi entered into a joint development agreement with German specialty chemicals manufacturer Zschimmer & Schwarz to support the scale-up and adoption of its surfactant technology.
The latest investment also builds on Viridi’s earlier £3 million seed funding round in 2023, which was led by EQT Ventures and supported the development and commercialisation of its carbon utilisation technology.
Led by co-founder and CEO Dr Daniel Stewart, Viridi plans to work with its investors and industrial partners to advance its manufacturing technology and establish commercial opportunities in international markets. TOP Ventures brings access to Thaioil’s industrial expertise and Asian chemical manufacturing network, while Odyssey Ventures is supporting the company’s expansion into the US.
