About

I read businesses for a living. The read comes first.

Before anything gets built, I want to understand how your business actually runs — where it senses, where it decides, and where the whole thing quietly routes back through you. What I build afterward answers what the read finds. This page is the point of view you'd be hiring.

Six operating systems, shipped in public

An operating system here means the full workspace a business runs on day to day. Six of them are listed on Notion’s official Marketplace, where anyone can open one and judge the build quality directly.

A method you can inspect before buying

The Business Nervous System read rates the same five functions on every business it touches. Because the instrument is written down, you can watch it work before hiring it — five demonstration reads are published in full.

Held to its own standard

This practice runs on the workspace it deploys for clients, and it sits for its own read. The self-read is published with the same five ratings — including the ones that came back degraded.

Why the read comes before the build

Most help arrives with the answer already decided.

A bookkeeper sells books. A systems person sells a system. An automation shop sells automation. Each one shows up holding the tool it already planned to sell, then goes looking for a reason to install it. The business underneath rarely gets read closely enough to know whether that tool answers the real problem.

I work the other way around. The first thing I produce is a diagnosis. Once the constraint is named, what to build becomes obvious — and sometimes the right build is smaller and cheaper than what you came in expecting to buy.

A business is a system that senses, decides, and regulates. Read it that way and the bottleneck stops hiding.

What I actually do

I treat a business the way a clinician treats a body.

The method has a name — the Business Nervous System. I look at five functions, rate each one against real evidence, and write the single constraint holding the business back in one plain sentence.

The five functions

  1. Sensing. Whether the business can see what's happening — in the numbers, in the work, in time to act on it.
  2. Signaling. Whether what one person knows reaches the people who need it, without a hallway conversation.
  3. Processing. Whether work moves to done on a path someone other than you could follow.
  4. Deciding. Whether calls get made without everything queuing behind the owner.
  5. Regulating. Whether the business catches a small problem before it turns into an expensive one.
And then the build

The structure follows from the finding.

A workspace that holds the knowledge, so it stops living in one memory. Automation where it earns its keep, wired onto processes that are actually written down. All of it documented, so the structure keeps working once I'm gone.

Where this came from

I learned it by watching businesses break in the same place.

I left an elite entrepreneurial MBA partway through, having concluded that the interesting problem lived outside the case studies. It was in the gap between how owners describe their business and how it actually runs. I went looking for that gap in real operations — trades, property, mission-led work, professional practice — and kept finding the same thing.

Owner-led businesses rarely break at the work. The craft is usually the strong part, and it's why people pay. They break at everything around the work: books too far behind to decide from, knowledge that lives in one memory, decisions with no clear owner. That pattern is what this practice exists to read and repair.

The conviction underneath it

The structure should outlive the consultant.

I'm suspicious of work that makes a business depend on the person who did it. If you still need me in the room a year later for the thing to function, I built it wrong. Everything I make is meant to be operable without me — readable, documented, and yours. That's the test I hold my own work to.
