We partner with digital agencies and organizations that need tech that delivers. When the stakes are high and you can't afford to get it wrong – that's exactly when we shine brightest.

Your Tech Partner
Zeltta was founded in 2020 by Rikus Wiehahn. We don't work with everyone - we work with the obsessed ones. The entrepreneurs who can't sleep because they've glimpsed a better way. The owner-operators who see broken systems and refuse to accept the status quo. These are people who don't just want to build an app - they're on a mission to transform how things work, and they need a technical partner who gets it.
As Director, Rikus brings over a decade of software engineering expertise to every project, personally overseeing development while bringing in specialized contractors when additional expertise is needed. This hands-on approach ensures exceptional quality and clear communication throughout the process.
We understand the pressure you face to deliver exceptional solutions. Our commitment to quality, attention to detail, and transparent collaboration ensure we don't just meet expectations – we exceed them.

Common Questions
Straight answers to the questions we hear most often
How much will my project cost?
Most projects run around $20,000 to build and $500 monthly for support. But every project is unique – we'll give you a clear estimate once we understand what you need.
How long will my project take?
On average, about two months from start to finish. The timeline depends on what we're building. We'll map out a clear timeline during our first conversation.
What is your hourly rate?
We use a rate of $150/hour (ex GST) when planning projects. But we charge a fixed cost for the actual work – no surprise bills or unexpected costs.
Do I have to pay a deposit?
Yes, we ask for 30% of the project cost upfront when we start working together. The remaining 70% is only due when we've completed the project.
