Stop managing different questionnaires in different silos.
Sunhat turns your sustainability and compliance data into a unified Proof Library, so you are continuously ready for EcoVadis, CDP, CSRD, and every customer request in between.

Enterprises that already turn proof into progress with Sunhat
















































You have the data.
You just can’t find the evidence.
Your experts know the answers, but that knowledge is trapped in emails and local sharepoints or excel sheets.
Teams lose weeks chasing documents and formatting answers.
Searching hours for the correct document
You know the policy exists, but is it the latest version? Is it signed? You waste valuable hours playing detective across SharePoint folders just to answer one simple question.
Answering the same question over and over again
You just answered "Do you have a Human Rights policy?" for EcoVadis. Now a customer asks the same. Without a central memory, you end up doing the work all over again.
Missing connection between answers and proof
A PDF stored in a folder isn't proof. Without knowing exactly which requirement it satisfies or who approved it, your data is just digital clutter that cannot be used to verify a claim effectively.
Build your Proof Library for
every Use Case
Sunhat connects your scattered data into one Proof Library.
Instead of asking colleagues for the same document ten times, you work from a single source of truth that is checked, approved, and ready to reuse for any use case.
Your Proof is Everywhere. Now it’s Together.
No more hunting through SharePoint, checking Mails, or chasing down Excel files. Sunhat connects all your systems and documents into one verified source so proof is instant, not impossible.
