What I care about
Turning messy systems into clear decisions.
My work tends to revolve around measurement, decomposition, market structure, and building tools that make complicated problems easier to reason about.

Bryan Smith builds at the intersection of data science, investing, and product.
I write about experimentation, analytics, markets, and the practical side of building useful things. This site is the public home for my work: essays, dashboards, and the investing tools I am building in the open.

Here
You will find long-form writing, public dashboards, and a growing members area for deeper market research.
Focus Areas
Three threads run through most of what I publish.
Data science that survives contact with reality
Experimentation, decomposition, causal thinking, and measurement frameworks that are actually useful outside a slide deck.
Markets as a research problem
I am interested in building a process around tickers, relative moves, fundamentals, and investor workflow rather than hot takes.
Products that make insight usable
Dashboards and tools matter when they help people ask better questions and move faster from raw data to conviction.
