Quality benefits from advanced

Our mission is to provide training and validation data to increase the accuracy of autonomous driving algorithms for mobility companies.

Launched in 2016, founders Marc Mengler and Philip Kessler recognized the importance of accuracy in annotated data for self-driving vehicles to intelligently perceive the road ahead. With the vision to keep passengers and pedestrians safe, they focused on contributing to the qualitative perception of self-driving cars.

With the combination of machine learning algorithms and human intelligence their idea quickly formed into a fast growing start-up. We have grown to a team of more than 40 exceptional individuals, with three office locations and managed projects with more than 100 million annotated images. But, this is just the beginning. For our customers to succeed, billions of images must be annotated to precisely train and validate autonomous driving models.

Our team consists of diverse individuals with wide-ranging talents – the majority are engineers with relevant expertise previously working at companies including BMW, Bosch, Google and Mercedes-Benz.

The passion behind it

Driven by our mission we create the foundation of data for the development of safe algorithms.


Philip Kessler Co-founder & CTO

Philip’s commitment to enabling the future of autonomous driving began with developing an autonomous driving model car with the student group KITcar. During his studies in computer science at the Karlsruhe Institute of Technology (KIT), Philip deepened his passion with an internship in the machine learning and data science department at Mercedes Benz in Silicon Valley. There he worked in a highly international pre-development team building early prototypes to showcase new technologies. Philip is a regional director of The Kairos Society, a global community of young entrepreneurs.

Marc Mengler Co-founder & CEO

Coming from an entrepreneurial family, Marc Mengler obtained a Master in Entrepreneurship & SME Management and a second Master in Data Science and Machine Learning to combine his passion for startups and deep tech research. During his academic research, he analyzed the impact of high-quality data on the robustness of state-of-the-art neural networks. This lead to the founding of understand.ai with the goal to build a scalable services model, based on a repeatable quality process and advanced technologies, for efficiently creating accurate training and validation data. On a personal level, Marc has been honored to have played chess against three world champions.

We work worldwide

Our headquarters is in Karlsruhe, Germany. It was named center of artificial intelligence in Germany, home to one of the leading European IT universities and industry-leading research centers like FZI and Fraunhofer. To stay connected with customers and other centers of AI expertise, we are also in Berlin and San Francisco.
