What’s included

Everything, end to end.

Research, design systems and prototypes. One senior team takes it from the first call to production.

  • Product research

    Interviews, current-flow analysis, and benchmarking so you decide with evidence, not opinions.

  • Design system

    Tokens, components, and documented rules that keep things consistent as the product grows.

  • High-fidelity prototypes

    Navigable Figma screens with real states and interactions to validate before any code is written.

  • WCAG accessibility

    Contrast, focus, hierarchy, and keyboard nav built into the design, not patched on later.

  • Build-ready handoff

    Specs, measurements, and assets handed off so engineering implements without guessing.

  • UI shipped in code

    If we build it, the design lands as real components in your repo, faithful to the prototype.

How we do it

    System and prototypes

    We build the design system and high-fidelity prototypes, iterating with you every week.

  4. 04

    Handoff or build

    We deliver build-ready specs, or take it to code in your repo. Your call.

Questions

What people ask us.

How much does the design cost?

Fixed price per phase, set at the end of Discovery. A design Phase 1 — short research plus a hi-fi clickable prototype — starts at USD 2,000. You know the cost before we start, with no surprises by the hour or per revision.

Who owns the design files?

Yours. The Figma files, the design system, and every asset live in your accounts from day one. No lock-in to us.

Will the design be buildable as-is?

Yes. We design around real components, states, and tokens, so the handoff is direct. If we build it, it lands in your repo identical to the prototype.

Do you only design, or also build it?

Both. We design, build, and operate. You can stop at handoff or continue with us until the UI is in production, without switching teams.

Let’s build it together.
