How teams put our data services to work

Representative scenarios across voice, annotation, RLHF and evaluation. Details are anonymized; the capabilities are real.

Voice AI

Multilingual, consent-backed speech at scale

Challenge. A voice-AI company needed large volumes of consent-backed speech across several Indic and European languages, with tight quality and compliance requirements.

What we did. We ran the full pipeline — artist onboarding with explicit consent, managed recording, metadata tagging and QA — delivering accent-tuned, labelled audio.

Outcome. The team received a compliant, auditable dataset ready for ASR training, and scaled more languages on the same pay-on-approval terms.

Medical LLM

Expert evaluation for a safety-critical model

Challenge. An enterprise fine-tuning a medical LLM needed qualified reviewers to judge accuracy and safety.

What we did. Our medical SME bench scored responses against a strict rubric and wrote reference answers, improving the signal in the preference data.

Outcome. Cleaner alignment data and defensible, expert-backed evaluation to support release decisions.

Computer vision

Pixel-accurate annotation on a large image and LiDAR set

Challenge. A perception team needed consistent, high-accuracy labels across a large multi-sensor dataset.

What we did. We adapted tooling to their ontology and scaled 2D and 3D annotation behind gold-standard checks and four-stage review.

Outcome. Consistent labels at volume and a maintained post-QA accuracy bar, delivered on approved-only billing.

FAQ

Questions, answered

Can you share named client references?
We keep client work confidential and present anonymized scenarios. In a conversation we can talk through relevant experience for your use case.
Can we start with a small test?
Yes. Most engagements begin with a pilot batch billed only on approved deliverables, so you can validate quality before scaling.
Which data types do you cover?
Text, image, video, audio and 3D/LiDAR — from collection and annotation to transcription, RLHF and evaluation.
