Enterprises that turn proof into progress with Sunhat
.avif)
You know the progress you’ve made.
You just can’t prove it in time.
Policies buried in Legal. Metrics trapped in Ops. Reports lost in Finance.


By the time you chase them down, deadlines have passed and deals are gone.
Turn messy data into proof you can trust
Stop scrambling for answers. Connect your systems, trust your data, and deliver proof that lifts scores and closes deals.
Connect
Link people and systems where proof lives. From carbon
tools to ERPs to the teams who own the data.
"Sunhat turned scattered documents into a living knowledge center. My team collaborates instead of duplicating work, and the right answers are always at our fingertips."
Collect
Automatically gather proof. No more version confusion or chasing updates. Proof builds itself as work gets done.
Before Sunhat, finding the right information and attaching files to huge Excel sheets was a nightmare for me and key stakeholders. It often felt less like meaningful sustainability work and more like giving Excel tutorials.
Verify
See exactly what EcoVadis, CDP, or CSRD will ask before they do. Spot gaps, expirations, and risks before they cost you.
With Sunhat and Proof AI, I can instantly find previous answers or create tailored ones from our reports and policies.
Deliver
Send complete, source-linked proof for audits, assessments, or customer questionnaires.
Instead of manually scanning hundreds of report pages, we now let Sunhat's Proof AI bring everything together into one clear, ready-to-use answer.
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.
