    Simon Sonnenberg

    33 years, Managing Partner.
    Idea Creator & Business Designer

    For 7 years, I have been self-employed in the fields of innovation, business development, digital business models, and strategic communication. In addition to founding media projects, I have been guiding various clients through digital transformation for years. As a campaign and sales manager, I previously worked in a Munich-based media agency, responsible for partnerships and the marketing of an online & social media portfolio (with acquired new clients such as Ergo, Nike, Red Bull, Rodale Motor Press, or Hermes). Journalistic publications, speaker in adult and student education, moderation of numerous web talks, and speaker at conferences complement my perspective on (digital) communication of various topics.

    Software Architect & UI/UX Expert

    For over 18 years, I have successfully accompanied diverse and challenging projects for renowned companies such as Gruner and Jahr, Otto, About You, Porsche, as well as non-profit organizations. My wide range of tasks extends from initial conception through design, implementation, and testing to the delivery and ongoing operation of tailor-made software solutions for web, mobile, and desktop. Customers benefit from my extensive experience, both from a user perspective and in terms of technical feasibility. This results in innovative and user-oriented solutions that not only meet my customers' expectations but also provide sustainable added value.

    Communication Designer

    For over 10 years, I have been working as a reliable partner independently for local startups as well as international major clients and network agencies. Among my recurring clients are major car manufacturers located in NRW, insurance companies, and "love brands" like tonies. Branches of various advertising agencies or film production houses in the vicinity regularly make use of my services.
