You’re great at solving data problems. So why does it still feel like you’re stuck?

You lead a data team or aspire to do so. You’re smart, experienced, and care deeply about doing great work.

But despite all your effort, something feels off:

☔️ You’re drowning in ad-hoc requests instead of shaping strategy

💪 You want to make a bigger impact but somehow it doesn't happen

🤔 Stakeholders don’t fully trust your team

🗺️ You’re unsure if your current strategy is even right for your company

🎖️ And deep down, you’re wondering: “What will actually get me to the next level?”

If any of this sounds familiar, you’re not alone.

I’ve worked with 40+ companies across the globe and I’ve painfully experienced all of these challenges.

    The masterclass is gold! 🏅

    Forget about buzz words and lofty principles that leave you wondering how to implement them - Sebastian takes a hands-on approach and shows you HOW to become a great data leader!

    The bite-sized video course starts by a clear picture of what a successful data team looks like, the mindset that gets you there, and the values and principles that sustain it. 

    From there, you’re guided step by step through practical methods and frameworks, all supported by ready-to-use templates that help you hit the ground running 🚀

    No company I worked for taught me how to actually manage a data team to create real business impact - until this masterclass.

    I had plenty of exposure to tools, platforms, and dashboards. But what was always missing was a clear, strategic framework for leading a team, aligning with stakeholders, and turning business needs into outcomes.

    This masterclass gave me exactly that: a complete operating system for building a high-impact data team.

    If you're a data leader—or want to become one—and you're looking to earn trust, deliver value, and get your team firing on all cylinders, this is the missing piece.

    The Data Action Mentor Masterclass delivers exceptional value through practical frameworks and ready-to-use templates that create immediate business impact.

    Sebastian's guidance on stakeholder communication and data strategy provided actionable tools I could use in my daily work right away.

    The material is top-notch and highly applicable.

    Sebastian brings a wealth of knowledge and experience, and his guidance has truly helped us elevate our data operations.

    My main goal was to improve the value our data team delivers to management, and this program has provided exactly what we needed. 

    Having access to pre-built templates rather than starting from scratch made a huge difference. In fact, I’ve already applied four of Sebastian’s templates and received positive feedback from our stakeholders, which speaks to their immediate impact.

I'm sharing all my "secrets" and I'm holding nothing back.

    ✅ The Objective - Service - Product Framework

    Most data initiatives fail because they are not tied to tangible business outcomes and objectives. This framework helps you close the gap between tech and business and will get your CEO on board with your mission!

    ✅ The Super User Self-Service Framework

    “Self-service is a myth!” - you’ve probably heard that before. I beg to differ. In this masterclass, I share my complete organizational strategy for turning this myth into reality.

    You’ll learn how to:

    • Identify and empower Super Users
    • Enable business teams to answer 80% of their own questions
    • Free up the data team’s time for strategic work

Who am I?

I'm Sebastian and I will guide you through this class. 👋

I have built impactful data teams for 40+ high-growth companies, including:

  • Rocket Internet (previously the world's largest venture builder)
  • Jumia (the first African tech company listed on the New York Stock Exchange)
  • Lazada.com (exited to Alibaba for $2bn+)
  • Zalando (one of Europe's most successful E-Commerce businesses)
  • Lieferando (exited to Takeaway.com)
  • Wasoko (largest tech merger on the African continent with MaxAB)
  • and many more

We are living in exciting times!

AI is changing the world and the impact on data teams is real.

Many CEOs believe they can replace their whole data team by AI agents. 🤯

In the age of AI, building strong data foundations and data teams with a relentless focus on business impact is more important than ever.

✅ Those teams who focus on understanding stakeholders and solving their problems will thrive

❌ While teams who only chase shiny tools will perish. 

This masterclass is not an AI course. There are already millions of those. 

Instead, this masterclass provides you the actionable frameworks, strategies and templates you need to build a foundation that helps you thrive in this new era.

Wall of Love ❤️

  • The class was packed with insights and easy-to-follow rules and workflows that I could use to build my own set of mental models, tools, templates and rules to apply to daily business operations. 

    I love the fact that it delivered on the more interpersonal topics - how to talk to stakeholders to receive the needed input and how to lead a team.

    Piotr, Senior Marketing Analyst
  • My main goal was to improve the value our data team delivers to management, and this program has provided exactly what we needed. A couple of my favorite lessons include the KPI Dimension Framework, which clarified key definitions and provided solid input for our team's roadmap. I also found the section on organizational strategy particularly insightful, in terms of spending your team's time wisely.

    Jeroen, Team Lead Data & Analytics
  • I really wish I had this a few years ago. It’s a concise and well-structured summary of all the mistakes one can make and some of them I still regularly fall into today.

    I’ve spent far more money on materials that offered far less value than this. Thanks for putting this out there. Much appreciated.
