Our History and Future

“Zetta commenced business over 16 years ago, delivering specialist infrastructure services to Woodside and Western Mining with a small group of consultants. Since then, we’ve grown steadily adding a range of infrastructure services capabilities and delivery options. We’ve seen the introduction of cloud computing and the growing importance of security and have been at the forefront of development in these areas to ensure that we continue to support our customers. We still love tech and now have the opportunity with a bigger team to have a broader business impact.

We started with the idea of creating a company that we’d all like to work in. We’re pleased over the years to have seen the careers of many professionals blossom and some have moved to other great opportunities of which we are very proud.

Over the coming year(s) we are focused on growing our footprint further in Perth by adding to our core capabilities, by partnering with a number of specialist organisations and by our community contributions.”

– Nathan Harman, CEO
