A design system is the single source of truth for how your product looks, feels, and behaves. When it's built well, designers stop recreating components from scratch, engineers stop translating vague specs into code, and the entire product team moves faster. We build design systems that are actually used: grounded in your existing product, documented for your team, and structured to grow with your codebase.

A design system is infrastructure - it either accelerates everything or it blocks everything

Most teams feel a missing design system before they can name it. Designers rebuild the same button in five files. Engineers make calls that should have been design decisions. It isn't anyone's fault; it's a systems problem.

Your design and engineering teams are solving the same problems independently.

When designers and engineers don't share a component library, both sides make the same decisions separately. One dropdown in Figma, a different one in code, and nobody owns either. A design system gives both sides one source of truth.

Your product is visually inconsistent across surfaces.

Buttons that change size between pages, spacing that's off on mobile, one pattern with three treatments. Users feel the friction even when they can't name it. A design system fixes consistency at the source, so new features inherit it automatically.

Your system is designed for today's codebase, not tomorrow's AI-assisted development.

When engineers generate UI with AI tools, your component library and tokens become the spec those tools work from. A clear token layer for spacing, color, and type keeps AI output consistent. Systems built without one will need rebuilding.
A structured evaluation of your existing component library, token architecture, documentation, and adoption patterns - identifying what's working, what's inconsistent, what's missing, and where the highest-leverage improvements are. Audit findings become the foundation for a focused build or refactor plan
A production-ready component library built in Figma, your front-end framework of choice (React, Vue, Svelte, Web Components), or both - covering the core UI patterns your product uses most, with documented variants, states, and usage guidelines
A structured token system for color, typography, spacing, elevation, and motion - built as the foundation beneath your component library so visual decisions can be updated globally rather than component-by-component. Token architecture is what makes a design system scalable and AI-development-compatible
A design system is only as useful as its documentation. We build usage guidelines, contribution workflows, and decision frameworks that make adoption the path of least resistance - so your team reaches for the system first instead of building around it
Design systems drift without active stewardship. We offer ongoing maintenance retainers that keep your component library and token architecture in sync with your evolving product - adding new patterns, deprecating outdated components, and ensuring documentation stays current as your team grows
Close the gap between design and engineering with structured handoff workflows, auto-layout conventions, and component naming systems that reduce implementation ambiguity and give engineers the context they need to build accurately without a synchronous review meeting for every component
We start by understanding what you already have. We audit your existing components, tokens, documentation, and adoption patterns - talking to the designers and engineers who use the system day-to-day to understand where it's working and where it's breaking down. If you're starting from scratch, we inventory your product's UI patterns to understand the scope of what needs to be systematized. The audit gives us a baseline and a prioritized build plan before we write a line of code or create a single component.
We define the token architecture, component hierarchy, naming conventions, and tooling decisions that will govern the system. This includes decisions about how the design system connects to your codebase, how tokens are structured across platforms, and how the Figma library maps to code components. These decisions are harder to change later than the components themselves - we take the time to get them right before building begins.
We build the foundational layer: design tokens, base styles, and the core components that appear most frequently across your product. We work iteratively, shipping components for team review before moving forward, and we build in Figma and code in parallel so handoff friction is eliminated by design rather than resolved after the fact.
With the foundation in place, we expand the system to cover the full range of UI patterns your product uses - complex components, responsive variants, interaction states, and edge cases. We refine based on feedback from the designers and engineers using the system in active feature work, not just reviewing components in isolation.
We document every component with usage guidelines, do's and don'ts, code snippets, and accessibility notes - structured for the team that will maintain it, not just the team that will read it once. We run a handoff session with your design and engineering leads to walk through contribution workflows, version control conventions, and the governance model for how the system evolves over time.

Design system FAQ

What's the difference between a design system and a component library?

A component library is part of a design system - it's the collection of reusable UI components (buttons, inputs, cards, modals) that designers and engineers build from. A design system is the broader system that governs how those components are built, including the design token layer (color, typography, spacing values), documentation and usage guidelines, contribution workflows, and the governance model that keeps it maintained over time. A component library without the surrounding system tends to drift and fragment. A design system without a well-built component library is documentation with nothing to document.

Do you build design systems in Figma, code, or both?

Both, built in parallel. A design system that lives only in Figma creates handoff friction - engineers are still translating design decisions into code independently. A system that lives only in code gives designers nothing to work from. We build in Figma and your front-end framework simultaneously, so the component library and the code implementation are aligned from day one rather than synchronized after the fact.

How long does a design system build take?

A foundational design system - core tokens, base component library, and documentation - typically takes 8-12 weeks. Complex systems for large products or multi-platform applications run longer. We scope the engagement based on the size of your UI pattern inventory, the state of your existing codebase, and how many surfaces the system needs to cover. We also offer a phased approach: build the foundation first, expand iteratively as the system is adopted.

Can you work with our existing design system instead of starting from scratch?

Yes - and often that's the right approach. We start with an audit of what exists: what's being used, what's drifted from spec, what's missing, and what's causing the most friction for your team. In many cases, a focused refactor of an existing system is faster and less disruptive than a ground-up rebuild. We recommend starting fresh only when the existing system's architecture is fundamentally misaligned with where the product is heading.

How does a design system connect to AI-assisted development?

AI coding tools generate better output when they have structured context to work from. A design system with a well-defined token architecture - named color scales, spacing units, typography styles - gives AI tools the vocabulary to generate consistent UI code without requiring constant correction. Component documentation with usage guidelines and variant specifications gives AI tools the constraints they need to produce accurate implementations. Design systems built without this structure will need to be retrofitted when your team adopts AI development workflows.

What should we ask an agency before a design system audit?

Ask whether they audit both Figma and code, since drift usually lives between the two; whether they talk to the designers and engineers who use the system daily; what the audit produces (a prioritized refactor plan, not just a list of inconsistencies); and whether they can do the cleanup or only recommend it.

Who maintains the design system after you hand it off?

That depends on your team's capacity and how actively the system needs to evolve. For teams with an in-house designer or front-end engineer who can own it, we structure the handoff to set them up for success - with contribution workflows, versioning conventions, and documentation that makes maintenance tractable. For teams without that capacity, we offer ongoing maintenance retainers that keep the system current as the product evolves. We're explicit about what a system needs to stay healthy so you can make an informed decision about which path fits your team.

Do design systems work for small teams?

Yes - and often they matter more for small teams than large ones. A five-person product team can't afford the overhead of resolving design-engineering ambiguity on every feature. A well-scoped design system eliminates the class of decisions that don't need to be made repeatedly, which compounds quickly when your team is small and every sprint hour matters. We scope design systems to team size and product complexity - a small team doesn't need a system built for a 50-person org.
