Why the Zebra?

Black & white simplicity.
In a complex market, full of over-engineered solutions.

Simplicity is the ultimate sophistication.

- Leonardo da Vinci

EDT is a privately owned software company founded in 2002 in Australia. Over two decades the company has expanded internationally, focussing on the development of robust, scalable software to manage eDiscovery, litigation and investigations. EDT headquarters are in New York City and our team 'hubs' are in the UK and Australia. We are proud to be one of the only international woman owned businesses in our sector.

The EDT team comprises lawyers, software engineers and forensic experts who are committed to a core software design philosophy; Simplicity.  This ensures our software is easy to use, avoiding complexity and over-engineering.  We collaborate with leading edge litigation support technologists, service provider partners, forensic experts and investigators from within our client base to ensure our solution continues to meet their evolving needs.

Over the last decade, EDT has grown to be trusted by an international blue-chip client base including regulators, law & accounting firms, corporations, government agencies, forensic experts and consulting service providers. We are experiencing considerable growth due to our unique value propositions - simplicity, adaptability and complete end-to-end functionality.  

Why the Zebra?


We are often asked this question about, Mr Z, our corporate symbol.  The short answer is, well, we just like him.  Seriously though, we think eDiscovery has burdened the litigation process by becoming unnecessarily complicated. Prevailing software solutions are over-engineered, heavy and expensive and too many disputes involve runaway discovery costs and are fought as digital wars of attrition rather than on the merits.

We chose Mr Z because he symbolizes clarity, adaptability, differentiation and black and white simplicity.  These themes resonate for us because they are not only design tenets for our software, they are also attributes we think firms will need to succeed in the future and we are delighted to work with our clients to help them to do just that. 

Our leadership team has over 100 years of legal technology experience.
