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.
AI data extraction from PDF financial statements and complex documents.
Pull structured figures out of balance sheets, income statements and cash flow statements with accounting-grade accuracy.
Capture data from bank statements, invoices, contracts, trade finance documents and identity documents like passports and driving licences.
Point-and-click to define the data points you want; no rule writing or coding required.
Users correct errors and the system learns, so accuracy improves on your specific document styles over time.
