AI agents that run document-heavy business processes end to end
Agents read invoices, POs, remittances, claims and forms, then act on them — matching, approving and posting rather than only extracting fields.
Clean, validated data is written directly into systems of record including SAP, Salesforce, NetSuite, QuickBooks and Gmail workflows.
Policies, SOPs, system data and conversation history are stored as a governed graph so every agent decision cites the rule and document behind it.
Prebuilt flows for accounts payable, reconciliation, order management, cash application, supplier onboarding and claims processing.
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.
