A digital, self-paced masterclass for experienced data professionals who want to work on high-leverage projects (not just dashboards). 📈
Learn and apply the frameworks that I used to win stakeholder trust, earn a seat at the table, and lead with impact in 40+ companies across all continents.
Our students build data teams at the world's most respected companies:
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.
This masterclass gives you actionable frameworks, strategies, and mindset shifts to:
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.
Recommended!
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.

Over 17 years, I've built data teams and data infrastructure for 40+ leading companies across the globe. This course condenses all the frameworks that I have crafted and improved over time.
I'm sharing all my "secrets" and I'm holding nothing back.
5.5 hours of video material, split into 27 digestible and actionable sessions. You get lifetime access to the video material and all resources when you purchase the masterclass.
Dive deep into the control agility framework and avoid dangerous pitfalls on your quest to create massive business impact with your data team.

Use the Data Team Adjusted Lean Canvas to create a data strategy that sets you up for success.
This framework helps you map stakeholder needs directly to data architecture. Use it to:
Star Schema, Activity Schema, Data Vault, OBT?! I’m a fan of “mixed modeling arts”. Learn how and why I mix different data modeling approaches for maximum impact.
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!
“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:
Are you ready to level up your game and move from dashboard factory to strategic partner? 💥
I'm Sebastian and I will guide you through this class. 👋
I have built impactful data teams for 40+ high-growth companies, including:
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.
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.
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.
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.
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!
Your totally realistic, down to earth (ironic 🚀), lectures, and lo-fi methods of teaching are amazing - refreshing even.
Great course, amazing industry learnt insight, astounding delivery = amazing value.
The Data Action Mentor Masterclass delivers exceptional value through practical frameworks and ready-to-use templates that create immediate business impact.
I’m glad I signed up. Amazing content that is immediately actionable!
The course is excellent and the value for the price is outstanding given the quality of the content.
Sebastian has a unique ability to challenge your perspective and guide you through a thorough examination of your obstacles. The masterclass skillfully leads you from feeling lost in a jungle of challenges to discovering your own path to the promised land.
Your problem/solution and agility/control frameworks are true game changers, I can't recommend the master class enough.
I subscribed to your course and was blown away by the initial few hours and then got swamped with a project .... mea culpa and I fully intend to complete it
Hey man,
I'm sending you once more because the Data Action Mentor Masterclass is so spot on and useful!
Nice that you shared all these lessons, especially the resources
Last but not least...
I want your investment in this masterclass be 100% risk-free.
Whether you invested your own money or your manager paid for you, my refund policy is very simple.
If you completed the course, did all the homework, implemented the frameworks and you still feel that you didn't receive enough value, just write to me within 14 days and I will give you a full refund.
No questions asked.
Based on the incredible feedback I received from so many students I am 100% convinced about the value of this masterclass so that I can confidently offer this. I know that the frameworks in this masterclass work - both from my own experience and from my students.
The variable I don’t have control over is that you have to be the one to put the frameworks into action. 💪
