Persefoni

Persefoni is a US enterprise carbon management software company founded in 2020 in Tempe, Arizona, by a team with backgrounds in energy and finance. The company was built on the idea that emissions accounting needed the same rigor and auditability as financial accounting, and it now helps large organizations measure, disclose and manage greenhouse gas emissions under multiple regulatory regimes.

The Persefoni platform ingests activity data across Scope 1, 2 and 3 categories, applies emission factors and generates audit-ready reports aligned with frameworks such as CSRD, TCFD and PCAF. It includes supplier engagement tools for Scope 3 data collection, a financed-emissions module for banks and asset managers, and AI-assisted anomaly detection. Persefoni serves more than 10,000 corporate and financial-services teams, including Snowflake, Elevance Health and Under Armour.
