What they did
Added a button in the product UI with a rainbow border: 'Book a call with the team if you want 7 days of extra access.' It linked straight to the founders' Calendly. Both co-founders took ~20 calls a week every week since August 2025, interviewing users with a prepared question list, with an AI note-taker on each call.
What happened
~2,000 customer calls; founder credits calls as the biggest driver of how Fastlane was built and its ~$69K MRR two months after launch
