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.
