Build a working proof-of-concept (POC)

Requirements documents can never compare to experiencing your idea before you build it.

A proof-of-concept is a real, working version of your software idea, built fast so you can prove it before you fund the full build. Putti builds POCs for New Zealand businesses and startups in 2 to 4 weeks, using professional AI-driven development, then puts them in front of the people who will actually use them.

Before you commission a software build, you want to know that it solves the problem elegantly. A working POC gets you feedback in weeks, not months.

The gap between requirements and experience

Workshops. Requirements documents. Wireframes. By the time anything is built, the team has moved on, the process has changed, or the budget has gone. Even then, you're often guessing whether the tool will actually get used.

We think there's a better way. Build a working POC first, then let your team, your investors and your other stakeholders use it and tell you what they think. Only once you've shaped that into a product people want do you invest in the version built to go the distance.

From idea to working software, fast

We build it with you, not just for you

You bring the problem or the idea, and we work alongside you to design and build a real, functioning version of it, using modern AI-driven development, the disciplined form of what people call vibe coding. Not a mockup. Not a slide deck. Software your team, or your potential customers, can log into, use and give feedback on, well before a full production build.

Tested with real users, not hypothetical ones

A proof-of-concept only earns its name if it gets used. We help you put it in front of the people who'll actually rely on it, so you find out early what works, what's missing and what needs to change, while those decisions are still cheap to make.

Built to hand over to production, properly

A vibe-coded proof-of-concept is not production software, and we won't pretend otherwise. Once the idea is proven, our senior engineering team takes it from working demo to secure, scalable, properly maintained software, with the same rigour we bring to every custom build. Read how that handover works if you want the detail.

Not a cheap app. A serious first step.

There's no shortage of tools promising a working app in an afternoon. That is not what this is. We use vibe coding as a concept accelerator, a fast and low-risk way for New Zealand entrepreneurs and business owners to validate a new software product before committing to the full build. Behind it sits the same team that has delivered 100+ projects since 2010 with zero failures, for clients including Spark, Fletcher Building and the NZ Herald.

Is your idea worth building?

Bring us the problem or the idea and we'll help you work out, quickly and cheaply, whether a purpose-built product is worth the investment. See our work if you want to know what we do once the answer is yes.

Frequently asked questions

  • What is a proof of concept in software development?

    A proof-of-concept is a real, working version of a software idea, built quickly so people can use it and judge it before anyone funds the full build. It is not a mockup or a slide deck. Putti builds POCs for New Zealand businesses in 2 to 4 weeks, then puts them in front of the people who would rely on the finished tool.

  • How much does a proof-of-concept cost?

    Most proof-of-concept projects run between $5,000 and $15,000 NZD plus GST. Where yours sits depends on how complex the product is and how much consulting it takes to land on a solution design. That is a fraction of a production build, which is the point. You find out whether the idea is worth funding before you fund it.

  • Is a proof-of-concept the same as a finished product?

    No. It's a real, working version of your tool, built fast to prove the idea and get feedback from the people who'll use it. It won't have the security, scalability, integration depth or support processes that production software needs. That comes next, once you know the idea is worth building properly.

  • How long does a proof-of-concept take?

    Typically 2 to 4 weeks. The exact timeframe depends on scope, but speed is the whole point. Something real in front of your team quickly means you learn fast and cheaply. A requirements process that runs three months has already cost more than the POC would, and it still leaves you guessing.

  • What happens after the proof-of-concept?

    If it proves the idea, our senior engineering team takes it forward to a production-ready build that is secure, scalable and properly supported. If it doesn't, you have learned that for a fraction of the cost of a full build, and lost very little time finding out. Either answer is worth having early.

  • Who is a proof-of-concept for?

    New Zealand mid-market businesses and startups with a process, tool or software idea they want to validate before committing serious budget to it. If you're weighing a build that runs into six figures, a few weeks spent proving the concept is the cheapest risk you will ever buy down.

Have a project in mind?

We've delivered 100+ projects since 2010 with zero failures, and rescued 20+ that others couldn't finish.
