About
Built for problems that don't fit neatly into one discipline.
548 Marjan is an independent decision science advisory working with organizations facing complex, consequential business problems.
We combine quantitative rigor with direct engagement — bringing together the evidence, methods, and context required to move from analysis to action.
Why 548 Marjan
The name goes back to where the idea began.
548 Marjan takes its name from the founder's childhood home.
His father worked in the energy industry, using time-series and spectral analysis of seismic data to infer geological structures deep below the surface.
The work left an enduring impression: complex systems can be understood by breaking difficult problems into tractable questions, extracting signal from imperfect evidence, and applying the right methods to each.
That idea became part of the foundation of 548 Marjan.
Founder
James Henson
MEng · MBA · Decision Scientist
James founded 548 Marjan after working across quantitative analytics, marketing science, and decision support in organizations ranging from Series B companies to the Fortune 25.
His work has spanned technology, telecommunications, and financial services, with a focus on measurement, experimentation, forecasting, risk, and resource allocation.
548 Marjan brings that experience into an independent advisory built around a simple idea: rigorous quantitative work should ultimately improve what an organization does.

Advisory is the beginning.
548 Marjan is being built as more than a consulting practice.
Our long-term work extends across applied research, software, and decision systems designed to help organizations learn, adapt, and act more effectively over time.
The advisory gives us a place to begin: working directly on difficult problems, developing the methods, and learning where better systems can create lasting value.
