Chief Marketing Officer - Enterprise Solution @ HRS Group

About

With more than 15 years of marketing leadership experience, today I serve as the Chief Marketing Officer at the HRS Enterprise Solution, a prominent provider of AI-infused technologies to the global business travel ecosystem. My whole career has been built on one simple principle: there is only one boss — the customer. I specialize in Customer Management , Marketing Technology (MarTech), and digital growth strategies. Over the years, I have led global teams and scaled Customer organizations at companies such as HelloFresh, Gorillas, Zalando, SparkNetworks and IONOS. My expertise spans CRM strategy & lifecycle management, retention & loyalty, marketing automation, and subscription business growth. As Co-Founder of Sparkplant, the leading germany Braze-Agency, I have also gained deep experience in MarTech implementation, as well as data integration and automation initiatives that optimize technologies and drive measurable business impact. At HRS Group, I now focus on customer-centric growth, pragmatic AI adoption, and data-driven decision making. For me, marketing is not just a support function, but a strategic driver of transformation that creates tangible value for companies and their customers. Throughout my career, I have built marketing ecosystems that combine technology, strategy, and people. From CRM frameworks that increase customer lifetime value to retention models that reduce churn, the collaborative teams I’ve led have always centered on profitable growth. I also advise and invest in startups such as sproos! in New York, working with founders to navigate the challenges of scaling customer-focused organizations. What motivates me most is building teams that continuously learn and improve. I lead with clarity and pragmatism, and I enjoy translating complex topics into simple, actionable strategies that organizations can implement step by step. Core areas of focus: CRM, Loyalty & Retention | Marketing Technology | AI in Marketing | Digital Growth | E-Commerce & Travel Tech | Leadership & Transformation
