What we do

Capabilities under this practice

Each capability runs to a defined delivery contract — scope, KPIs, reporting cadence and exit criteria are fixed up front.

LLM & multimodal annotation

RLHF, preference data, instruction tuning, conversational QA, factuality and safety annotation across 12+ languages.

Computer vision labeling

Bounding boxes, polygons, semantic & instance segmentation, keypoints, 3D cuboids and LiDAR / point-cloud labeling.

Model evaluation & red-teaming

Structured eval rubrics, blind A/B comparison, adversarial probing and safety / bias audits aligned to your policy.

Domain expert workforce

On-demand access to MDs, JDs, PhDs, native bilinguals and licensed engineers — vetted for high-stakes labeling.

How we work

A clear path from kickoff to scale.

No mystery work-streams. Each engagement runs through the same four phases — adapted to your scope, but never invented from scratch.

  1. 01

    Calibration

    We co-design annotation guidelines, golden sets and inter-rater agreement targets before labeling begins.

  2. 02

    Pilot batch

    A small batch is delivered within 72 hours so you can validate quality and unblock guideline ambiguities.

  3. 03

    Scaled production

    Tiered review (annotator → reviewer → audit) with live dashboards on throughput, agreement and SLA adherence.

  4. 04

    Continuous improvement

    Weekly error analysis is fed back into guidelines and golden sets — quality compounds over the program lifetime.

FAQ

Questions clients usually ask first.

Can you work in our annotation tool?

Yes. We work in Label Studio, CVAT, Scale Studio, V7 and customer-specific tooling, or provide our own platform when useful.

How is data security handled?

Per-program controlled environments, signed NDAs at the worker level, configurable PII redaction, and on-prem / VPC delivery for sensitive datasets.

Do you support multilingual content?

Yes — strongest coverage across English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Bahasa, Vietnamese, Thai, Tagalog, Hindi, Spanish and Portuguese.
