About Zeller

Accepting payments, managing your finances, and paying recipients should be simple. Unfortunately, this isn’t always the case. Finding integrated financial solutions to help your business thrive often requires you to weave together multiple products from different providers. While a small group of large enterprises enjoy the privilege of financial solutions tailored for their specific needs, the vast majority of Australian businesses are underserved due to a lack of innovation, disparate providers, opaque pricing, and restrictive contracts. 

We believe in a level playing field where all businesses benefit from access to smarter payments technology and integrated financial services that enables them to accelerate their cash flow. So we’re hard at work building the tools to accomplish this. 

Zeller is backed by leading VCs, and brings together a team of experienced payment and tech industry professionals who are aiming to redefine business banking and financial services for Australian businesses. With an exciting roadmap of innovative new products under development, we are building a high performing team to take on the incumbents.

If you are passionate about innovation, thrive in fast-moving environments, love a challenge, hate bureaucracy and can’t think of anything more exciting than disrupting the banks, we’re putting together a team you might want to join.
