We are WE BUILD AI and a growing startup from Cologne. We build AI- and Data Solutions for the German Mittelstand and corporations. At our company, systems are being developed that go into production and earn or save money. PoCs for the drawer make others.

You will be responsible for our marketing. That means: together with our Founder, you will build Inbound and Outbound parallel, identify our target customers, plan campaigns, and set them up. From the first LinkedIn post to a completed ABM sequence.

What sets us apart? We combine technological excellence with genuine enthusiasm and openness. In doing so, we create an environment where responsibility is taken, teamwork is lived, and new ideas are welcome.
