What we do

Everything you need, in one place.

Three integrated services to unlock the full potential of your training pipeline

Data Collection

Capture the real world your AI needs — across people, environments, actions and scenarios, wherever the data lives.

  • Multi-camera capture up to 4K/60fps
  • Authentic environments. Real-world behavior.
  • Consent & compliance handled on-site

Data Annotation

Turn raw data into structured intelligence with precision annotation, domain-trained teams and multi-stage quality control.

  • Image, video, audio, text, 3D & document labeling
  • Multi-stage QA with measurable annotation consistency
  • Delivered in industry-standard, model-ready formats

AI Training Datasets

Purpose-built datasets engineered around your model, use case and scale — ready to integrate into your training pipeline.

  • Covers robotics, computer vision, speech & language
  • Ready-to-train exports in the formats you need
  • Full documentation on specs, consent & quality metrics

How we work

From brief to delivery in five steps.

One proven workflow, built to scale — from a focused pilot to a nationwide production program.

1

Specification

Model requirements translated into a capture or annotation spec — configuration, task scripts, diversity matrix, delivery format.

2

Protocol Design

Hardware setup, guidelines, participant/consent flows and QA checklists built before execution starts.

3

Execution

Domain-trained operators and annotators run the program, with daily progress reports and sample batches for review.

4

QA Review

Multi-stage review by domain-trained QA engineers — consistency, quality, diversity and compliance.

5

Delivery

Dataset delivered in your preferred format, with documentation covering specs, consent and quality metrics.

Need only part of the process? Every stage above can stand alone — from workforce and location sourcing to production and final QA — KOS slots into wherever you need extra capacity, full pipeline or a single service.
Proof of execution

Proof from KOS's own track record.
