What our clients say about Mountalis

I have worked with external engineering teams before and the difference with Mountalis was the level of ownership. They didn't wait for every detail to be defined. They investigated the problem, proposed solutions and knew when to involve our team. I'd have no hesitation working together again on future products.

Stefan T. / Chief Innovation Officer

I think one of the reasons the engagement worked well was that Mountalis never separated product from engineering. We could discuss the user journey and five minutes later be talking through the architecture. It always felt like everyone was working towards the same outcome.

FAQs

  • We test the design with real users before any build begins. Working prototypes show how people move through the product so we can confirm it solves the right problem. This protects your investment by catching problems early when they cost little to fix.
  • Yes. We first assess the existing product to identify usability issues, friction points and opportunities to improve the interface. The work focuses on what should change and what should remain stable so the product becomes easier to use without losing what already works.
  • We prepare designs with responsive layouts, defined states and clear implementation details. Components, assets and interaction notes are organized so engineers can build without unnecessary interpretation. This helps move from design to development with fewer gaps and fewer rework cycles.
  • Yes. We can lead the design work or join your existing product team. Responsibilities are defined early so designers, engineers and stakeholders know how decisions are made. This keeps collaboration clear without adding unnecessary process.
  • Yes. We build a design system so your interface components and rules sit in one place as a single source of truth. This keeps the product consistent for users and helps design and development move faster. Every team in your organization can reuse the system instead of building the same elements twice.
  • We study your brand standards, audience and product context before defining the visual direction. The interface should feel consistent with your identity while remaining clear and practical for users. We review key design decisions with your team so the final product reflects the brand accurately.
  • Timelines depend on product complexity and the depth of design work required. A focused redesign or audit can take several weeks while a full product design process may take a few months. We define the timeline early so research, design and review cycles are planned clearly.
  • Cost depends on the scope of the product, the number of screens and the level of research required. A focused audit or redesign is usually smaller than a full design process for a new product. Once the work is defined, we provide a clear estimate tied to the design effort involved.
