endorser
Product's paid advocate
An endorser is someone who publicly supports or approves of a person, product, or cause.
Celebrities often serve as endorsers for brands, lending their name and image to advertising campaigns.
In financial contexts, an endorser is specifically someone who signs the back of a check or other negotiable instrument, thereby accepting responsibility for payment if the original payer defaults.
The company hired a famous athlete as an endorser for their new sneaker line.
