What is a synthetic buyer?
A synthetic buyer is a simulated buyer built from real public language about a market, not an invented persona. It is reconstructed from thousands of things real buyers said in reviews, forums, and public discussion, so it reacts to marketing the way a real buyer in that market would. Provv uses synthetic buyers to test copy before it ships.
Built from real language, not invented from a prompt
A synthetic buyer is reconstructed from public quotes about a market: reviews, forum threads, comparison content, podcast transcripts, public discussion. The patterns are already in the data. The buyer is the cluster of language that keeps showing up, rebuilt in its own words. That is what makes it react the way a real buyer in that market would, and what lets it push back instead of flatter.
Why it is not a persona
A persona is a guess written by a marketer. A synthetic buyer is grounded in evidence you can read. Every claim a synthetic buyer makes about itself traces back to source quotes you can open and check. That is the difference between an opinion in a slide and a reaction with receipts.
What you use one for
A fast, directional read on marketing copy before you ship it, for the moment when commissioning real research is too slow or too expensive. Use it on the headline, the cold email, the ad, the pricing line, the launch narrative. It does not replace talking to real customers. It gets you to that conversation sharper, and it catches the obvious losses before they ever cost spend.
