With the CELUM solution for Digital Asset Management we deliver the backbone and beating heart of modern content strategy. CELUM covers the complete lifecycle and allows unrivalled efficiency and cost reduction in linking content, processes and systems. We use state of the art technology and architecture. Our high performing solution is scalable and creates a great user experience. We can´t wait to show you Workrooms – the new collaboration tool that´s brings people, files and tasks together. Forget DropBox, Wunderlist or WeTransfer and fall in love with our products, as we did. We are all about content and collaboration and we re-invent how people work together and get content to work.

We do amazing stuff for the biggest companies and most loved brands in the world. Work with us for Porsche, WWF, Rosenbauer, Davidoff, Mammut, Scott Sports and many more.


Over the last years, CELUM has created its own full reactive technology stack, including Angular, RxJS, VertX and graph data models. Only the good stuff! Help us to find out what we can do with it if we push it to the edge. Do not be afraid if that is new to you: we believe in continuous learning and evolution so there are seasoned CELUMians and our architects team who will help you get up to speed. We run our own Kanban style process and other tailored agile paradigms and that are constantly evolving.
