For established owner-led businesses

Your business has a team.
So why does it still need your brain to run?

BGB helps established business owners get how they think, decide and solve problems out of their head and into the business. So it can work with or without them.

Things owners quietly tell themselves

It feels like eight different problems.

But listen closely. They are all saying the same thing.

You do not have eight separate problems Your business still needs to borrow your brain to run.

That is why the staff questions, client fires, missed standards, slow decisions, broken holidays and Sunday-night laptop all travel together. They are symptoms of the same thing.

The business has your labour. It has your people. What it still does not have is enough of your judgement.

BGB puts that judgement where the work happens, so fewer things need to climb all the way back up to you.

The Black Diamond System

Get your judgement out of your head and into the business.

Your business does not need to be easy. It needs to be simple enough for good people to know what matters, make the call and see when something is off.

We turn the way you think into clear priorities, numbers, standards, roles and ways of working. Your team handles more of the repeatable problems. You get your brain back for the problems worth solving.

Free 2-Minute Assessment

Not sure where your business actually sits?

Two questions. Twenty possible positions. Your result tells you exactly where you are on money and freedom — and what's holding you back from moving up.

No email required to start. Takes 2 minutes.

Stephen did it in his own business first.

LTrent does not need to borrow his brain
all day, every day.

It runs through one 45-minute meeting a week because the standards, numbers and decisions live in the business, not just in Stephen's head.

This is not theory dressed up as coaching.

It is the operating discipline Stephen used to unwind himself from the company he built.

Stephen O'Sullivan Sydney Business Coach - Australia's Largest Driving School Owner - BGB Founder

Today Australia's largest driving school runs through a single 45-minute meeting with Stephen each week.

LTrent has 120+ staff and 88+ franchises. The team carries the daily operation. Stephen gives his attention to the few decisions that genuinely need him.

That means he can:
Take 5x family holidays per year minimum
Take his boat out fishing whenever he wants
Ski the best runs and resorts around the world, all year

What changed for the owners who stopped carrying it all

Their businesses were already real. The change was teaching the business to make more decisions, solve more problems and keep moving without them.

What happens next

Find the work that still needs you. Then teach the business to carry it.

1

FIND WHERE IT COMES BACK TO YOU

We start with a short call to understand the decisions, problems and parts of the business that still cannot move without you.

2

FIX THE RIGHT THING FIRST

We identify the few changes that will remove the most pressure, then turn them into a clear plan your team can actually follow.

3

MAKE THE CHANGE HOLD

Your team takes on more decisions and follow-through. We help you resist rescuing the work and make the new way of operating stick.

The same work. Different levels of access.

BGB is built for established businesses that already work. You do not need us to invent the model. You need the business you have built to stop needing you in every decision.

Meet Stephen

A business owner who coaches business owners.

Stephen O'Sullivan built LTrent into Australia's largest driving school, then did the harder job: making sure it no longer needed him in the middle of everything.

He knows the difference between advice that sounds tidy on a whiteboard and a change that survives contact with staff, customers, cash flow and a busy Tuesday.

Stephen is based in Sydney and works with established owner-led businesses across Australia. See our Sydney business coaching page

Your business will always have problems. But they should be better problems.

Not the same questions, mistakes and fires your team should be able to handle without you. BGB helps your business think, decide and move without waiting for you, so you get your time and headspace back for the work only you can do: building the team, shaping the culture and deciding where the business goes next.

Common questions

Common questions about BGB

What does Building Great Businesses do?

Building Great Businesses helps owners unwind themselves from the daily running of an established business. We build the team, systems, numbers and accountability for the business to work with or without the owner.

Who is BGB best suited for?

BGB is best suited for owners doing roughly $500,000 to $5,000,000 in revenue with a proven business and a team, but who are still the person every decision, problem and client issue comes back to.

Is BGB only for Sydney business owners?

No. BGB is based in Sydney and works with business owners across Australia through an online coaching format.

Your business can keep borrowing your brain. Or you can start putting that brain into the business.
