A Design System Your Engineers Reach For
Tokens, components and written rules that your engineers, Figma MCP and coding agents all read from the same source.
Trusted by funded B2B SaaS teams






Case Studies
A few of the products we've shaped.
PROJECTS
From audit to adoption
We start with what exists in your Figma and your codebase. Each phase ends in an output that design and engineering sign off together.

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 your engineers build from.
Typical outputs:
A map of what exists, in Figma and in code
The patterns worth keeping
The duplicates costing you rework
A Design System Readiness baseline
What you get
Tokens, components and written rules in one source, sized for the team you have now. Scoped so your engineers adopt it in the sprint after handoff.

A token architecture
Semantic colour, a type scale, spacing and motion as a structured token file your designers and your code both read.
Change a token and it propagates on the next build, in Figma and in code.

Figma Variables wired to it
The token structure built in Figma Variables, so a designer picks the value that ships instead of a value that resembles it.
Themes and modes stop being a redraw.

A component library in your stack
The core set built on an open-source foundation your engineers already trust, extended with your patterns.
Chosen against your codebase.

Rules an agent can read
Named components, a token file and written rules in the formats Cursor, Claude Code and Figma MCP consume.
The difference between an agent guessing and an agent knowing.

Documentation at the level of use
When to reach for a component, why it works that way, and how a product team adds the next one.
Short enough that people read it during a sprint.

An adoption plan and a score
A handoff session with design and engineering together, adoption metrics agreed, and a Design System Readiness score to measure against.
So you can tell in a quarter whether it took.
The right design support for where your product is now.
From focused MVP improvements to full redesigns, design systems, and ongoing product design support.
A new product or module
For teams turning an idea, an internal prototype or a rough MVP into something real users can trust.
New B2B SaaS products
AI features and agent workflows
Investor-ready product stories
A first design system
Founder-led MVPs
Prototypes that need a production path
An existing product
For teams with a live product that grew feature by feature and now feels inconsistent or harder to use than it should be.
SaaS dashboards
B2B platforms and admin tools
Complex workflows and data tables
Onboarding and activation
Fintech and healthtech compliance flows
Design debt cleanup
Ongoing product work
For teams that need senior design every sprint without hiring, or a design lead one or two days a week.
Fast-moving product teams
Engineering-led teams with no designer
Roadmap and feature support
Design system stewardship
Activation and adoption work
Design leadership and hiring
Industries We Work With
B2B SaaS first, with most of our work in fintech, healthtech and AI products.
Fintech
AI finance, fintech SaaS and B2B financial tools. Trust, density and compliance in the same screen.
Healthtech
Healthtech SaaS and compliance platforms, designed under HIPAA and OSHA constraints.
SaaS
B2B products moving upmarket, with design debt to pay down before the next release.
AI & ML
AI features that have to survive an enterprise demo: uncertainty, corrections, audit trail, failure states.
Why these systems get used
Most design systems fail on adoption. Everything below is built around the day your engineers reach for it.
- We build for adoption
- 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.
- Tokens come before components
- Tokens come first. Your visual language as a structured, semantic system: the single source of truth that design and engineering share. Everything else is derived from it.
- 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.
- Ready for your AI tooling
- A token file and named component set makes your AI coding tools 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.
- Sized for your stage
- A fifteen-person team does not need Shopify Polaris. Series A gets a lean token layer and the core components; Series B gets the governance model on top.
- Built in regulated verticals
- We have built design systems for fintech, healthtech and SaaS products, where consistency carries a trust and compliance load. We know the constraints your product works inside.
