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.
AI agents that automate high-stakes logistics and customs work
Agents ingest invoices, packing lists, bills of lading, and forms in any format, pulling out the exact fields your downstream systems expect.
Use native connectors for common logistics and accounting systems, or build custom integrations into your own internal software and databases.
Shipment consolidation, quoting, accounts payable, customs preparation, and duty drawback templates get you live in weeks rather than months.
Upload your existing procedures and context so agents follow how your operation actually runs, and improve as they see more documents.
