OAK & NINE
About

Seasoned consultants who wanted the picture to stay current.

Oak & Nine is a small, senior team who spent their careers inside other people’s businesses, and built the thing they always wished they’d had.

Understanding how a business really runs has always taken time, and the result was usually a document. However good it was, it stayed a snapshot, and it went out of date within a quarter.

That clarity was hardest to reach for the businesses that needed it most, the ones without a strategy function to lean on. They made good decisions with less of the picture than they deserved.

We built Oak & Nine so that picture assembles itself from what a business already has, stays current, and belongs to the business. We measure ourselves on one thing: whether something in your business actually moved.

How we work

Our Values

01
Judged on results

We start with one function and prove the value there. We measure ourselves on what changed in your business.

02
Your business, your terms

Your data, your agents and your knowledge base belong to you.

03
The same faces after go-live

Your contacts remain the people who built your base and know your operation.

04
Transparency

We call out where the evidence is thin and when the answer may not be the one you wanted.

05
Verified, not inferred

Nothing counts until a person has confirmed it. We hold ourselves to the same standard we built into the product.
