For global AI teams

Southeast Asian data for labs and data vendors in the US, Europe and beyond.

Your models are reaching nearly 700 million people in Southeast Asia. We supply the native-speaker judgment and real-world footage that is hard to source from outside the region, as a managed team with one contract and one point of contact.

Expert language work

Native Malay, Indonesian and Malaysian Mandarin speakers for model evaluation, red-teaming, safety review, preference ranking and response writing, trained on your guidelines and measured on agreement.

Real trade-work footage

First-person and fixed-camera video of skilled construction, waterproofing and repair work from working crews, with written consent from workers and site owners, for robotics and physical-AI teams.

Licensed datasets and capacity

Licences to consented speech, defect and site collections, and overflow annotation capacity for data vendors that need Southeast Asian languages handled by a vetted team.

All prices in USD. Contracts in English, invoiced from Malaysia. Ask for our global rate card.

How a pilot works

See the quality on your own data before you commit.

  1. Scope

    Send a sample of your data and what the model needs to learn. We draft labelling guidelines with you.

  2. Calibrate

    We label a small set together with your team and settle every edge case in the guidelines.

  3. Pilot batch

    We label a fixed batch at production settings and deliver it in your format.

  4. Quality report

    You get agreement scores, error examples and a price per item for the full volume.

Quality and data handling

Every batch is measured, not assumed.

Your data stays in the scope you set, and you see the numbers behind each delivery.

  • Double annotation on a sampleTwo annotators label the same items so agreement can be scored and disagreements reviewed.

  • Gold-set checksKnown answers are mixed into every batch to catch drift early.

  • Guidelines you ownEvery rule and edge-case decision is written down and handed over with the data.

  • Handled under Malaysia's PDPANDAs as standard, access limited to the assigned team, and personal data redacted where the task allows.
