Overview
The Human Data Behind Better Models
Graveiens AI delivers the high-quality human data that AI teams need — annotation and labelling, end-to-end data collection, RLHF/SFT human feedback, consent-backed multilingual voice and speech data, transcription and LLM evaluation. We bring a trained workforce and STEM subject-matter experts, not just crowd labels.
Our education roots give us a rare bench of pedagogically-trained SMEs for STEM validation and domain data, and our voice programs are built with explicit consent end to end. You start with a pilot billed only on approved deliverables.
