Capabilities · 01–04

Expertise tailored to the modern LLM lifecycle.

We provide the ground-truth data and human evaluation that take AI initiatives from prototype to global-scale production.

01

AI Data Annotation

High-fidelity labeling for complex linguistic structures — entities, intent, and cultural nuance — across 140+ languages.

02

Audio & Accent Training

Phonetic calibration and native-voice datasets so speech models truly understand regional dialects and sociolects.

03

Prompt Evaluation

Expert ranking, adversarial testing, and safety review of model responses by trained linguistic reviewers.

04

Content Creation & Rating

Human-led RLHF datasets and localized ground truth for validation, tuning, and benchmarking.

…and many other critical LLM development tasks. Every engagement is scoped to your architecture and evaluation needs.

Global reach

Global coverage is our default.

Our network spans six continents, providing real-time cultural context that automated translation tools miss. We don't just translate — we localize intent.

Hi
Our method

Precision as a deliverable.

01

Native expertise

Linguists and subject-matter experts, not generic labelers. Every task is done in-language, in-culture.

02

Triple-blind QA

Every data point verified through independent review. Precision compounds at scale.

03

Adaptive scaling

From niche dialect studies to global rollouts, ops flex to your velocity without diluting quality.

Let's take your AI to the next level.

Whether you're launching a new AI product or scaling existing operations, our solutions are tailored to your specific needs.
