Quick answer

What does a UI and UX design company do?

A UI and UX design company researches how people use a product, designs the flows and screens, tests prototypes with real users and delivers a design system for developers. Stack18's design team in Jaipur designs apps and business software and works closely with its engineers so designs ship as drawn.

FAQ

UI and UX Design questions.

Ask us anything
Do you design for web and mobile?

Yes, both, including complex business software and dashboards.

Can you redesign an existing product?

Yes. We audit it, find the biggest issues and redesign in priority order.

Do you test designs with users?

Yes. Prototypes are tested before development to reduce rework.

Do design and development happen together?

Yes. Designers and engineers work in the same team.

Can we hire design only?

Yes. Design is available as a standalone engagement.

How much does UI and UX design cost?

Every engagement starts with a fixed-price Discovery Sprint that produces scope, a plan and a quote. Custom work is quoted at a fixed price once the scope is clear. Changes are agreed in writing before they are built, so the price you approve is the price you pay.

How do you measure success for UI and UX design?

In week one we agree a baseline for task completion rate, onboarding completion and support queries. We report them at every weekly demo and review them against the baseline 30 days after go-live, so results are measured rather than assumed.

What should we prepare before the first call?

Bring a short description of how UI and UX design works today, examples of the documents or screens your team uses, and the three numbers that matter most to you. A senior specialist will use them to outline a first step and a fixed price.
