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.
Engineering analytics that turn delivery data into better software decisions
Out-of-the-box dashboards for DORA metrics, cycle time, throughput and software quality, built from data pulled automatically out of your existing toolchain.
Ask natural-language questions about team performance, delivery gaps and metric movements, and get answers derived from your own engineering data.
Forecast the completion of initiatives, epics and releases from historical delivery data, then track progress against measurable engineering goals.
Jira, GitHub, CI/CD systems and PagerDuty are supported out of the box, with custom integrations available so no part of the pipeline is invisible.
