We are building the infrastructure for the next generation of AI-driven recruiting.

While others are still just talking about AI, we have long since put it to work:

Our AI agents conduct calls with thousands of candidates every day—qualifying them, scheduling appointments, and managing entire recruitment processes—fully automatically and in real time. At Plug&Hire, we are building the infrastructure for the next generation of recruiting.

We are a team of experienced, successful founders, and we are hiring for our latest, funded startup in Stuttgart.
