# Pay Per Booked Meeting Assessment with Leaderra

> Fifteen minutes, no deck. We look at where your leads go cold today — your response times, your channels, and the gap between a form fill and an actual human. Then we run the follow-up live on your own details so you see it work. You leave knowing what a booked meeting costs you now, and what it would cost with this running. If it isn't a fit, we'll tell you on the call.
