## A Design System Engineering Will Actually Use

Most design systems fail because they're built for designers, not for teams. We build token-first systems with the adoption model built in from day one — so the investment compounds instead of collecting dust.

## About the Service

A design system is not a Figma file. It's the shared agreement between design and engineering about how your product looks, behaves, and scales — expressed as tokens, components, documentation, and governance.

We build design systems for product teams that have outgrown ad hoc UI decisions and need infrastructure that accelerates shipping rather than bottlenecking it. That means a token architecture as the single source of truth, a component library engineers can extend without breaking, and a contribution model that doesn't require a dedicated DS team to maintain.

The result: new features ship faster, onboarding a new engineer takes hours not weeks, and your AI coding tools (Cursor, v0, Claude) produce on-brand output by default — because they finally have a system to work within.

- **Ideal For: ** — - Series A–C SaaS, fintech, or healthtech teams
- Products with 2+ designers or 5+ frontend engineers
- Teams where the same UI patterns keep getting rebuilt from scratch
- Companies preparing to scale to multiple product surfaces
- **Deliverables: ** — - Token architecture (color, typography, spacing, radius, shadow)
- Figma Variables file mirroring code tokens
- Component library (shadcn/Radix foundation + custom brand layer)
- Tailwind config as single source of truth
- Component documentation with usage guidelines
- Contribution model and governance recommendations
- Design-to-code handoff protocol
- Adoption metrics framework
- **Timeline: 4–10 weeks depending on scope and team size** — 

## Our Proven Workflow

We start with what exists, not with what should exist. Each phase has a clear output that design and engineering sign off on together.

1. **Audit & Inventory** — We review your current Figma files, codebase, and component usage to map what exists — explicit and implicit. We identify the patterns worth extracting, the inconsistencies worth resolving, and the components that engineers actually build from.
2. **Token Architecture** — We define your visual language as a structured token file: semantic color tokens, a type scale, a spacing system, and motion values. This becomes the single source of truth that design and engineering reference — not two separate systems that drift apart.
3. **Figma Variables Setup** — We build the token structure in Figma Variables so designers work with the same values that ship in code. Every component, frame, and prototype references real tokens — which means design reviews reflect production reality.
4. **Component Library Build** — We build the core component set on an open-source foundation (shadcn/ui, Radix, or Mantine depending on your stack) — extending it with your brand layer. Components are accessible, composable, and documented with variant logic that engineering can extend without breaking the system.
5. **Documentation & Contribution Model** — We document the system at the level of use, not completeness. Usage guidelines, decision rationale, and a contribution process so product teams can add to the system without waiting on a central DS team. The goal is ingredients, not gate-keeping.
6. **Handoff & Adoption Support** — We don't ship a Figma file and disappear. We run a handoff session with design and engineering together, establish adoption metrics, and define the ownership model for the next 6–12 months. A design system that nobody adopts is a Figma library that nobody opens. Related: Do You Actually Need a Design System? · How to Conduct a UX Audit

## Why Partnering With Us Drives Better Results

We build design systems that teams actually use — grounded in how design and engineering collaborate in practice, not in how they're supposed to collaborate in theory.

- **Reason 1** — We build for adoption, not for awards A beautiful system nobody uses is a Figma library that collects dust. We design contribution models and documentation alongside the components — so the system grows with the team instead of becoming a bottleneck.
- **Reason 2** — Token-first architecture We start with tokens, not components. Your visual language as a structured, semantic system — the single source of truth that design and engineering share. Everything else is derived from it.
- **Reason 3** — Engineering-ready from day one Our component libraries are built on proven open-source foundations (shadcn/ui, Radix, Mantine) and delivered as code you own and can modify — not locked inside a tool or dependent on us to maintain.
- **Reason 4** — AI-ready infrastructure A token file and named component set makes your AI coding tools materially more effective. Cursor and v0 produce on-brand output when they have a system to work within. We build the constraint layer that makes AI-assisted development consistent.
- **Reason 5** — Right-sized for your stage We don't build Shopify Polaris for a 15-person team. The scope matches your stage: a lean token layer and core component set for Series A, a full governance model for Series B+. No over-engineering, no premature complexity.
- **Reason 6** — Vertical expertise We've built design systems for fintech, healthtech, and SaaS products — industries where consistency isn't aesthetic preference, it's a trust and compliance requirement. We understand the constraints your product operates within.

## FAQ

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

A component library is the artifact — buttons, inputs, and layouts in code or Figma. A design system is everything around it: the tokens that define your visual language, the documentation that explains decisions, the governance that keeps it consistent, and the shared mental model between design and engineering. We build both — but we start with the system, not the components.

**How long does it take to build a design system?**

A lean MVP system — token architecture, Figma Variables, and a core component set — typically takes 4–6 weeks. A full system with documentation, contribution governance, and Storybook coverage takes 8–10 weeks. Timeline depends on your stack, existing codebase, and how much of the visual language is already defined.

**Do you work with our existing codebase and Figma files?**

Yes. We start with an audit of what exists — existing components, Figma files, and code patterns — and build on top of it where possible. A greenfield system is the exception; most teams have something we can extend rather than replace.

**We already have a Figma component library. Do we need this?**

It depends on whether engineering uses it. If your Figma library and your codebase have drifted — different values, different component names, different variants — then you have two systems, not one. The token architecture and the contribution model are what close that gap.

**What tech stack do you work with?**

We build on React with Tailwind CSS as the token layer and shadcn/ui or Radix as the component foundation — the dominant stack for modern web products. If your team uses a different framework (Vue, Angular, Flutter), we adapt the token architecture and documentation approach accordingly.

**Will our engineers actually adopt it?**

That's the right question, and the one most design system projects skip. We involve engineering from the audit phase — not the handoff phase. The contribution model, naming conventions, and documentation format are designed around how your engineers actually work, not how design system purists say they should.

**Do we need a dedicated design system team to maintain it?**

Not at the start. We build systems with a part-time owner model in mind: a senior engineer or lead designer who spends 10–20% of their time curating contributions. A dedicated DS team becomes necessary at 3+ product teams. We'll tell you honestly when you're at that stage.

**Can you help us rebuild a failed design system?**

Yes, and it's one of the most common engagements we do. Failed systems usually have one of two problems: the token layer was never established (so everything is hardcoded), or the adoption model was missing (so product teams bypassed it). We audit what exists, identify the root cause, and rebuild from there.

**How does this work if we're using AI tools to build our product?**

It makes the system more valuable, not less. AI coding tools like Cursor, Claude, and v0 generate inconsistent UI without defined constraints — different colors, spacing, and radius on every generation. Your Tailwind config with brand tokens and your named component set becomes the context that makes AI output consistent and on-brand. Read more.

**What does a design system engagement cost?**

Scope and pricing depend on your team size, existing codebase, and the level of governance you need. We scope every engagement after an initial call — typically 30 minutes is enough to give you a realistic range.
