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.
Expert-led, AI-native primary research for private equity, healthcare and life sciences — consulting-grade studies delivered in about two weeks.
A senior researcher owns the study from kickoff to readout, scoping the business decision, audience, method and deliverables.
AI interviewing agents run conversations at scale across multiple languages, with eight checks on every interview and live coding.
Combine qualitative depth with quantitative rigor — including Van Westendorp pricing and choice-based conjoint — in one conversation.
Get an executive report with a research appendix, the underlying data, and a live readout, typically within about two weeks.
