Real insights from your customer data
How it works
Three steps. Fifteen minutes.
Step 1: Upload your customer list.
Any spreadsheet works. No setup project.
Step 2: See who's at risk.
Every account gets a health score with plain reasons.
Step 3: Know what to do.
Each alert comes with a simple action plan.
Built for busy owners, not data teams.
Early warning
You typically get 6 to 8 weeks of notice before a customer walks. Time to act, not react.
Any business with repeat customers
Distributors, agencies, insurance, property management, software. If revenue repeats, this works.
Private by design
Your customer data is protected and never shared or sold.
The alternative is finding out too late.
Spreadsheets show you what already happened.
Gut feel tells you when the customer is already gone.
Gran Minerva tells you while you can still fix it.
