Pay real, targeted respondents. Sampul filters out the garbage before it hits your data.
Build
Drag in questions, set what you'll pay per response, and publish. Add attention checks and screeners so only the right people get through.
Quality
Targeted people actually answer — and built-in fraud checks quietly reject the garbage before it ever reaches your dataset.
Earn
Respondents browse forms they qualify for and get paid per response — right from their phone. That's what keeps real people answering.

New · Build with AI
Connect Claude (and other MCP-compatible tools) to Sampul. Describe what you want to learn — it writes the questions, sets the targeting, and suggests a fair payout, building a ready-to-review draft on your account. You just check it and hit publish.
“Survey on how Lagos students pick a bank — 6 questions, target 18–24 in Lagos.” That's the whole brief.
Questions, targeting, and a recommended payout — assembled on your account in seconds, not an afternoon.
The AI can never move money. Publishing and payment always happen here, by you, on Sampul.
