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.
On-device behavioral intelligence that turns phone sensor data into driving, mobility and lifestyle insights
Machine learning models run locally on the smartphone, so insights are produced in real time without shipping raw sensor data to the cloud.
Detects vehicle crashes on the device and generates a report with time, location, severity indicators and surrounding driving events.
Produces trip-level and user-level scores plus segment profiles such as aggressive, anticipative or legal driver for risk pricing and claims workflows.
Identifies transport modes, trip purposes, eco scores, venue types, routines and physical activity levels to build complete user context.
