AdSworn vs SponsorSheep
Two marketplaces with a similar flow: list, book, approve, pay. The audience and the proof are where they split.
Facts checked 29 Sep 2026 · by the AdSworn team
SponsorSheep is a newsletter sponsorship marketplace: publishers list placements at flat prices, sponsors book and pay in full at booking, and publishers receive 75% of the booking value. Its terms say audience figures are provided by publishers and not warranted. AdSworn works the same way for web pages, but the audience numbers are read from Google, publishers keep 85%, and payment is held until the ad is verified live.

A similar idea, a different audience
SponsorSheep and AdSworn share a shape: publishers list inventory at flat prices, sponsors book without back-and-forth emails, the publisher reviews the creative, and the marketplace handles payment. SponsorSheep does it for newsletters; AdSworn does it for web pages, chosen by the searches that bring their readers.
SponsorSheep is new (its terms are dated 21 September 2026) and also offers a free database of which sponsors run in which newsletters, built by subscribing to and scanning newsletters.
Where the audience numbers come from
SponsorSheep's sponsor terms are plain that audience figures come from publishers and aren't warranted. It does check the ad went out, from the issues it receives as a subscriber.
On AdSworn, the audience numbers are read from the publisher's own Google account, read-only, page by page, with the date read. You see them before you book.
Fees and payment
Both keep the sponsor's price clean. SponsorSheep keeps 25% of each booking; AdSworn keeps 15%. SponsorSheep takes payment in full at booking; AdSworn charges when the publisher approves, holds it, and refunds in full if the ad is never verified live.
