"Interesting" is the polite version of "I don't understand." When a buyer truly gets your offer, they don't say it's interesting. They say "how does that work?" or "can you do that for us?" or "my friend needs this."
"Interesting" means they recognized that you're smart and passionate, but they couldn't figure out how your expertise applies to their life. The offer didn't connect to a problem they have. So they gave you the most gracious exit they could.
The fix: lead with the problem, not the solution. Instead of "I help leaders build high-performing teams," try "I help VPs who just inherited a team that's underperforming get them to quota within 90 days." The first version is interesting. The second version is actionable. The difference is specificity. (For more on building that specific sentence, see How to Explain What You Do in One Sentence.)
If someone asks "so what exactly do you do?" after you've already told them, the offer didn't land. They heard words. They didn't hear a promise. This usually happens when you lead with your methodology, your background, or your credentials instead of the outcome.
"I'm a certified executive coach with 15 years of Fortune 500 experience specializing in transformational leadership" is a bio. It's not an offer. The fix: answer the question before they ask it. "I help newly promoted VPs stop putting out fires and start running their team like a system." Now they know what you do without having to ask.
