Who already has your audience?

Search YouTube, the open podcast index and Bluesky for people publishing about your problem. Small creators come first on purpose — a 5,000-follower channel will actually reply to you, and a 500,000-subscriber one won't.

• · Only official, free APIs. Nothing here scrapes a platform that forbids it — no Skool, no Discord directories, no Substack crawling.
• · No email addresses, ever. You get the public profile, and you go and talk to them where they publish.
• · Audience size is shown only where the source actually reports it. The podcast index has no listener figures at all, so those say so rather than guessing.
• · There's no “fit score”. Whether someone is a good partner isn't something an API can tell you — that part is yours.

Publish to an audience yourself? Register as a partner — a human reaches out only when a specific app fits what you publish.
