About DataSolmu
Evidence-first software for ESG and climate claims
DataSolmu builds tools that help teams turn claims into defensible evidence - with supplier proofs, timestamps, structured records, and audit-ready exports.
Finnish company. Registered May 2025. Jyväskylä.
Why this matters now
Sustainability reporting and environmental claims face growing scrutiny. Teams are increasingly expected to show what was claimed, what supports it, when it was checked, and who can stand behind it.
We build for organizations that would rather have the trail ready from day one than scramble for proof during reporting, procurement reviews, or stakeholder questions.
What we build
DataSolmu is building an evidence-first layer for ESG and climate-related workflows.
DataSolmu - the company
A Finnish software company building evidence-first tools for ESG and climate claims.
Varmennappi - first product
An MVP for supplier proofs, time-stamped records, structured evidence collection, and audit-ready exports.
Evidence trails - core thesis
Claims are easy to make. Substantiating them reliably is harder.
How we work
We care less about polished ESG theater and more about proof that survives scrutiny.
Traceability
What was claimed, what supports it, and when it changed.
Defensibility
Records that can stand up to internal review and external questions.
Structured exports
Evidence that can be reused across reporting and procurement workflows.
Practical workflows
Built for real teams, not idealized spreadsheets.
