Yeah, this. The actual buyers probably aren't the creators themselves - they're the ones who need to reach lots of creators fast. Agencies, influencer platforms, brands already running sponsorships. Those people live with the pain of "how do I actually get a reply from this person without burning hours on contact forms."
If you're cold emailing that crowd, don't pitch the whole product vision. Keep it tight: "I can pull direct contact info for creators you already want to work with, here's one example." One clear outcome, one clear use case. Makes the value click faster than onboarding drop-offs.
Also, brace for the "is this legal / against YouTube TOS?" question. Someone will ask it within the first five replies. Have that answer ready.
