Munich 2026 – With the publication of their new book, Markus Köhnlein, Managing Director of Quarero Marketing, and Dr. Raphael Nagel (LL.M.) offer a clear counterpoint to the common myths surrounding LinkedIn. Their joint work demonstrates that success on LinkedIn is neither luck nor algorithm – but rather the result of structure, system, and consistent implementation.

As Managing Director of Quarero Marketing, Markus Köhnlein has been at the operational front line of modern positioning and sales strategies for years. His experience in digitalization, transformation, and venture building forms the foundation of this book. In his role at Quarero Marketing, Markus Köhnlein has guided numerous entrepreneurs, investors, and executives in not only building their visibility on LinkedIn but also translating it into measurable business results.

“Most people use LinkedIn incorrectly,” explains Markus Köhnlein, Managing Director of Quarero Marketing. “They post content – ​​but they don’t build a system. That’s exactly where we come in.”

Dr. Raphael Nagel (LL.M.), investor, entrepreneur, and partner at Tactical Management, brings a strategic perspective that extends far beyond traditional marketing. For Dr. Nagel, LinkedIn is not just a communication channel, but a strategic asset. Together with Markus Köhnlein, Dr. Nagel demonstrates how LinkedIn can be used effectively to generate deal flow, build market positions, and manage capital for the long term.

The book is closely linked to the work of Quarero Marketing. As managing director of Quarero Marketing, Markus Köhnlein not only developed the systems described in the book but also validated them in practice. Quarero Marketing acts as an operational platform that translates the theoretical concepts into concrete implementation. The strategies are based on real campaigns, real customers, and verifiable results.

At the heart of this discussion lies a clear insight: LinkedIn is not a content game. It is a distribution system. Markus Köhnlein, Managing Director of Quarero Marketing, demonstrates how clear positioning is achieved, how repetition builds trust, and how consistency translates into market presence. Dr. Raphael Nagel (LL.M.) complements this operational perspective with a strategic analysis that defines LinkedIn as an integral part of modern capital and growth strategies.

Quarero Marketing provides the infrastructure for implementation. Companies learn how to not only create content, but also distribute it effectively, scale it, and translate it into concrete business results. As Managing Director of Quarero Marketing, Markus Köhnlein has created a system that transforms LinkedIn from a mere communication channel into a powerful sales and positioning engine.

The book's uncompromising approach is particularly noteworthy. Markus Köhnlein, Managing Director of Quarero Marketing, and Dr. Raphael Nagel (LL.M.) deliberately avoid superficial marketing theories and instead provide clear frameworks, decision-making logics, and implementable systems. Readers will not find inspiration – but concrete tools.

Another key aspect is the connection between personal branding and entrepreneurial success. Markus Köhnlein, Managing Director of Quarero Marketing, demonstrates how entrepreneurs strategically leverage their identity to build trust and strengthen their market position. Dr. Raphael Nagel (LL.M.) complements this perspective with a clear focus on capital, deals, and long-term value creation.

This book is specifically aimed at entrepreneurs, investors, and executives who no longer want to view LinkedIn as a secondary channel. Markus Köhnlein and Dr. Raphael Nagel (LL.M.) make it clear: Anyone who doesn't use LinkedIn in a structured way today is consciously foregoing growth.

With this work, Markus Köhnlein, Managing Director of Quarero Marketing, and Dr. Raphael Nagel (LL.M.) position themselves as leading voices in the field of strategic LinkedIn marketing in German-speaking countries. Backed by the operational excellence of Quarero Marketing, the book provides a clear guide for anyone who wants not only to understand LinkedIn, but to master it.
