The hidden cost of
design inconsistency

  1. Problem

    UI looks different across sections.

    Implication

    Product looks unfinished and user trust drops.

  2. Problem

    Design and dev handoff is broken and full of back and forth.

    Implication

    Shipping slows. Design reviews loop. UX debt accumulates.

  3. Problem

    New team members struggle to ramp up. No single source of truth.

    Implication

    Onboarding stretches into weeks of learning unwritten patterns.

  4. Problem

    Design debt compounds.

    Implication

    Every release is slower.

A design system that helps your team ship faster

We build design systems that cut rework, speed up handoff, and keep the product consistent as it grows.

The result is a faster design process and a more reliable dev workflow.

What we can do for you

From scattered UI to a design system your team can rely on

Audit & system foundation

We review your current UI and identify inconsistencies. Then we define the tokens, patterns, and structure your product needs.

Component library creation

We build your core components in Figma. Right variants, states, naming, and reusable rules for real product work.

Tokens, guidelines, docs

We set up colors, spacing, typography, and usage rules. Designers and developers share the same source of truth.

Handoff & training

We align the system with your codebase, support implementation, and train your team so adoption sticks.

Why teams choose Donux

...and not generic product design agencies or freelancers

Experience

10+ years building products. 80+ SaaS companies. 15+ products launched. We know what works.

SaaS specialization

We focus on B2B SaaS and PLG. Complex flows, product analytics, feature adoption. This is our daily work.

Product mindset

Pretty screens don't matter if they don't solve problems. Like a PM, we balance desirability, feasibility, and viability.

Every startup stage

We've worked with companies from first customers to rapid growth. Our decisions are backed by what we learned on those projects.

How we build your design system in 4 steps

Typical engagement: 6 to 8 weeks for a complete build.

Design system discovery and foundation

1. Discovery & Foundation

We audit your current design patterns and talk to your team. Then we establish your design language: colors, typography, spacing, and component structure.

Component library build

2. Component Build

We design and document your core components. Buttons, inputs, modals, cards, navigation, with the right variants and states.

Implementation and testing

3. Implementation & Testing

We set up design tokens and sync Figma with your dev tools. Then we test the system with your team and refine on feedback.

Design system handoff and training

4. Handoff & Training

We train your team and set maintenance practices. We hand over full ownership so you're not dependent on us for updates.

F.A.Q.

Do you build the design system in Figma only, or also in code?
We build the Figma library and design tokens. Code implementation (React, Vue, etc.) is handled by your dev team. We provide clear guidance and keep Figma and code in sync.
How long does a design system take to build?
A typical engagement is 6 to 8 weeks. It depends on product complexity and component count. We can also do a quick foundation in 2 to 3 weeks and expand over time.
What if we already have a design system that's broken or outdated?
We audit what you have, clean it up, and rebuild it the right way. It's often faster than starting from scratch. We learn from your existing patterns.
Can the design system grow with our product?
Yes. That's the whole point. We set up the system so your team can add components, patterns, and tokens as your product evolves. We also provide a maintenance playbook.
What happens after we launch the design system?
We hand over full ownership and provide training. You're not dependent on us for updates or maintenance. We stay available for ongoing support if needed.
Do you work with our developers to ensure integration?
Yes. We work closely with your dev team during implementation. Smooth handoff, design tokens set up correctly for your tech stack.
Can I build my design system through Magic Team?
Yes! Magic Team is a managed team of AI agents and senior humans that ships real code. Connect your repo and get features, MVPs, or bug fixes delivered as PRs, reviewed by Donux senior designers and developers.
