Riaru is the most globally successful company: an online multiplayer game that allows its users to dive into foreign worlds, realize themselves and even profitably market their own business. Making the world a better place for everyone is Riaru's declared goal.
Mic desperately wants to contribute to this idealistic idea. But even an excellent degree in software development is meaningless when acquired in a small Argentine town. The career leap to Europe seems hopeless. But then Tuuli, the founder of Riaru, notices Mic. The job at the Berlin headquarters is like a dream. Until Mic wakes up.
Paul K. Lunow, himself a founder and programmer, provides deep insights into the structure of tech corporations and the handling of metadata in this exciting cyber novel.

Hi, I'm Paul. And you've landed on my personal website.

As a child, I dreamed of becoming a writer. This desire inspired me to program a literature portal – a place where my friends and I could share our ideas and thoughts during school time. This dream became a journey: 20 years in the tech industry, in which I worked in almost every conceivable role around technology. Now my childhood dream has come true: In January 2025, my first novel, Riaru, was published.
Today I live at the intersection of technology, leadership and creativity. As CTO at Vention, I help companies implement successful technology projects. In my podcast, I share my knowledge about tech products and leadership. I also accompany teams and companies as a mentor and consultant to find orientation in the digital world.
This website reflects all facets of my work and passion. Whether you want to pre-order my book, are looking for inspiring podcast episodes, or are looking for a sparring partner for your digital challenges – I look forward to your message and your feedback.
Product&Cake Podcast is the perfect companion in the wild Product-Tech world.
Ghonche and I met at mobile.de in the podcast studio. No one needed the studio at the time and we had cake with us, so we recorded a podcast for fun. The feedback in the internal chat was overwhelming. Just like the fun we had during the recording. So we kept going!

In this episode of Product and Cake, Ghonche Tavoosi and Paul Lunow delve into the fundamentals of identifying your target market and why it’s critical to focus on the customer’s needs rather than demographic details.

They explore their favorite tools for task management, collaboration, and product design, offering insights on how each can enhance your workflow.

Whether you’re just starting with an idea, transitioning to an MVP, or managing a mature product, this episode will guide you through each stage.

Whether you’re building a startup or managing a growing business, this episode explores when the product management role becomes essential and why it can make or break your company’s success.
Bring me into your team! I help find ways in the vast sea of possibilities.
As a founder of several companies, team leader and strategy consultant, I have gained comprehensive experience in recent years: from building and leading motivated teams to successfully pitching ideas to implementing scalable solutions. Today I pass on this knowledge – to people, teams and companies that are looking for orientation, want to overcome challenges or achieve their goals faster.
Well-founded insights into founding, growth and leadership – combined with practical solutions.
I help you make quick decisions and recognize wrong paths early.
Fresh impulses that help you see complex challenges from a new perspective.
It always excites me to support people and companies in getting the best out of themselves – motivated, efficient and with a clear focus on the future. If you feel addressed, let's find out together how I can support you or your team. Following my motto: "The answer to how is yes!"
Follow me on LinkedIn or write me an email and we'll meet for a real or virtual coffee.
