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 like a real buyer in that market would.
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, which is why it can push back on copy instead of flattering it.
What you use one for
You use a synthetic buyer to get a fast, directional read on marketing copy before you ship it, when commissioning real research is too slow or too expensive. It does not replace talking to real customers. It gets you to that conversation sharper.
