Custom software – tailored for your unique needs

Off the shelf software may be inexpensive and easy to purchase, but ultimately the total cost of ownership (TCO) can be high.  This is particularly true if you are an enterprise organisation that needs to scale, requiring streamlined operational processes for your specific business needs.

Open source innovation

The experienced development team at Catalyst create enterprise custom applications, using open source programming languages.  There’s no need for vendor lock-in or upfront licence fees, you simply pay for the features that you need to achieve the outcomes that you want.

Agile software development

We are committed to managing projects using the Agile methodology, breaking projects into a number of key phases.  As IT professionals, we collaborate closely with our clients, checking small iterations of code releases along the way.  When our clients see a concept come alive, they can then start to adjust their expectation as to the reality of what is possible.
