You've built something real.
The finances haven't kept up.

Most SaaS founders up to $10M ARR are making big decisions without the financial capability to back them up. Wherever you are on your journey, the starting point is the same: know where you actually stand.

The Startup’s Dilemma: Strong Growth but No Grip on Finances

In the world of startups, a common challenge emerges: rapid growth paired with a lagging finance function. I’ve seen this firsthand as a CFO.

Does any of this sound familiar?

You know the revenue number. You can't explain what's behind it.
Your accountant keeps the books clean. Nobody's telling you what the numbers mean.
You're making hiring, pricing, and growth decisions without the financial foundation to support them.
An investor or board member asked you a question last week and you couldn't answer it confidently.
You're growing. You just can't tell if you can afford to keep growing.

About

I help SaaS founders understand their own business.

Two decades in CFO roles across ANZ and Asia including Amazon and Groupon. Before that, investment banking and a CA qualification that taught me how numbers work under real pressure. I work exclusively with B2B SaaS and AI founders up to $10m ARR.

SaaS founders work with me because:

I start with a diagnostic, not a proposal.
I build your capability, not your dependency on me.
I work with founders at the stage where the financial decisions are hardest and getting them right actually changes the trajectory of the business.
