Our Story

I am Justin Lake, the Director and Founder of Think Numbers. I have spent more than twenty years in commercial finance and operations, working across six industries in roles that shaped how businesses plan, analyse and make decisions. Over that time I have led major system upgrades, built forecasting and reporting platforms and helped organisations redesign the way their data and processes work.

I started Think Numbers to solve a problem I saw everywhere. Businesses needed someone who could speak finance and build systems. They needed strategic thinking paired with technical execution. Most teams had one side but not the other. Think Numbers exists to bridge that gap so companies can operate with clarity instead of wrestling with broken processes and scattered data.

As a Chartered Accountant with an MBA from the Australian Graduate School of Management, I bring both strategic insight and hands-on delivery. I take a platform-agnostic approach and focus entirely on what will work best for your business and your team.

My aim is simple. Help build systems, data and processes that make your business faster, smarter and ready to grow.

Our Testimonials

Bernaley Olofernies (Head of Business Partnering)

We are lucky to have a project manager who can build Anaplan models at the same time. It made the discussions with external contractors a lot easier. You have also inspired me to do the model building training. Thank you very much for everything!

Neil Lambert Head of Investment Management and Reporting

Justin is a highly competent consultant with strong finance and Anaplan expertise. He quickly adapted to our complex organisation and worked very well autonomously and in a remote capacity. We were able to expand his role to manage multiple projects with multiple streams simultaneously across the Finance business unit, which he delivered on time and budget.

Andrew McPhail GM Finance

Thank you for all that you have done with what I call the finance transformation program across both Anaplan and Treaury projects. Without you at the centre of these projects and workstreams I doubt that we would have achieve as much as we have with these initiatives.
