Every AI product is built on training data. The quality of your data determines the quality of your model.
Four annotation service lines. One consistent quality standard. A QA report on every delivery.
COMPUTER VISION
Annotation for AI that needs to see the world accurately.
Precision is non-negotiable when your models interact with the physical world. From autonomous vehicles to safety to medical imaging diagnostic support, we provide pixel-perfect labels across diverse sensor data and environments.

TEXT & NLP ANNOTATION
Language models learn from labelled text. The labels have to be right.
Raw text contains the complexity of human intent, nuance, and regional variance. Our linguist-led teams ensure your datasets capture the subtle meaning behind the words, providing the ground truth for state-of-the-art NLP models.

LLM TRAINING DATA
A capable base model becomes a useful product through human feedback.
We provide the critical human feedback loop (RLHF) required to align large language models with human values, safety guidelines, and specific brand voices. Our specialised agents act as the "ideal user" for your foundation models.
What we annotate
RLHF Response Ranking
Human annotations rank multiple model outputs based on helpfulness, honesty, and harmlessness.
Instruction Quality Rating
Evaluating the model's ability to follow complex, multi-step instructions and constraints.
Preference Pair Labelling
Generating direct comparison labels to train reward models for reinforcement learning.
Harm & Safety Flagging
Identifying toxic, biased, or dangerous content to ensure robust safety guardrails.
WHAT IT COSTS
Transparent tiers. No surprise invoices.
Scalable pricing designed for every stage of development: from early R&D to enterprise-scale production deployments.

Frequently Asked Questions
Everything you need to know about our data labelling operations and quality standards.
QUALITY & PROCESS
What is your typical accuracy rate? ⌃
We maintain a guaranteed 99% accuracy rate through our three-stage verification process: inter-labeller peer review, QA lead inspection, and a free accommodating QA audit on every batch.
How do you handle edge cases? ⌃
Edge cases are escalated to our QA lead and documented in the quality report we deliver with every batch. Ambiguous instances are flagged and resolved with the client before we proceed.
SECURITY & COMPLIANCE
Is my data encrypted? ⌃
Yes. All data in transit uses TLS 1.3. Data at rest is AES-256 encrypted. We operate in a biometric-secured, air-gapped facility in Lagos.
Are your workers HIPAA compliant? ⌃
Yes. Annotators are trained in HIPAA data handling. We sign BAAs for all medical imaging projects and can produce compliance documentation on request.
