greifen was started with a simple observation: humanoid robots are advancing rapidly, but the data needed to train them is becoming the primary bottleneck — not the hardware.
The word greifen is German for "to grasp" or "to reach" — the most fundamental manipulation skill any physical agent needs to learn. It describes both what we capture and what we enable.
We build egocentric motion datasets from real European environments: German households, workshops, warehouses, and care facilities. We annotate them with 21 hand keypoints in 3D, natural language descriptions, and action labels — and deliver them in formats that drop directly into modern Physical AI training pipelines.
Our pipeline is fully local. No cloud annotation services, no third-party data brokers. Every dataset is GDPR-compliant from capture to delivery — with full consent documentation and data lineage records.
greifen is based in Neu-Isenburg, Germany. We work with robotics companies, research institutes, and automotive OEMs across Europe as an equal partner — from scoping to delivery. Reach us at hello@greifen.tech
