Matthias Schoen is a Chief Operating Officer @Ziegert Group at Ziegert Group. He possess expertise in start ups, online marketing, business development, unternehmensstrategie, strategisches management and 17 more skills. Colleagues describe him as "It's not easy building something from scratch, and it’s not easy sometimes for a developer dealing with product and business people. So, when I started working with Matthias, I was honestly surprised to see how he was able to cope with all aspects of the development of Trademob’s Mobile Demand Side Platform. Notwithstanding the fact that Matthias needed to manage the relationships with big clients, secure support for Trademob’s mobile DSP within the company, or just deal with an ever growing team, it was always amazing to see how he could dive into machine learning, probability theory, supply side integration or infrastructure scaling problems. His leadership united development, data science, operations and sales from envisioning, through building and ultimately scaling the product. I am glad that I had a chance to work and learn from Matthias, I would work with him again in a heartbeat.", "Matthias and I worked closely together while building Trademob’s outstanding Mobile DSP. With his clear results-oriented mindset, he led all product development teams and built a coherent strategy for the DSP platform development. With his passion and enthusiasm, Matthias always focused on client needs and supported the teams to successfully sell the DSP product to new customers. He leveraged his deep product insights and helped to build a solid customer base. I highly recommend working together with Matthias.", and "I had the pleasure to work with Matthias during late 2015, when he helped us at Wooga with structuring the marketing team's budgeting process and coached some of us in business negotiations. Personally working with him more closely on the latter, I was able to learn a great deal from him - from preparing for the discussions to how to respond in different situations of the negotiation process. I was always impressed by him and his experience. He was also always disposed to have follow ups and debate how to best approach next steps, which made working with him a great experience."
