Graveiens began as an education-outsourcing company, building content, assessments, multimedia and accessibility work at scale for publishers, EdTech companies and institutions. That work demanded exactly what good AI data demands: subject-matter depth, multilingual reach, and quality processes that hold up at volume. Graveiens AI is the natural next step — applying our expert network and QA discipline to data collection, annotation, voice data and model feedback for the AI industry.
See how we workWe believe the hardest problems in AI data are human ones — judgment, language, edge cases and consent. So we lead with people: a vetted network of subject-matter experts, linguists and trained specialists, supported by tooling adapted to each client, and wrapped in an ISO 9001:2017 quality workflow.
