Four verticals and 75 types of business, all of them sitting on the same problem. For each one you get how to spot it from the outside, where you have almost certainly met one already, what actually hurts in the owner's own words, and the two lines that open the conversation.
Learn this and you can qualify a business type that is not even on this page. It is the whole filter.
Nobody can answer "who do you know" cold. Most people say they know nobody and then find eleven names in twenty minutes. Memory needs a prompt, not effort. Write down every name including the long shots, because a long shot costs you one message.
Open any one for how to spot it from the outside, where you would already know them from, what actually hurts, and what to say first.
None of these are rebuttals. Every one is a question that hands the problem back so the owner describes it in their own words. If you are arguing, the conversation is already over.
