Expert-grade annotation infrastructure
The secure home for expert-grade data annotation.
11DATA connects AI teams with vetted, subject-matter-expert annotators for the high-value training data that fine-tuning and RLHF actually need — with quality review, secure client isolation, and automated payouts built in.
One platform
Three sides of the marketplace, one secure system.
For annotators
Do meaningful work, get paid fairly
Browse tasks matched to your skills, see the pay and time estimate before you claim, and build a reputation that unlocks higher-value expert projects.
- →Transparent pay per task
- →Skill-matched task feed
- →Weekly automated payouts
For clients
Ship better training data
Upload a dataset, choose a task type, and watch quality-reviewed annotations come back — with your data isolated and never exposed to other clients.
- →Text, image, audio & RLHF
- →Live progress dashboards
- →Expert or volume annotators
For our ops team
Run quality at scale
One console for the annotator pool, QA review queues, payout runs, and analytics — so throughput never comes at the cost of quality.
- →QA sampling & consensus
- →Reputation scoring
- →Audit trail on every action
The differentiator
Not just more labels — the right expert for the task.
Fine-tuning frontier models needs graduate-level judgement, not just volume. 11DATA vets annotators through credential review and qualification tests, then gates specialised, higher-paying projects to a verified expert tier — while a general pool keeps volume work flowing.
How it works
Simple for both sides.
Clients
- 1
Create a project
Pick a modality and task template — ranking, classification, bounding box, transcription.
- 2
Upload your data
Datasets stay encrypted and isolated. Annotators only ever see a single task-scoped slice.
- 3
Review & export
Track approved / in-review counts live, then export clean results as CSV, JSON, or COCO.
Annotators
- 1
Apply & qualify
Join the general pool, or upload credentials and pass a qualification test for the expert tier.
- 2
Claim & annotate
Work a skill-matched feed with pay and time shown up front. Claim, complete, submit.
- 3
Earn & level up
Quality feedback builds your reputation and unlocks higher-paying, specialised work.
Isolated by design
Each client's data is visible only to their team, assigned annotators, and ops — never another client.
Least-privilege access
Annotators receive a single task-scoped slice via short-lived signed URLs, never the raw dataset.
Audited & accountable
Every state change and payout is written to an append-only audit log for full traceability.
