SponsorHound Sponsor intelligence for podcasts and newsletters
Find the brands that already sponsor shows like yours.
SponsorHound is a tool for your AI agent. Describe your show or newsletter, and your agent gets a ranked list of brands that advertise on similar ones, with the proof: dated, public ad reads, each with a short quote and a link.
Private beta, free for a small group of design partners. Works with Claude Desktop, Claude Code, Cursor, VS Code and other MCP clients.
"…this episode is brought to you by Example Electrolytes. Use code RUN for 20% off…"
Illustrative output with made-up brands. Real answers name real brands and link to each source.
Ask in plain words
Your agent does the digging. You send the pitch.
SponsorHound speaks the Model Context Protocol (MCP), so there's no new app to learn. Ask your assistant the way you'd ask a colleague:
"Which brands would sponsor my weekly running podcast? Show the evidence for the top 5."
"Who advertises on newsletters like mine about AI tools for accountants? Skip anyone inactive since August."
"Find 10 podcasts similar to mine, tell me who advertises on them, and draft a pitch to the best fit."
What your agent gets
Ranked brands, with proof you can check.
Ranked brands, with reasons
Brands that advertise on shows like yours, ranked by how similar those shows are, how often the brand appears and how recently.
Evidence on every brand
Dated sponsor reads: a quote of 240 characters at most and a link to the public episode or post.
Similar shows
Podcasts and newsletters close to yours, with their top sponsors, so you can see who your peers work with.
Fresh every week
Each answer says how current the data is. The catalog refreshes about weekly from public feeds.
Works in your assistant
Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, or any MCP client that sends a header.
Honest about limits
No audience numbers, rates or contacts. An ad read shows a brand advertised, not what it paid. Read more.
How the beta works
From request to first answer in minutes.
- Request access. Sign up with Google or your email. We open accounts in small batches.
- Create an API key in your dashboard. It's shown once; rotate or revoke it any time.
- Connect your agent with one command (Claude Code) or a short config block. See the setup docs.
- Ask, and tell us what's wrong. The beta's goal is to learn whether the top recommendations are plausible. Bad results are useful feedback.
Coverage today
Mostly English-language shows. Figures are approximate and change with each refresh.
Questions
Where does the data come from?
Only public podcast and newsletter RSS feeds that allow automated access in their robots.txt. No YouTube data, no private, paywalled or logged-in content. Sponsor mentions are extracted from the feed text by rules.
Which AI assistants work?
Any MCP client that can send a custom header to a remote (Streamable HTTP) server: Claude Code, Claude Desktop
(through the mcp-remote bridge), Cursor, VS Code, Windsurf and others. Web connectors that require
OAuth, such as claude.ai and ChatGPT, aren't supported in the beta yet.
What does it cost?
Nothing during the private beta. See pricing for the plans we expect to offer afterwards.
My brand or show is listed and I'd like it removed.
See opt-out and removal. Removals apply at the next weekly refresh.
