Our Mission

Enable latest AI technology for our partners in industry and clinical research

Outside the university, research projects are often tied to the goodwill and innovative strength of entrepreneurs and decision-makers. A major obstacle can also be the proper setup of a suitable project infrastructure. Especially in the field of AI research, large computing capacities and solid data management are of utmost importance.

Our mission is to make Machine Learning and Deep Learning usable not only for companies, but also for research projects.

For this purpose, we offer our longterm project expertise as well as the necessary hardware and software.

Because we believe that innovations are created by supporting the advance of AI research projects that contribute to healthcare, economy, and society.

We are specialists in the development of innovative AI solutions for medical image processing and machine learning applications.

History

The idea for Chimaera was born during the PhD studies of the co-founders Dr. Marcus Prümmer, Dr. Dieter Hahn and Dr. Volker Daum together with their mentor and advisor Prof. Dr. Joachim Hornegger. Based on their longtearm experience in machine learning research, they recognized the challenges of developing the right software tools and services for artificial intelligence projects already ten years ago. The experience has been extended also to annotating and curating training data for AI projects.

Starting with customized software development, Chimaera's portfolio expanded steadily. Today, Chimaera is certified according to DIN EN ISO 13485 and a reliable partner for research, industry and medium-sized businesses. Our team of experts in image processing, AI and hardware optimization creates customized solutions for a wide range of use cases.

As a research-oriented high-tech company, we are in constant exchange with the important specialists in the current research landscape. This enables Chimaera to draw on the latest expertise from research practice and adapt it for its customers. We maintain close contacts with our alma mater, the FAU Erlangen-Nuremberg, but also with our contacts in the international research scene.

Career

Management

From researcher to researcher – at eye level, that's Chimaera. Both in our projects and within our company, we work to the highest quality standards. Through our own experience, we know the requirements of our customers very well and meet them as sparring partners and consultants at eye level.

We treat our employees in the same way. Everybody has his special field, but a strong team achieves more than the sum of the individual performances.
