Our mission

When humans perform tasks and solve problems, they rely heavily on their common sense knowledge about the world. A detailed understanding of the physical world is however still largely missing from current applications in artificial intelligence and robotics. Our mission is to change that. We are developing new, ground-breaking technology that allows machines to perceive the world like humans.

How it works

Our technology can analyze human actions and extract real-time information from video streams. We build deep learning systems using our large video datasets about common world situations and then fine-tune them to specific use cases with minimal effort.

A novel database

One of the limiting factors for advancing video understanding is the lack of large and diverse real-world video datasets. To circumvent this bottleneck, we have built a scalable crowd-acting™ platform and have created some of the largest industry video datasets for training deep neural networks.

A unique approach

Our deep neural networks are pre-trained on our datasets of crowd-acted videos. The datasets contain short video clips that show a wide range of physical and human actions. We then transfer the capabilities of our trained network to contribute to specific video applications.


Step one

We pre-train deep neural networks on a foundational dataset for understanding physical actions. A large amount of annotated video data is required so that the models develop an internal representation of how objects interact in the real world.


Step two

We transfer this intrinsic knowledge to solve problems of high complexity that rely on an understanding of these fundamental physical concepts. The data requirements are drastically lower, allowing us to solve a large variety of video use cases.
