JUST ADD AI (JAAI) helps companies understand the latest AI technology and apply it to their business. The focus of JAAI is on programming scalable AI solutions that immediately create value for our customers. Once an AI solution is market-ready and has recorded first customers and revenues, it is spun off into a subsidiary and scaled there. To secure the growth of the spin-offs, participations are issued in the subsidiaries and strategic partners are brought on board.

Working in the JAAI Group is characterized by open communication. Problems are solved together by teams of top specialists from the fields of AI agents, language processing (LLMs), computer vision, big data, and robotics, as well as experienced IT managers and architects. Our mission: "Unlock Human Talent". AI opens up new scopes for the development of the full potential of human talents through the automation of repetitive and time-consuming tasks.
