80% of CEOs are disappointed by their data teams

I’ve spent 17+ years building data teams and advising Founders, CEOs, and CTOs in 40+ companies across the globe.

During this time, many CEOs complained to me about one thing: Their data teams don't create enough business impact. ❌

They care too much about shiny tools, tech and dashboarding and not enough about measurable outcomes.

It breaks my heart to see so many data teams suffer because managers and stakeholders have given up on them. πŸ’”

The goal of this masterclass is to teach you all the frameworks, concepts and strategies to earn the trust and respect of your stakeholders and your CEO and to create massive business impact.

You may experience one or more of the following pain points:

    The Data Action Mentor Masterclass was a game-changer for me. 

    The biggest value came from the clear guidance it provided for navigating the wild and complex β€œdata jungle”. 

    I now feel much more confident in tackling day-to-day challenges as a data leader, especially in stakeholder communication.

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

  • Rocket Internet (previously the world's largest venture builder)

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.

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

❌ While teams who only chase shiny tools and tech 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.

    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.
