High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
Discover proven startup ideas and adapt them to your market
Search by industry, target user group or Jobs-To-Be-Done so results line up with how you actually think about opportunities.
Flag ideas that are funded and proven elsewhere but not yet established in your own country, which is the core use case.
Every idea is tied to startups that raised real money, so you are exploring concepts with evidence of market interest.
Filters for launch date, customer type, business model, funding status, region and required skills narrow thousands of entries to a shortlist.
