Our solution

The GreyCat Technology

GreyCat emerges after several years of research to efficiently analyze large-scale data in live. It is designed as a toolset to develop customized operational decision-making tools, able to run on big data centers but also on commodity hardware. Upon several years of successful cooperation at the University of Luxembourg, the co-founders of DataThings and creators of the GreyCat framework decided that it is time for the next chapter: GreyCat Enterprise.

Digital Twin & Simulation

Create Digital Twins of your production tools by learning their behavior from their historical data, to produce prediction and simulation engines which accuracy outruns theoretical models by taking into account all your business' specificity.

Continuous learning

Models can be trained continuously to reflect the most recent evolution of your business, and take into account the impacts of seasonality, markets trends, shifts, etc. so their predictions are always up-to-date. And by the way, learning this way is cheaper than learning by huge batches.

Big Data on reasonable hardware

Give a try to machine learning and data analytics with GreyCat without investing in a huge infrastructure. We made sure that learning can run on commodity hardware, leveraging a great team work between storage disks and RAM. Then, if you want to scale, GreyCat will make the best of the resources at its disposal to accelerate the data processing.

Analytics And Machine Learning

GreyCat provides state-of-the-art machine learning algorithms, like neural networks and Gaussian mixture models, specifically adapted to take advantage of its temporal graph and empower your businesses with insights refined from your data.


GreyCat can be embedded in applications, deployed on a server on premises, embedded on edge computing platforms, or run in the cloud; you decide what suits you best.


As former researchers, we continuously look at the most advanced methods to solve your challenges. We keep a very strong connection to research institutions around the world.
