The One4All Curriculum

Where Academic Rigor Meets Practitioner Mastery.

The Markowitz-Van Dijk Protocol

A Legacy of Nobel-Prize Rigor, Evolved for the AI Era

An oldie: Our founder and principal Erik van Dijk together with Harry Markowitz. Doing a joint lecture for an audience of Dutch institutional investors.

Our methodology is anchored in the landmark research of Nobel Laureate Dr. Harry Markowitz and Erik L. van Dijk. Dr. Markowitz was a rare visionary—an eminent scientist who remained deeply embedded in the practitioner world throughout his career. 

The Markowitz-van Dijk Protocol is born from a rare intersection of worlds. While fundamental academic research often remains insulated from market realities, and practitioner strategies frequently lack theoretical depth, our Protocol rejects this divide.

We believe that elite practical execution requires the disciplined incorporation of the world’s most rigorous applied academic studies. 

Our partnership—featured in the Financial Analysts Journal—was built on this conviction: taking the mathematical precision of a Nobel-level framework and forging it into a heuristic for global strategic application. 

Today, we evolve this legacy by integrating AI as a primary tool for modern strategic mastery. 

If you want to know more about Dr. Markowitz, you can click here for more information on his Wikipedia page (which also contains a reference to our joint work). Or you can google "Markowitz Van Dijk heuristic" to get more details about our joint work.

The Three Pillars of the Protocol

The core methodology behind every One4All course, ensuring consistency, clarity, and mastery.

  • Rigor

    Our foundation is built on scientific logic. We don’t follow 'guru' trends; we use a verifiable, peer-reviewed audit system to ensure every course is theoretically sound and logically unshakeable.

  • AI

    We treat Artificial Intelligence as a second-nature tool, not a replacement for thought. The Protocol provides the human-led framework to harness AI for rapid, high-quality execution and 'practically lethal' competitive advantages.

  • Support

    We bridge the gap between learning and doing. Whether navigating business setups or complex investments, our curriculum provides the direct support and practical tools needed to master your specific professional challenges.

A Message from the Principal

Mastering the Intersections of Human Intelligence, Machine Speed and Entrepreneurship

In the changing world we live in, success belongs to the Practitioner-Scholar—the founder who can bridge the gap between scientifically-underpinned logic and 'practically lethal' entrepreneurial execution. At One4All, we don't just teach you how to use AI and other tools; we give you the Markowitz-van Dijk Protocol to ensure those tools actually build your bottom line. You bring the ambition. We’ll provide the roadmap to mastery. Let’s get to work together!
