Brand safety on Publsh is built into the shape of the deal: nothing is randomized, the brand picks the creator on purpose, and every creative clears review and the creator's approval before it can render.
Safety built into the shape of the deal rather than policed after the fact. Nothing is randomized: a brand picks the creator on purpose, and every creative clears review and the creator's own approval before it can render.
Because a placement only happens when both sides have said yes, there is no bad pairing to catch later. See you approve every ad.
