iSumio Ltd (EngagedX Ltd)

iSumio Ltd is a UK-based climate technology company and the software development arm of EngagedX Ltd, which was incorporated in England and Wales in 2012. The company develops Neoni® App, a ledger-based carbon accounting platform created to address structural weaknesses in conventional emissions reporting, particularly around Scope 3 consistency and auditability. iSumio’s work on Neoni® App originated from a Scottish Government innovation challenge launched in 2021, with the software entering public beta in 2023. The vendor focuses on applying financial accounting logic to emissions data, aiming to produce transparent, decision-useful, and assurance-ready carbon accounts. iSumio Ltd primarily serves organisations with complex supply chains, advanced reporting needs, and increasing exposure to climate-related financial and regulatory disclosure requirements.
