Christian Müller

Interim Client Service & Business Development @ Self Employed

About

Client leadership and commercial growth - that's where I operate. My background spans agency, brand and tech. I'm equally at home managing a strategic account and building new business pipelines from scratch. I've worked with brands like Airbnb, BMW, Spotify, EY, Jaguar Land Rover and Zalando, in roles ranging from Account and Client Service Director to Business Development Lead - both permanent and freelance. What connects all of it: acting as a trusted senior who's able to build and lead teams, translate between client goals and commercial growth and stay sharp when environments are complex and stakeholders are many. Based in Berlin, open to conversations around client leadership, enterprise sales and business development. Nice to meet you!
