About Zeller

Australian business owners are entrepreneurial, driven and passionate individuals. Yet when they seek the merchant services they need to operate and grow their businesses, there is a distinct lack of support and transparency from the banks. Unfortunately, there has been no better alternative – until now.

At Zeller, we’re taking on the incumbents with a suite of products that redefine business banking. Our founding team broke away from some of the biggest names in banking and tech to solve the pain points millions of business owners suffer through every day: frustrating wait times, confusing contracts, hidden fees, and clunky tech, to name a few. This mission piqued the interest of renowned VCs, which led to one of the largest pre-launch funding rounds Australia has ever seen. 

After quietly working away for over a year, we publicly released Zeller on 4 May 2021 – it’s everything business owners need to accept payments, manage their finances, and pay recipients, all in one box. Now, our sights are firmly set on an exciting roadmap of new, innovative products to help Australian businesses grow even further. 

Come join us as we level the playing field for Australian businesses. Our story has just begun.
