Years of Experience
I’m Justin Lake, the Director and Founder of Think Numbers. With over 20 years of experience in commercial finance, I’ve had the privilege of working in senior finance roles across six different industries. My journey has taken me to the forefront of numerous finance system implementations, strengthening the commercial and finance capabilities of organisations across Australia.
I founded Think Numbers to solve a common business challenge: the gap between financial expertise and technological insight. I understand how difficult it is to find the right balance when undergoing major system changes. That’s why Think Numbers is built on the principle of providing that perfect equilibrium—helping businesses grow with confidence and clarity.
As a Chartered Accountant with an MBA from the Australian Graduate School of Management, I bring both strategic vision and hands-on experience. I’ve worked extensively with a wide range of finance systems, including SAP, Oracle, TM1, and Microsoft products. My platform-agnostic approach means we always focus on what’s right for your business—not what’s popular.
Let’s shape smarter, more agile finance functions—together.

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.
