Global scale
I run AI where trust, adoption, and economics all matter.
Five concurrent enterprise programs, a $30M portfolio, 120+ contributors, and CEO-active platforms across a global public company.
D. Brian Letort, Ph.D.
AI strategy for people who have to operate it.
I write about the systems layer of enterprise AI: the models, data foundations, agentic workflows, economics, governance, and operating patterns that turn experiments into durable capability.

What to read next.
Industry intelligence
AI market signal, organized weekly.
Cross-stack flywheel
AI Stack Weekly
For officers tracking AI market movement.
Latest / Issue 10
The week shifted from model announcements to the physical bottlenecks that decide who can serve agentic demand.
Model layer
The Model Pulse
For architects tracking model capability shifts.
Latest / Issue 10
No new model reset the board; the model-layer story moved to availability, cost, and serving economics.
Operating layer
Agent Techniques Weekly
For builders operationalizing agentic work.
Latest / Issue 10
Background agents crossed from novelty to operations: the hard part is the control loop.
Procurement surface
The Application Layer
For buyers watching AI reshape software.
Latest / Issue 06
The application layer moved from copilots to governed builders and priced work.
Research
Context Compilation Theory.
A foundational paper and three-paper trilogy on the systems layer between retrieval and reasoning — the governed, measurable, optimizable layer where reliability lives, where provenance is enforced, and where token economics becomes a design surface rather than an accounting line.
Why trust the signal
Strategic altitude. Technical depth. Global scale.
Technical depth
I can move from boardroom framing to code-level architecture.
Data, data science, machine learning, software engineering, agents, RAG, model routing, evals, and the operating layer between them.
Public body of work
I write, teach, publish, and build in the open.
A Context Compilation research program, PhD teaching, 16 Pluralsight courses, two books, and a weekly AI industry corpus.

Speaking and executive briefings
I accept a small number of speaking, board, press, and executive briefing requests each year.
