Is there a word for the author of a testimonial about a product or service. I thought perhaps "Testimonee" or something similar but that's not a word.

  • Based on this, I think 'referee' may work: english.stackexchange.com/questions/50291/… "a person appointed to examine and assess for publication a scientific or other academic work." Commented Apr 15, 2016 at 15:24

    @KenGregory - No, a referee is one who examines and assesses a referee might then examine and assess the testimonials (say for publication) they do not author testimonials. That’s what a testifiier does.

    @Jim - Fair point. Perhaps 'reference' would have been a better suggestion. Commented Apr 15, 2016 at 15:47

One who gives testimony, or attests, is an attestant. In your context of "product or service", you might want to also consider "reviewer".


One who vouches for the quality of some product could be called a voucher, which according to Merriam-Webster is "a person or thing that vouches for the truth of some statement, etc."


Oxford Dictionaries On-Line, gives as its second meaning of referee (after the obvious sporting one):

A person willing to testify in writing about the character or ability of someone, especially an applicant for a job. (It is marked as BRITISH)

A third definition, which is not marked as necessarily British is:

A person appointed to examine and assess for publication a scientific or other academic work.

The second definition, in Britain, would appear to be the one you want. But if you are looking for something American I'm afraid I can't help you.

  • Yup, that's how this Brit says it.

Product spokesman, spokeswoman, spokesperson.


"Publicly referenceable customer" is what one product marketing person at my company calls a customer that agrees to be cited publicly.
