The Concept
The best time to ask for a referral is the exact second a customer says they love you.
Most CS agents wait for a "Referral Meeting." That is too late.
The Trigger
Automate it. When a user gives an NPS score of 9 or 10, trigger an immediate personal email from the Founder: "Saw you gave us a 10. That means the world. Is there one other VP of Sales you know who puts up with this same problem?"
