Make data driven decisionson correct, updated CRM data
Vainu matches every account in your CRM and keeps it correct. Automatically, every day, across the Nordics.




Know every customer completely, without anyone keeping it that way.

Nobody updates it. It updates.

The whole company, inside the account.
Your team never leaves the CRM, and never works from a half-filled account again. Swipe through the four CRMs.

When the customer's situation shifts, your system hears it first.
The change lands as a task, a field or an alert where your team already works.

The same sync, delivered on the terms that suit your team.



What a data team asks first
You map each Vainu field onto a property you already have, custom ones included, and set what it may do when it lands. Nothing is written that you did not map.
Only what you allow, field by field: Vainu wins, yours wins, never overwrite, or read-only. A field with no rule on it is never written.
Against the register: fuzzy names, former names, wrong org numbers, duplicates, worksites filed as the parent. What does not resolve is reported back, not guessed.
One async call returns a whole country as a JSONL stream, and changes arrive as webhooks into your warehouse rather than a poll you schedule.
Yes, the sync runs both ways. Share what you already know about a company and it comes back attached to the same record, alongside ours.
Then use Vainu Custom Integration: a one-way push to any endpoint you can address, in the shape you asked for. No connector required.
