Fair to both. Here's the honest version.
What Book a Sponsor does well
- Does the outreach for creators: it finds the buyer and sends the pitches.
- No commission on deals, and a money-back promise if no sponsor replies within 30 days.
- Lots of free tools for creators, like a media kit generator and sponsorship calculator.
Where Radar Lab is different
- Radar Lab works for the buyer, not the seller: it never pitches you, it helps you choose.
- Newsletters are ranked by fit for your buyers, starting from your website.
- Every sponsor comes with the actual ad and issue date, so you can see what worked for others.
- You see where competitors sponsor, which newsletters they come back to, and which ones none of them have found yet.
Should you pick Book a Sponsor or Radar Lab?
It mostly comes down to which side of the sponsorship you're on.
If you sell newsletter sponsorships
Pick Book a Sponsor
- You're a creator and want someone else to pitch brands for you.
- You run a podcast or YouTube channel as well as a newsletter.
If you buy newsletter sponsorships
Pick Radar Lab
- You're a brand getting sponsorship pitches and want to judge them with real data.
- You want to find good newsletters yourself, before the pitches arrive.
Can you use both? Not usually: they sit on opposite sides of the same deal. A creator might use Book a Sponsor to reach you, and you'd use Radar Lab to check the newsletter before saying yes.
