Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
Automated recruiting conversations and AI interviews for high-volume, frontline hiring
Outreach across chat, SMS, email, voice and video so every applicant receives a timely reply, with automatic re-engagement of past applicants.
Structured AI-run video, voice and asynchronous interviews delivered consistently to every candidate, with ranked output for recruiters.
Candidates are evaluated through structured conversations rather than keyword resume matching, producing a ranked shortlist with the transcripts and reasoning behind each name.
Configurable workflows evaluate, score and book qualified candidates into interview slots automatically, so top applicants get invites before competitors respond.
