For data holders
Health data holders will find Protege's focus and compliance support closer to their needs. Holders of general media or speech data may suit Defined.ai's catalog. With both, ask for the revenue share in writing, whether the platform keeps a copy, and whether listing is exclusive.
Where a broker differs
A marketplace usually lists data for many buyers. A broker negotiates one license at a time, which suits private archives that should not be listed and deals that need exclusivity. See broker vs marketplace.
