A quick look at how Graveiens AI partners with teams to deliver human data for AI models.
Graveiens AI 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.

A world where advanced AI is built on data that is accurate, consent-backed and inclusive — where quality and ethics scale together, not in tension.
A combination of things you rarely find in one partner.
A STEM and domain SME bench inherited from our education business — experts who can judge correctness, not just fluency.
Explicit-consent onboarding, metadata tagging and audit trails on every voice and data program.
Deep Indic coverage alongside major Asian and European languages, with native review.
A four-stage workflow — create, internal review, client review and rework — measured against gold standards.

A 700+ expert network you can flex from a single pilot to an ongoing program.
Graveiens AI is a network of vetted specialists, organised into teams around the skills our clients need. Rather than a single crowd, you get the right people for the task.
STEM, medical, legal and finance specialists for validation, LLM training and grading.
Native speakers across 25+ languages for translation, transcription and voice data.
Trained annotators and reviewers across image, video, 3D, text and audio.
Python, TensorFlow, PyTorch and NLP specialists for pipelines, tooling and fine-tuning.
Single points of accountability who manage scope, quality and turnaround.
Teams that vet contributors, manage consent and keep data handling compliant.
Graveiens AI grew out of an established education-services group that has delivered content and learning solutions to publishers and EdTech leaders since 2017. That heritage gives us something most data vendors lack: a deep bench of STEM, medical, legal and finance subject-matter experts who can handle the judgement-heavy work behind modern AI — from expert LLM evaluation to specialist annotation.
Today that expertise powers consent-backed voice data, high-accuracy annotation and human feedback for AI teams worldwide, delivered with enterprise-grade quality and terms designed to de-risk working with us.
