The short version

Pick it if

  • You’re a creator looking for brands to pitch
  • You want to know how a tool decides what counts as a deal
  • You manage up to 10 creators and want a roster view

Skip it if

  • You need paid reads kept apart from affiliate codes
  • Most of your channels are under 50,000 subscribers
  • You want an API or a yearly plan

SponsorRadar is a self-serve YouTube sponsorship database built mainly for creators finding brands to pitch, with an Agency plan for talent managers. It has the biggest published index in our ranking: 1,508,556 deals across 101,149 channels and 21,736 brands on 29 October 2026. It’s also the only tool here with a public methodology. It reads each video’s metadata and, where available, its transcript, scores every detection, and only counts high-confidence ones on public pages.

That openness is why it ranks first, but the caveats are real. Its top brands include Gamersupps, StreamYard and Gfuel, which run creator codes, affiliate programmes and livestream tool links, so some “deals” aren’t paid reads. Deal prices are estimates, not observed rates. And it’s a one-person product launched in February 2026, with no independent reviews yet.

Pricing

Every plan is labelled “early access”, with Creator Pro shown struck through from $59 and Agency from $199. Paid plans start with a $1 seven-day trial and bill monthly. There’s no annual price and no published metering on contacts, so there’s no per-1,000 rate.

Using SponsorRadar

Signing up

Sign-up is through Google, with an email option on Agency. The free Creator tier needs no card. Paid plans start with a $1 seven-day trial, then bill monthly with no contract. SponsorRadar says connecting a channel takes about a minute.

Documentation

There’s no API, so there are no developer docs. The document worth reading is the methodology page: detection signals, the confidence threshold, exact counts and known limits, including thinner coverage below 50,000 subscribers. No other tool in the category publishes as much.

Support

Support is a single email address, the founder’s. There’s no help centre or status page.

EmailThe only contact listed on the site.

Verdict

8.1

The best place for a creator to start. It has the most data in the category, and it’s the only vendor that tells you what it counts and what it misses. Treat its brand rankings as leads rather than proof of paid deals, open the videos before you pitch, and expect the $29 early-access price to rise. If you want the sponsor segment behind each deal and a read on when to pitch, take Sponsorbook. If you’d rather pay $20 a month on a yearly plan, take GetSponsored.

Questions

Is SponsorRadar legit?

It’s a real, working product from a solo maker, David Park, launched in February 2026, and it publishes its method and live counts. There are no reviews on G2, Capterra, Trustpilot or Product Hunt yet, and no company name or address is published.

How much does SponsorRadar cost?

The Creator tier is free for one channel. Creator Pro is $29 a month and Agency $99 a month, each after a $1 seven-day trial. Both are labelled early access and shown struck through from $59 and $199, so expect them to change.

How does SponsorRadar detect sponsorships?

It fetches each new video’s metadata and, where available, its transcript, then looks for sponsor reads, disclosures in the description, and promo codes or affiliate links that resolve to a brand. Each detection gets a confidence score, and public pages only count high-confidence ones (vendor says).

Does SponsorRadar count affiliate links as sponsorships?

Affiliate links that resolve to a brand are one of its signals. Its top brands, Gamersupps, StreamYard and Gfuel, suggest creator codes and tool links make up a share of the counts.

Are SponsorRadar’s deal prices real?

No, they’re estimates: a niche CPM range applied to the median views of a channel’s last 12 long-form uploads. Its examples are $10–25 CPM for gaming and $40–80 for finance (vendor says).

Does SponsorRadar work for small channels?

Less well. It says coverage is strongest above 50,000 subscribers and thinner below, so numbers for small channels undercount.
