Value proposition
Deliver high-quality expert human data, RL environments, and contextual evaluations at scale so frontier AI labs can train and improve models and agents faster than commodity labeling.
Products and solutions
Talent: A service to hire world-class engineers for core teams., Zara: An AI recruiter that sources, screens, and interviews candidates., gpt-vetting: An AI-powered tool for conducting technical interviews.
Unique value
Combines AI-powered expert vetting with a global domain-expert network and new RL/eval/robotics products (Realm, Cortex, Robotics) to supply high-skill human data that commodity labeling platforms struggle to match.
Target customer
Frontier AI labs and enterprises needing expert human data, evaluations, and robotics/embodied training datasets.
Industries served
Artificial Intelligence, Foundation Model Training, Robotics, Legal, Healthcare, Finance
Technology advantage
AI interviewing/vetting at massive scale to onboard top-percentile domain experts, plus integrated workflow/QA/payroll for RLHF and new RL-environment (Realm) and robotics data products—full-stack human-data delivery to labs.
How they differentiate
Focuses on high-skill domain experts (vs low-skill commodity labeling), AI-vetted at scale, plus RL environments and robotics data capture; positioned as a Scale/Mercor/Surge peer for frontier-lab human data rather than a pure staffing marketplace.
