David Chung
Coaching Infrastructure Architect

I build the systems behind better coaching businesses.

I write about AI, operating systems, marketing infrastructure, and the parts of a business that quietly decide whether good work gets found.

Operating bias

Clarity comes through building, not planning. Simple systems beat complex funnels.

What I work on

01 Build

Agentic infrastructure

Tools, prompts, data, and workflows arranged into systems that survive real usage.

02 Operate

Coaching business systems

Visibility, offers, CRM, content, and AI support for coaches who need less chaos.

03 Publish

AI Didn't Fail. The Way We Rolled It Out Did.

A video about AI getting more expensive than the workers it replaced has been sitting in my head. The tech didn't fail. The rollout did, and that's a very human, very fixable problem.

The Best-Disguised Procrastination Has a Roadmap

I almost spent a month building the perfect brain for my AI agents. The deals that pay rent were sitting unclosed the whole time. The bigger the build, the better it hides.

The New Model Is a Blueprint for Surviving Without It

I got access to Fable 5 and the first question was obvious: what can I build? Then the clock showed up. And the question shifted. If I only have two weeks with this, how do I make it last? That question changed everything I did with the time.

Agent Work Is Theatre When Bash Would Do

An agent announcing it will 'set up your knowledge system' and then running the same commands a script would have run. That feels like progress. Often it is theatre.

Verify the Running System, Not Your Memory of It

I opened a session to fix an open loop that was already closed. The only thing that told me the truth was the live process, not my notes about it.

I Built the Factory to Avoid the Work

I spent a full day building a system to dispatch work to AI agents. The work I was avoiding took fifteen minutes by hand. The factory was the avoidance.

Clients Aren't Buying AI. They're Buying Relief

I'm good at finding the issue and reaching for the fix, and the fix usually has tech in it. What I'm working on is the two things I skip on the way there: sitting in the pain, and painting what the work feels like once it's gone.

The 61-Point Gap

Most people in your company can use AI. Almost none of them do. That gap is not a tools problem. It is a bridge problem.
