Why choose us?

AI has made custom software affordable
Custom systems used to cost hundreds of thousands of dollars. Now, with the help of AI, we can build custom systems in a fraction of the time and cost.
Get exactly what you need
We'll build you exactly what you want and make sure it works exactly the way you want. No confusing setups, no annoying workarounds, no going around in circles with non-technical salespeople to try get a problem solved.
World class skills
We’ve built apps used by hundreds of thousands of people and keep close ties to Silicon Valley. We use the same tools as the world’s top tech companies.
End to end service
We’ll guide you from the planning stage, all the way through to design, delivery, testing, and ongoing improvement. When you need help or support you'll talk directly with the person who wrote the code.

How we work

1. Introduction call
We'll ask all sorts of questions to get an idea of your business and uncover any potential areas where we can help. If we see an opportunity, we'll ask you to explain the important parts of that process and the specific challenges and needs you have.
2. Scope planning meeting
If we both see an opportunity to work together, we'll drop by in person to talk more about the project and talk to any key stakeholders to get a better understanding of the scope and requirements.
3. Formal proposal
We'll send you a detailed proposal with scope, cost and timeline breakdowns. This will cover the goals, requirements, user experience, user interfaces and technical specs. If you're happy to proceed, we'll sign a contract and get started.
4. Active software development
We’ll build out your software system to be “feature complete” and allow continuous testing as early as possible - this allows us to get feedback and adapt quickly.
5. Acceptance testing
We’ll go live and test the system with real data and real users. We’ll fix any bugs and make any changes you need. We’ll also provide training and support to make sure everyone is comfortable with the new system.
6. Long-term stable support
Once everything is running smoothly, we’ll continue to sort out the hosting, maintenance, performance monitoring, fix any bugs and provide technical support.

Who are we?

Zeltta was started in 2020 in Hamilton, New Zealand by Rikus Wiehahn. The initial focus was on digital product development but over time we have come to admire and enjoy working with the companies that form the bedrock of society. Rikus still does the majority of the work but he brings in external contractors when some extra hands are needed.

The biggest risk with custom software is building something that nobody needs. We try to mitigate this risk by seeking early and constant user feedback and re-prioritising our roadmap to ensure we're always focused on the most important things.
