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.
Governed agentic and embedded analytics on your own data warehouse
AI drafts metric definitions from your warehouse, you approve them, and every dashboard, embed and agent answer resolves to one signed-off definition.
Ship customer-facing dashboards styled with your design tokens, in light or dark mode, with scheduled reports sent from your own subdomain.
Row-level and column-level rules plus role-scoped guest tokens are enforced before any SQL runs, so an embed can never show more than it allows.
An agent builds charts and edits dashboards from prompts, while an MCP server exposes the governed model to Claude Code, Cursor, Codex or Windsurf.
