The Comparison
Real panels vs. simulated markets.
The Panel Problem
Real participants are unpredictable.
The Bot Epidemic
Prolific has a reputation for quality, but even they battle bot infiltration, attention check failures, and speeders. You spend hours cleaning data before you can analyze it. Simulated personas don't bot.
The Quota Wait
Need 200 'C-level executives at Series B startups'? That quota might take days to fill — if it fills at all. Niche audiences on real panels are scarce and expensive. TestSynthia's niche personas are always ready.
The Hidden Fees
Prolific charges $1-3 per response plus 33% platform fees. A 500-response study costs $665-1,995. And that's before you factor in data cleaning time. TestSynthia: 500 responses for $79. Flat.

Choose Prolific If...
You need real human responses for academic publication, behavioral economics, or final investor validation. Real data has credibility that simulation can't fully match.
Choose TestSynthia If...
You need fast, affordable, consistent responses for concept validation, pricing, and messaging. You're running frequent studies and can't afford panel costs or wait times.
