    Working at adjoe

    Make the difference!

    For me, working at adjoe is about having great ideas and getting different opinions on board. Yet, we still manage to be pragmatic, flexible and fast. I have never experienced this before – in other jobs, things have ended up being either too chaotic to manage or discussed to death before the project even started.
    Max, Product Lead
