legacy-use.com | Co-Founder | Munich, Germany | Remote possible | Full-Time |

Most legacy software has no API and cannot be automated with Agentic AI. At our company builder (schub.tech) we had the same problem in one of our ventures and build ourselves a solution: based on computer-use, we can insert & extract information out of any software.

We believe this toolstack is useful to many others, hence we spin it out as a company. We are looking for co-founders to join us on the journey to open up backbone of German Mittelstand to AI automation.
