Agentic skills intelligence for hiring, developing, and planning talent
Technical, business, agentic, behavioral, and diagnostic evaluations built around real job tasks.
Structured conversational interviews that give teams clear skills evidence early in the funnel.
A shared workspace where candidates solve real problems while interviewers observe how they work.
See where your workforce is strong, spot gaps early, and plan hiring, mobility, and redeployment.
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.
