Designing digital experiences that feel effortless.
Great digital products do more than look good. They simplify complex tasks and guide users intuitively. We create streamlined, elegant experiences that delight users and deliver measurable impact.
About the service
At Rocket Lab, we bring design expertise combined with a user-first mindset. Whether you are launching a new product, refreshing an existing experience or advancing a platform for scale, we prioritise intuitive designs that support both your users' needs and your long-term goals.

What we offer
User research and discovery
We begin with user interviews, testing and behavioural insights to fuel purposeful design decisions.
UX strategy and flow mapping
Clear, efficient user journeys designed to reduce friction and boost engagement.
Wireframes and prototyping
From sketches to interactive prototypes, we validate assumptions early so you can move forward with confidence.
High-fidelity UI and visual design
Polished, accessible interfaces that reflect your brand and delight your users.
Design systems and style guides
Reusable design components and guidelines that keep your product consistent as it grows.
Design and development collaboration
Designers working side by side with engineers to ensure pixel-perfect implementation and practical interaction.
Design is the first paid step of a build
Most of our builds start with design. A short, paid design phase turns your idea or brief into user flows, a tested prototype and high-fidelity screens before anyone writes code, so the build is quoted from a design rather than a guess.
The designers and engineers work as one team, so the design carries straight into the build: the same people, the same flows, and no gap at handover.
- A prototype your users and stakeholders can try before any code is written
- A fixed quote for the build, based on the designs
- A design system your engineers build from
Before You Buy's platform started with 2 months of wireframing, design thinking and architecture, then a 9-month build from scratch.
App design work
Apps we have designed
Four projects from our case studies where design came first.
WeView
We turned the founder's idea into a fully designed digital ecosystem, mapped end to end across mobile and web. The design phase took six weeks.
Exetel
UX and UI, brand, app design and website design for an Australian internet and mobile provider, and the build of the previous version of its app.
Before You Buy
The whole platform, designed and built from scratch: the public website, the customer portal, the admin, BYB Assist for agents and the BYB Inspector app for iOS and Android.
MyGig
The MyGig app for iOS and Android, designed and built in Flutter. Casual workers find shifts, see the pay up front, clock in and out and track what they earn.
Our design process
Six steps from understanding your users to an experience that keeps improving after launch.
Discover and align
We explore your objectives, users and challenges to define what success means.
Plan and map
We craft user flows, wireframes and information architecture that lay the groundwork for clarity.
Design and prototype
We develop high-fidelity designs and interactive experiences that bring your vision to life.
Test and refine
We validate ideas with real users, gather feedback and iterate for usability and impact.
Handover and support
We provide development-ready assets, documentation and ongoing support for a smooth implementation.
Evolve and optimise
We track performance, gather user insights and keep refining the experience as new needs and opportunities appear.
