Overview
Persefoni is a cloud-based carbon accounting and climate-disclosure platform that measures Scope 1, 2 and 3 greenhouse-gas emissions and turns them into audit-ready reports for regulators, investors and customers. It is aimed at organizations that need to comply with mandatory or voluntary climate-disclosure regimes such as CSRD, ISSB, SEC climate rules, California SB 253 and SB 261, TCFD and CDP.
The platform is organized around measuring, reporting and reducing emissions. It offers spend-based Scope 3 estimation with a path to refine estimates toward activity-based actuals, a Sustainability Report Builder for major disclosure frameworks, decarbonization and net-zero target modeling, and a dedicated Financed Emissions module that lets banks, asset managers and portfolio companies calculate financed emissions aligned to the PCAF standard. An Integration Hub lists 26 pre-built connectors (AWS, Concur, Expensify, Navan, Coupa, Egencia, Google Sheets, and 9,000+ utility providers) that automate emissions-activity data collection, and PersefoniAI adds a GPT-style Copilot plus anomaly detection across the emissions dataset.
Persefoni ships in two tiers: a free, single-user Pro plan with unlimited assets and historical reporting years, and a quote-based Advanced plan adding multi-user roles, SSO/MFA, advanced analytics and a dedicated customer success manager. The company is privately held, headquartered in Mesa, Arizona, with additional offices in Toronto, London, Munich, Tokyo and Singapore, and its Sustainability Advisory Board includes the founders of CDP, SASB and TCFD.
