DNA-powered personalized fitness, nutrition and recovery
A saliva DNA test maps genetics related to fitness response, nutrition and recovery, producing an actionable blueprint rather than a raw report.
Connects wearable sensor data to track activity, sleep and daily readiness, feeding those signals back into your weekly plan.
Your exercise, nutrition and recovery plan is rebuilt each week from your goals and latest biometric data so it never goes stale.
Choose a focus such as losing weight, building strength, increasing longevity or supporting GLP-1 treatment, and the plan adjusts accordingly.
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.
