Data Sphere Lab

For fast-moving ML teams, the biggest bottleneck isn't training models—it's sourcing clean, accurate, and reliable training data. We solve this. We provide quality-first visual data annotation designed to eliminate iteration loops and accelerate your path to production. Our human-in-the-loop process guarantees precision at scale. We don’t just run your data through a model. Every label is placed, reviewed, and validated by expert annotators who understand your data’s context. To ensure the highest standards of quality and security, all annotation is performed by our specialist team in Poland and is never outsourced. This methodology, backed by a research partnership with AGH University of Science and Technology, applies scientific rigor to every dataset we deliver. We adapt to your project at every step. Whether you need data tomorrow or next month, we scale our team to meet your timeline. Your data stays yours, protected by secure, access-controlled workflows built to meet your requirements. Our Core Areas of Expertise: To deliver the highest quality, we cultivate deep domain knowledge. We specialize in providing context-aware data for leaders in: Automotive: Supporting the development of ADAS and autonomous systems with precise 2D, 3D, and LIDAR annotation. Medtech: Annotating medical imagery with anatomical precision for diagnostic and research applications. Industrial & Manufacturing: Labeling machinery, defects, and production flows to automate visual inspection. Don't see your industry?
