Annotation pipelines built for foundation-model SLAs.
Speech, NLP, CV and multimodal annotation at IAA ≥ 0.85 with two-pass QA — built for foundation-model SLAs.
Speech, NLP, computer-vision and multimodal labeling with a measured quality bar, two-pass QA and adjudication — across the languages and domains generic annotation crowds can't credibly cover.

Annotation quality is where most data programs quietly fail. A generic crowd can't disambiguate honorifics, code-mix, regional idioms or domain-specific entities — and without measured agreement, you can't tell good labels from confident guesses until the model regresses.
Scaling without losing the quality bar is the hard part: guidelines drift, edge cases pile up, and inter-annotator agreement slips just as volume ramps.
Consistent, measured ground truth: calibrated guidelines, specialist annotators, two-pass QA with adjudication, and inter-annotator agreement reported per batch. Versioned deliveries with audit logs and a data card — labels you can stand behind.

-
India-residency capable
Collection, annotation, processing and storage available in-country, aligned with the DPDP Act, 2023.
Sovereign delivery -
Documented & measured
Published quality metrics, provenance and license terms on every delivery — transparency technical buyers can audit.
FAQ
Data Annotation — common questions
- Is the data rights-cleared and safe to use commercially?
Yes. Every record is created or sourced under written agreements granting commercial reuse, with a consent reference and authorship log attached. We don't ship scraped data you can't legally train on.
- How do you measure and report quality?
We publish quality metrics on every delivery — inter-annotator agreement, QA pass rate, and (for speech) word error rate — with two-pass QA and adjudication. Each drop ships with a data card documenting methodology and provenance.
- Can you guarantee India data residency?
Yes. We offer sovereign delivery: work performed and stored entirely within India, aligned with the DPDP Act, 2023. See our Sovereign Data page for the full residency and compliance posture.
