Product overview
Carbnn is a two-sided marketplace. One side buys advertising, the other side sells it, and AI agents sit in the middle helping both sides move through the process faster.
Buyer side
Buyers are brands and the media agencies who plan and place media on a brand’s behalf. A buyer starts with a brief — what they want to advertise, to whom, and with what budget — and works with an agent to turn that brief into a proposal, and a proposal into a media buy. Nothing spends money without a human confirming it first. Once a buy is live, the buyer tracks delivery and proof that the campaign ran as agreed.
See the buyer guide for the full walk-through.
Seller side
Sellers are creators — people with an audience — and creator networks, which represent a group of creators to buyers as a single storefront. Sellers list their available inventory as deliverables (see the glossary below), and get discovered by buyers browsing or by agents matching a brief. Once a buy is agreed, the seller produces the work, provides proof it went out, and gets paid their share.
See the seller guide for the full walk-through.
Creator networks
A creator network represents multiple individual creators to buyers. It gives buyers one place to discover and buy across many creators at once, and gives smaller creators access to buyers they wouldn’t reach alone. Networks negotiate on behalf of their creators and take a share of the buy for doing so.
Agencies
An agency plans and buys media on behalf of one or more brands, the same way a creator network sells on behalf of one or more creators. An agency represents its brand clients when talking to sellers, and its clients see the resulting spend and delivery.
