Founded in 2017 by Jan Becker and Dejan Pangercic, the company is headquartered in Palo Alto, California, with additional offices in Munich, Stuttgart, Gothenburg, Tokyo, and Pangyo.

To date, Apex.AI has raised over $75 million USD from world-class venture, financial and strategic investors including AGCO , Airbus Ventures , Canaan , Continental AG , Daimler Truck , HELLA Ventures , Jaguar Land Rover ’s InMotion Ventures , LG Electronics , Lightspeed , Orillion , Toyota Ventures , Volvo Group Venture Capital and ZF . The company’s flagship product, Apex.OS, consists of two core components: Apex.Grace and Apex.Ida. Apex.Grace is an application runtime framework in the form of a software development kit (SDK).

It provides a robust framework for developing real-time, reliable, and safe applications. Core APIs are based on ROS 2 APIs with numerous extensions enabling real-time execution, reliable performance, deployment into large fleets, system state management, safety, security, and much more. It is safety-certified to ISO 26262 ASIL D.

Apex.Ida is a communication middleware delivering optimal high-performance data transport across use cases. These use cases range from fully autonomous vehicles with dozens of high-resolution cameras to small signals with ultra-high frequencies in safety-critical domains. Its core is based on a shared memory data transport with connectors into DDS, SOME/IP, MQTT, CAN, and many more protocols, all abstracted into a single application facing API.

Additionally, Apex.AI offers: Apex.Alan provides customers with a highly optimized and efficient software integration, development environment, build, test, and delivery process. Apex.OS for V&V enables record and playback of very large and diverse data streams, both time- and data-deterministically, which is crucial for replay, analysis, and performance evaluation of complex autonomous systems.​ Apex.AI’s software solutions are utilized across a diverse range of industries, including automotive, agriculture, medical, and defense sectors. The products enable developers to efficiently create and deploy safe, reliable, and high-performance applications, thereby accelerating the adoption of software-defined mobility systems.

Through its innovative software solutions and strategic partnerships, Apex.AI is at the forefront of transforming the mobility industry, facilitating the development of next-generation vehicles and systems. Find more English Speaking Jobs in Germany on Arbeitnow
