The Most Valuable AI Output Was a Refusal to Compute
How a symmetric billing bug made a losing campaign look profitable — and why a production AI system should sometimes refuse to produce an answer.

I'm David Leathers, an Applied AI and technical product leader who turns difficult revenue and operational problems into production software, governed agentic workflows, and marketplace infrastructure. My background spans AI-native product development, performance marketing, telephony, real-time marketplaces, and executive operations.

Selected work
Production marketplace
A multi-tenant performance marketplace connecting buyers and publishers through real-time bidding, telephony, routing, attribution, billing, payouts, partner workflows, and production AI.

Partner-facing and operator-facing agents can inspect and change real system state, but mutating actions are scoped, confirmed, version-checked, audited, and outcome-verified.
Role Product & safety design

How I work
I don't position myself as the engineer who manually authors every line of production code. My role is to define what the system must do, understand the underlying technical concepts well enough to challenge implementation choices, direct AI-native delivery, validate the result, and own what happens in production.
How I build with AI →Applied AI
Three production systems where an agent's output changes something real — and where the interesting engineering is in what happens between the model's suggestion and the system's state.
Natural-language partner support and production configuration actions, behind scoped permissions and explicit confirmation.
Governed internal agent access to administrative workflows across the platform, every tool typed and audited.
Finance, reconciliation, analysis, investigations, and operational support — with money movement reserved to a human.
Leadership & scale
Before building AI-native software systems, I operated at executive scale in performance marketing. That experience is why I care about economics, attribution, routing, conversion, operational reliability, and whether a system produces a business result — not whether the technology sounds impressive.

How a symmetric billing bug made a losing campaign look profitable — and why a production AI system should sometimes refuse to produce an answer.
The parts of AI-native delivery that are not the code: requirements, acceptance criteria, adversarial review, and owning the production outcome.
Model output is not authorization. What it actually takes for an agent to change real system state safely.
I'm interested in senior Applied AI, technical product, AI transformation, revenue-systems, and related leadership opportunities — especially roles where software has to survive contact with real operations.
