l1r1 changes the way humans use software. l1r1 builds a system that understands human language and executes tasks automatically in the domain of business software.

We are l1r1 and we are building a cognitive AI for your business. Software today needs to be directed by humans, it does not plan and execute by itself. You as a user do not have to use software any longer via an interface but with pure verbal communication. Therefore, we are building a cognitive system by combining semantics, AI and language technology. We are not inventing something new, but we are using current software in such a way that it uses its full potential.

We need highly qualified employees that take the lead and responsibility to build something great. The top experts are needed.
