Bespoke operating systems

for the office behind the office

Upgrade your office

Your office runs on inherited habits, an overworked EA, and a folder structure that made sense three assistants ago.We can fix that.

Who we are

Built from the inside.
Tested under pressure.

More about us

We've spent years running the day-to-day for senior executives, founders, and high-stakes principals. The problem was the same in every one: a brilliant team keeping everything together on memory and habit, with no real system underneath. So we built one.

None of it is theoretical.

Every part of this was built from inside a real working office. The tools, the documented systems, the whole way it operates. Refined under real pressure, on a real team, for a real principal. Every system has been tested in offices where the pressure is constant and the margin for error is zero.

Most principal offices were never designed. They accumulated. Yegz Advisory diagnoses how the office actually works, redesigns the parts that need it, and builds the custom software that makes the redesign hold.

How it works

Two phases, one outcome.

Phase One

The Blueprint

Two weeks · written plan

A two-week diagnostic of how your office runs today. At the end, a written plan: what's working, what isn't, which tools we'd build, how to run the processes that don't need software, and a fixed-price proposal for the Build.

Phase Two

The Build

90 days · custom build

90 days of bespoke development and onboarding. Custom-built web apps, documented SOPs, and a plan for how to use the system from day one. Scope and price set by the Blueprint. Engagements range from a single tool to the full suite.

Handoff

The Inheritance

Included with every build

The office walks away with everything it needs to keep running the system without our team in the room: SOPs for the tools and for the office processes around them, credentials, decision history, AI troubleshooting, and an onboarding guide for whoever fills the seat next.

Included WITH THE BUILD
The Suite

Five connected tools.
One connected office.

Every Build delivers up to five custom tools, each one solving a real, specific part of what an office does in a day. The tools stand on their own, so you can take the ones that fit and skip the ones that don't.

But they're built to talk to each other, so when more than one is installed, the suite stops being five separate tools and starts being the connected infrastructure the office runs on.

Get started

A 30-minute call to see if it's a fit.

The on-ramp is a free 30-minute call. We talk through what your office looks like today, what's working, what isn't, and whether the Blueprint makes sense to commission.

No slides, no homework, no commitment. If we both think there's a fit, the Blueprint can start within two weeks.
