$10m · Series A · Cleantech · London, UK
London-based Isometric has added a $10m extension to its Series A, taking the round to $50m, as Intercontinental Exchange (ICE) and nine other new backers join the company. The extension follows the $40m first close announced in June and brings Isometric's total funding across its seed and Series A rounds to $75m, according to the company.
The new investors are ICE, Acario Innovation, BY Venture Partners, Dubai Future District Fund, Earth VC, Motion Ventures, One Capital, Plug and Play, Verb Ventures and Legora founder Max Junestrand. AVP led the original Series A, backed by Lowercarbon Capital, Plural, John Doerr and Walter Kortschak.
Isometric plans to use the financing to expand its certification platform beyond carbon removal into industrial emissions, energy, fuels and materials. Its Certify product uses AI agents to cross-check evidence such as sensor readings, satellite imagery, supply-chain records and laboratory results, with independent verifiers handling expert judgement. The company says its certification is used by Microsoft, Anglo American, Boeing and JPMorgan Chase, and that it has been contracted across more than 16m tonnes of carbon removal and over 200 projects.
Certification is becoming transaction infrastructure
Industrial projects need to prove regulatory, safety and sustainability claims before buyers pay premiums, regulators issue permits or investors commit capital. If Isometric can make that evidence reusable and auditable, certification could shift from a slow project expense to infrastructure that helps transactions close without weakening independent oversight.
ICE brings market-data and exchange-infrastructure experience to that bet. The test is whether Isometric can carry a model developed in carbon removal into industrial emissions, energy, fuels and materials, where standards differ by sector. Its durable advantage will depend less on generic AI than on the protocols, audit trails and integrations that make each certificate credible.
