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. We start with ESG and climate workflows, where trust breaks down fast when the evidence trail is weak.

Why this matters now
In the Nordic and EU context, 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. That is not only a messaging problem. It is an evidence problem.
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, with a Nordic/EU evidence and governance focus.
Varmennappi — the first product / MVP
An MVP for supplier proofs, time-stamped records, structured evidence collection, and audit-ready exports.
Evidence trails — the core thesis
Claims are easy to make. Substantiating them reliably is harder. We build the layer that keeps the proof attached.
Varmennappi is our first proof point, not our entire ambition. Over time, the same evidence logic can support adjacent workflows where claims, reviews, and accountability matter. But right now our focus is narrow: solve the first problem well.
How we work
We care less about polished ESG theatre 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.
Clear accountability
Who checked what, and when.
We build for the moment someone asks, “Show me the evidence.” The system should answer before the inbox chaos begins.
Who we work with
We are especially interested in conversations with teams handling reporting risk, supplier evidence, procurement workflows, or environmental-claim accountability.
Sustainability / ESG teams
Teams carrying reporting pressure and needing a cleaner evidence trail behind environmental claims.
Procurement and supplier teams
Teams collecting supplier proofs, validating inputs, and reducing last-minute documentation gaps.
Assurance, audit, and reporting partners
Partners who need structured records, clear timestamps, and exports that are easier to review.
Public-sector, ecosystem, and programme partners
Organizations shaping practical pilots, procurement models, and shared credibility around evidence-heavy workflows.
At this stage, we value sharp conversations, pilot contexts, and honest workflow feedback as much as commercial interest.

Work with us
We are looking for conversations with sustainability, finance, procurement, assurance, and ecosystem teams across the Nordics and the wider EU.
If you are dealing with evidence gaps, supplier proof, reporting friction, or environmental-claim scrutiny, let’s compare workflows.
We are open to pilots, partnerships, funding conversations, and public-sector collaboration — but the first step is simple: understand the problem well enough to build the right system.
