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.
Measure engineering work and AI's real contribution to it.
Brings AI metrics, DORA and SPACE-based benchmarks and developer feedback into one view so you can see where work stalls from prompt to production.
Relates AI-assisted usage to merges, quality and cost, with per-engineer AI usage and AI score reporting plus benchmarks against 1,000+ organisations.
Connects token and prompt spend to engineering output so you can see what you are getting for every AI dollar spent.
Weave Router classifies each prompt and routes it to the model with the best quality-per-token, learning from team feedback over time.
