Annotation that scales — accurate, auditable, and SLA backed.
We combine skilled human reviewers with automated tooling to deliver high quality labeled data for computer vision, NLP, audio, LiDAR and multimodal ML workflows — at scale and with guaranteed SLAs.
What we deliver
Our Human-in-the-Loop annotation services ensure your ML models are trained on the highest quality data:
- High accuracy via multi-pass HITL workflows (annotate → review → QA → adjudicate)
- Flexible scale: from pilot batches to continuous pipelines supporting hundreds of thousands of items/month
- Security & compliance: role-based access, encrypted data transfer, and ISO-grade controls for sensitive projects

Our Advantages
Understand how our data collection approach improves model quality, compliance, and time-to-market.
Optimized for quality
We have a two-layer QC process that ensures the quality of the output. This is enabled by a short feedback loop process.
End to end solutions
From data collection and cleaning to data annotation, we offer End to end solutions for your training data needs.
Cost efficient
Our pricing is transparent and economical. We are more cost-effective than contract workers and large annotation platforms.
Completely managed
Our services are fully managed with dedicated account managers to ensure smooth operations.
Scalable workforce
Start with a single person and grow with us. We scale our team based on your demands.
Data security
Data security is paramount. We are GDPR compliant and ISO 27001 certified.
Industries we serve
Purpose built AI data services for the workflows, challenges, and scale unique to your industry.
Build a production grade HITL pipeline
Get high-quality labeled data at scale with our Human-in-the-Loop annotation services. From pilot projects to production-scale pipelines, we deliver accurate annotations with guaranteed SLAs.
