Today, optimizing conversions is done using simplistic methods like A/B testing.
We handle the complete package of personalization with an easy-to-integrate API HTTP layer.

Example use case: Personalized UX for mobile store

Conventional approaches

Conventional approaches are iterative by design. Therefore, experiments can only adapt to environmental situations that lie in the past, and become outdated very fast.

Features of stores are usually optimized in isolation, without regards to the bigger impact on the customer lifecycle. While this simplifies the algorithmic challenge, it also severly limits the total achievable uplift.

Conventional methods have a significant need for manual intervention. They usually demand a constant creation of hypotheses, checking of segments for consistency and interfacing with IT for implementation.

Explored uplifts suffer from a significant delay between findings and their exploitation. In dynamic environments, that can even lead to vanishing uplifts.

Conventional Machine Learning is heavily dependent on the quality of a process called feature engineering. This approach is very expensive, error prone and not robust to changes in the environment.

Many classical Machines Learning algorithms are not easily scalable. That leads to severe problems as the data set grows.

Free Machines

By fundamental design, our algorithmic core is able to continuously adapt to new situations. Designed as an end-to-end decision system, it is built to be deeply integrated into production systems and therefore can instantly react to changes in the data.

Instead of focusing on single features, our algorithm enables a sustainable optimization of the whole customer lifecycle. This can include the long-term goals that actually matter to your business.

After the simulation period, where the system learns behavioural structures of your business and your customers, the systems constantly moves towards a very high degree of automation. With extensive monitoring capabilities, we allow you to focus on the big picture.

The system continuously learns and is able to exploit these findings in real-time. You'll never again will have to wait for the next optimization iteration.

free machines is built upon state-of-the-art Deep Learning approaches. Manual feature engineering is replaced by deep network architectures that learn the optimal feature set automatically.

Our algorithmic core is built on highly scalable tensor arithmetic, it is extremely scalable on GPUs. Data access is handled by a redundant, high-availablility web interface. Therefore, we are capable to handle very large datasets.


That sounds great, we hear you say, but how does it drive conversions?

Performant APIs

Nobody likes waiting for a shop to load, that's why we're focussed on speed & stability. Enjoy lightning speed with the Free Machines API.

Privacy first

We are the only personalization solution on the market that was designed from the very start to be GDPR compliant. Thanks to special encryption, the data we work on is fully anonymous.

Artificial Intelligence

Our technology is based on Deep Reinforcement Learning to ensure that your users find the content that is relevant to them in the shortest amount of time.
