Introducing RealSynth

The Virtual Gym
for your AI

We create virtual Worlds to safely train and test
autonomous systems.
Learn More

RealSynth is a start-up company based in Berlin, Germany. We are backed by TechStars and next47 (the independent investment arm of Siemens).


Our Mission

We Streamline AI Development

Collecting and annotating training data for autonomous systems is a very costly and labor intensive process. Moreover, those systems need to be tested and verified rigorously under a huge variety of scenarios and conditions before they can safely be deployed in the field.

We at RealSynth aim at minimizing the need of field data and field tests. We build fully tagged, realistic virtual environments to train and test AI faster, cheaper, and safer than the current manual process.

Our Product

What RealSynth stands for


Our synthetic environments and sensor models are designed for highest technically possible fidelity.


We emphasize seamless integration to existing development workflows through a cloud interface.


Run just a single, or hundreds of sessions in parallel. Drive billions of virtual test kilometers at the push of a button.


We support common data formats (KITTI, COCO, VOC) and interface with standard middleware solutions, such as ROS.

Edge Cases

Push your algorithms to the limit and repeat critical, yet seldom edge cases over and over.


Control a large variety of parameters including sensor parameters (such as sensor/lens settings), lighting conditions, weather conditions, and scenarios.

Our Technology

RealSynth Under the Hood

A highly customized version of the Unreal Engine 4 enables fully automated capturing of ground truth data, rendering scenarios at different times of day, and various weather conditions in real-time.

Our technology allows providing enormous quantities of annotated image data fast, fully customized and at low costs.

Beyond that, our proprietary simulation environment is optimized for low latency, scalable cloud deployment.

Proof of Concept

Jul 15, 2017 - Dec 15, 2017

In our first paid pilot project with a large corporate, we were able to show that blending our synthetic data with an existing real dataset can improve object detection performance significantly.


Jul 9, 2017 - Oct 5, 2017

We successfully graduated from the TechStarts Internet of Things startup accelerator program in New York City.


Jun 27, 2017

RealSynth GmbH was founded as a spin-off from Siemens Mobility Technology & Innovation.
