These kinds of services exist for flavor, absolutely, and I imagine they must also exist for odor (probably similar companies since so much of flavor is odor).

These kinds of services exist for flavor, absolutely, and I imagine they must also exist for odor (probably similar companies since so much of flavor is odor). I'm reminded of the silly Comedy Central show Nathan For You (where a comedian provides outlandish business advice to actual small businesses) where Nathan found a flavoring company to uniquely design a poop flavored frozen yogurt as a publicity stunt. I imagine an odoring business exists, but just isn't consumer facing, rather sells to brands we know, so we don't know who they are.
