Before a single line of code is written, someone needs to design what the interface actually looks like. Our dedicated designer produces UI mockups for a new site or product — and because Fathom also does the engineering, the handoff into development is direct instead of getting reinterpreted by a separate agency.
01
Interface mockups for a new site or product — designed to hand off directly into a Fathom build. Priced as part of the build's design tier in the Scope Estimator, not separately.
02
If you have your own development team, we can deliver design files without the build — though the handoff is smoothest when Fathom does both.
01
What the product does, who uses it, and what it needs to accomplish — the same intake as a build, focused on the interface layer.
02
Structure first, then high-fidelity visuals — reviewed with you before anything gets built.
03
Direct handoff into a Fathom build, or exported files if your own team is building it.
Interface mockups from a dedicated designer, handed off directly into a Fathom build.
Mockups are created with the build constraints in view — component reuse, breakpoints, real content lengths — so nothing gets quietly redesigned mid-development because it turned out to be unbuildable.
Arabic mirroring is a design decision, not a CSS afterthought — which elements flip, which stay, and how bilingual text lengths affect the layout are answered before code is written.
The designer and the engineers work from the same intake — no second agency re-interpreting exported files and losing intent in the handoff.
Not every project needs a full mockup phase. For a brochure site with familiar patterns, designing directly in code against our design tiers is faster and cheaper — the patterns are proven, and a Figma detour adds cost without changing the outcome. Mockups earn their keep when the interface has many states and flows: dashboards, booking journeys, checkout funnels, anything where a wrong structural decision is expensive to discover after it is built. A few days of design iteration is much cheaper than re-engineering a shipped flow. During scoping we will tell you which side of that line your project falls on — including when the honest answer is that you do not need this service.
Yes — that is the main reason we offer UI design at all. When Fathom also builds the site, the designer and the development team work from the same brief, so what gets designed is what gets built, without a separate agency re-interpreting the files.
Yes — standalone UI mockups are available, though we cannot guarantee how faithfully another team implements them. The tightest result comes from Fathom doing both the design and the build.
UI/UX is the mockup and interface design produced by our dedicated designer, deliverable as files. Web Design is the full UX, motion, and interaction design phase done in-house by the same team that builds the platform — see the Web Design page for that.
