The short version
Pick it if
- You’re a brand or agency that wants search and outreach in one place
- You want an API and MCP server without an enterprise contract
- You’ll pay yearly, at $53 a month
Skip it if
- You want to judge the data before paying
- You’re a creator looking for brands to pitch
- You need a big channel index to search
Sponsorship.so is built for brands and agencies first. You search creators and brands, see past sponsored videos and competitors’ sponsors, find creator emails, and run outreach from a built-in CRM with AI drafts and a Kanban board. Pro at $89 a month also includes CSV export, an API and an MCP server, which is more than most rivals put on their standard plan.
It ranks last because there’s so little to check before paying. The site claims 250K+ channels and “thousands of brands” but gives no sponsorship totals, and it says detection is automated with manual verification on top without naming the signals. It has no reviews beyond one Product Hunt rating from 2024. There’s no free plan and no trial, only a free sample and a 14-day refund.

Pricing
Credits pay for new email lookups and AI drafts. Failed lookups are free, and contacts already on the platform don’t use credits. Counting credits as lookups, Pro works out at $356 per 1,000, or $212 billed yearly. The $89 Pro price looks unchanged since 2024.

Using Sponsorship.so
Signing up
There’s no free plan and no trial. You can ask for a free example before buying, and refunds are available within 14 calendar days of purchase. After that you’re on Pro or Agency.

Support
Support is by email, with priority support on Agency.
Verdict
A sensible all-in-one for a brand that wants research, creator emails and outreach in one place, but it asks for $89 before showing you anything you can measure. Most brands should start with ChannelCrawler, which has a far bigger index and a free trial. If you’d rather hand the whole job off, ThoughtLeaders runs sponsorships for you.

Questions
Does Sponsorship.so have a free plan or trial?
No. It offers a free example instead, and refunds within 14 calendar days of purchase. Some third-party lists, including vidIQ’s, still describe it as free to browse, which is out of date.
How much does Sponsorship.so cost?
Pro is $89 a month, or $53 billed yearly, with 250 credits. Agency is $199 a month, or $119 billed yearly, with 1,000 credits, up to five team members and priority support.
What do Sponsorship.so credits pay for?
New email lookups and AI email drafts. Failed lookups don’t use credits, and contacts already on the platform can be viewed free on paid plans.
How does Sponsorship.so detect sponsorships?
It says it analyses YouTube videos with automated systems and adds manual verification on top, with data updated daily. It doesn’t publish which signals it uses.
Is Sponsorship.so for creators?
Mainly for brands and agencies. Its Agency plan also targets agents managing several creators, but its contacts are creator emails for brands, not brand contacts for creators. Creators should start with SponsorRadar or Sponsorbook.
