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.
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.
Follow the operating layer
Board-ready AI strategy, operator-grade technical depth, and weekly signal from the AI market.

Everything financed this week has a longer duration than the contract underneath it — and that mismatch now runs through all three lenses at once
Model layer
For architects tracking model capability shifts.

Six releases in five days, and the model you can benchmark stopped being the model you can run
Operating layer
For builders operationalizing agentic work.

Human approval finally got measured, and it caught 13.6% of dangerous commands — the control most enterprises built their agent policy on is the one that just failed its first published test
Procurement surface
For buyers watching AI reshape software.
Latest / Issue 16
Two opposite answers shipped in three days to the same question: does an agent come in through the front door as a user, or get assigned work inside the system of record?
Research
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
Global scale
Five concurrent enterprise programs, a $30M portfolio, 120+ contributors, and CEO-active platforms across a global public company.
Technical depth
Data, data science, machine learning, software engineering, agents, RAG, model routing, evals, and the operating layer between them.
Public body of work
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.
