Centralise sales data.
All customer data in one place, and all your tools talk to it: email, calendar, CRM, invoicing and your AI tools. If a tool already works well, it stays. If it does not, we clear it out.
In short
Your salespeople spend half the day searching.
Five tools
Email, Excel, CRM, invoicing, WhatsApp. Nothing is in one place.
Duplicates
The same customer three times, with three phone numbers.
Silent customers
Nobody knows who has not ordered anything in eight months.
Your tools now talk to each other.
Files, databases and CRMs come together in one system. Your LinkedIn messages and your call list start from there.
We work with files and databases such as Excel, Google Sheets, CSV and SQL, and with CRMs such as Odoo, Teamleader Focus, HubSpot, Pipedrive, Salesforce, Microsoft Dynamics 365, Attio, Zoho CRM, monday CRM, Notion, Airtable and Close.
CRM
The heart. Every customer once, with all conversations, deals and signals attached.
Email and calendar
Every email and every meeting lands with the right customer automatically. Nobody retypes anything.
LinkedIn and telephony
Messages, calls and replies land in your CRM. You see who spoke to whom, and about what.
Quotes and calculation
A quote in minutes instead of hours. Prices and margins calculate themselves, and every quote sits with the right deal straight away.
Invoicing
A signed quote becomes an invoice automatically. You see who bought what and who is going quiet.
AI tools
ChatGPT, Claude or Copilot work with your customer data, with the right permissions.
Three weeks of building, then keeping it clean every month.
Which tools, which data, how messy? You get one score.
Merge duplicates, enrich, align fields, agree on standards.
What you already use now talks to each other, including your AI tools. With permissions per role.
A call list with buying signals, a Datascore and one improvement.
What your salesperson sees every Monday.
A call list with buying signals
Who you call today and why. The reason is attached.
All open deals in one overview
Every deal, every stage, on one screen. No more Excel next to your CRM.
A Datascore and one improvement
How clean your data is this month, and what we tackle now.
Karst brings your data together and keeps it clean.

What customers ask us.
1Do I need to buy a new CRM?
No. If a tool already works well, it stays and we connect it. Only when something does not work do we clear it out.
2What is the free audit?
We look at your tools and your data and give you one score: how clean it is, and what the first improvement is. No strings attached.
3How long does it take?
Three weeks of building: audit, clean up, connect. After that a short round every month to keep it clean.
4What happens with duplicates?
We merge them, fill in missing fields and agree on standards so they do not come back.
5Who is allowed to see what?
We define that per role. A salesperson sees their customers, a manager sees everything, an AI tool sees only what it needs.
6Will my AI tools talk to my CRM too?
Yes. ChatGPT, Claude or Copilot only get the customer data they need, with permissions per role. So your team works with your customers instead of with generic examples.
Now step 3: train your team.
Each step builds on the previous one. You do not have to start at step 1.
