In short

What does a product design agency do?

A product design agency shapes what a digital product does and how it feels to use: researching users, mapping journeys, designing the interface and testing prototypes before code is written. Good product design cuts build cost, because problems are found on screens rather than in code.

We design products end to end — from the first discovery sprint to a polished, tested interface and a design system your team can build on. Decisions grounded in research, not taste alone.

Who it’s for

Founders pre-build, product teams whose app works but feels clunky, and anyone raising against a prototype.

Capabilities

What Product Design covers.

01

Product & UX strategy

Define what to build and why before a line of production code is written.

02

User research & testing

Talk to real users, validate assumptions, and design against evidence.

03

UI design & prototyping

High-fidelity interfaces and clickable prototypes you can test and show investors.

04

Design systems

A reusable component library so the product stays consistent as it grows.

05

Discovery & design sprints

A focused, fixed-scope week to go from problem to a testable direction.

Process

No quotes theatre. Four steps.

You get an indicative range before discovery and a fixed scope after it. Nothing about the price should be a surprise.

STEP 01

Discovery

A short, fixed-price discovery to define exactly what is being built — so there are no surprises later.

STEP 02

Fixed-scope proposal

A clear proposal broken down by phase, with an indicative range up front. You approve, adjust or stage it.

STEP 03

Build in sprints

We build in short sprints with regular demos, so you see working software early — not a big reveal in month four.

STEP 04

Launch & support

We launch, hand over clean documented code, and support it — with a retained team if you want one.

FAQ

Questions people ask.

Ask us directly
What's the difference between UI and UX design?

UX design is how a product works: the journeys, structure and decisions a user makes. UI design is how it looks: layout, type, colour and components. We do both together, because a beautiful screen that confuses people still fails.

How much does product design cost?

A focused discovery and design sprint for a new product is usually quoted as a fixed price after a free audit. Ongoing design support for a product team can be monthly. We'll recommend the smallest piece of design work that answers your biggest question.

Do you test designs with real users?

Yes. We test clickable prototypes with five to eight people from your target audience, watch where they get stuck and fix it before development starts. It's the cheapest point to change your mind.

Can you redesign an existing app or SaaS product?

Yes. We start with an audit of the current product, analytics and support tickets, find where users struggle, then redesign the worst journeys first so improvements ship quickly.

Will developers be able to build your designs?

Yes. We design in Figma with a component-based design system, document states and edge cases, and our own developers review designs before handover. If we build it too, there's no gap at all.

Do you create design systems?

Yes. We build design systems in Figma and in code: components, tokens, spacing and patterns that keep your product consistent as more people work on it.
