How do I stop unqualified people booking my discovery calls?
Put a priced question in front of the call. Anyone who will not pay for an answer was never going to pay for the programme, and you find out without giving away 45 minutes.
Why free calls select for the wrong person
A free call is attractive in exact proportion to how little someone intends to spend, which is why the calendar fills and the pipeline does not.
What the paid step tells you
The question shows whether their situation is one you can help with, and the payment shows they have budget. Offer the call to the ones worth it, having been paid for the triage.
