About Us
Our decision models fully and machine-readably map the logic of laws, ordinances, and complex regulatory frameworks. Routine checks are thus automated and transparent, with the decision remaining with the human. We build this technology for public administration as well as for regulated companies. Authorities currently use it in areas such as building permit and wind power procedures. At Rulemapping, we are revolutionizing the world of rules and laws, developing the open standard for digital law with our Law as Code approach.
Supported by the Federal Agency for Disruptive Innovation (SPRIND) and anchored in the federal government's modernization agenda, our unique combination of Rulemap and language model delivers reasoned, legally sound, and verifiable results. We bring this groundbreaking technology wherever processes run in large numbers or high complexity, in Germany and internationally.
Together with you, we want to drive this vision forward!
