Sunhat

Sunhat is the Proof Company that provides a Collaborative Proof Platform and Proof Services for sustainability, compliance, and quality teams that must respond to ESG ratings, regulations, customer questionnaires, and audits. The platform centralizes supporting documents in a Proof Library and uses AI to link each answer to its source document, so answers can be reused across frameworks such as EcoVadis, CDP, CSRD, PPWR, and ISO. Customers can use the Proof Platform directly, or engage Sunhat's Proof Services team, which completes the assessment and reviews the result before submission. Published customer results include an average increase of 12 EcoVadis points.
