Why designs
stall in handoff

  1. Problem

    Devs deprioritize design polish in favour of bigger tickets.

    Implication

    Shipped product diverges from the Figma every release.

  2. Problem

    Edge cases and empty states never make it into the prototype.

    Implication

    Production UI breaks the moment real data shows up.

  3. Problem

    Design systems live in Figma, not in code.

    Implication

    Every screen rebuilt from scratch. Inconsistencies pile up.

  4. Problem

    Animation and interaction details lost in handoff.

    Implication

    The product feels cheaper than the design promised.

A design-to-code pipeline that ships 10x faster

Design tokens extracted from your Figma live in code. Every component implements the same values. No translation.

Built in layers

System first, then build, then review.

Design system in code

Tokens, primitives, and components extracted from your Figma library. The same values on both sides.

Screens built on the system

Every screen implemented on the coded system. Spacing, type, color, and motion match the Figma because they come from the same source.

Pixel-perfect, shipped fast

Agents build against the coded system at speed. Seniors review every PR against the design source. Accurate without being slow.

Case studies

F.A.Q.

Who is this for?
B2B SaaS teams with a Figma library or detailed prototypes ready to ship. Founders and product leads who want what they designed to actually reach users.
Do we need a finished design system?
No. If you have one, we follow it. If you don't, we extract tokens and primitives from your Figma and codify them. That becomes the system we build on.
What about edge cases the designer didn't draw?
They surface in the spec phase, before any code is written. Empty states, loading, errors, permissions, and copy gaps get mapped out first.
How is this different from vibe-coding with Cursor or v0?
Vibe-coding generates code from a screenshot with no design system, no spec, and no review. We extract your tokens, build against the coded system, and senior designers review every PR against the design source before anything reaches your branch.
How is this different from a traditional agency?
Agencies bill hours whether or not the work ships. We bill only for code that lands in your repo. If a change doesn't make it through review, you don't pay for it.
Who owns the code?
You do. The code lives in your repo from the moment it ships. No lock-in, no licensing strings.
Can you also handle new designs from scratch?
Yes. Pair this with our Product Design service. Senior designers craft the flows, then we implement them.
What if we already have engineers?
We plug in alongside your team.
