Challenges

You're here because you need to
visualize your idea, right?

Is your concept feasible?

A mockup prototype lets businesses test product viability and gather feedback before full development. By creating a functional representation, companies can spot design flaws, test usability, and make early improvements, saving time and resources.

Worried about the cost of development?

An MVP prototype helps cut costs by testing and refining key features early, ensuring your product meets user needs and saves time and resources.

Do you need a more effective way to communicate your vision?

A UI prototype visually represents a product's design and functionality, offering stakeholders and investors a clear vision of how the final product will look and work, helping align expectations, and gathering valuable feedback.

INSIDE OUR DESIGN PROTOTYPE PROCESS

Testing ideas with users before committing to full development

Building a full product based on assumptions is expensive. Prototypes let you test core flows, validate design decisions, and gather user feedback before developers write a single line of code. You find out what works and what doesn't when changes are still cheap to make.

Stakeholder interview

Defining what needs to be tested and why

We identify which user flows and features need validation. Is it the onboarding experience? A complex workflow? A new interaction pattern? The prototype focuses on the parts where you need feedback, not building every screen.

Key steps:

Core flows and features to prototype
Key assumptions and questions to validate
Target users for testing
Success criteria and metrics

Deliverables

Prototype scope document testing plan

Competitor & trends analysis

Understanding patterns and user expectations

We analyze how competitors and industry leaders handle similar flows to better understand what users expect and where you can differentiate. We also review relevant UX patterns and usability principles.

Key steps:

Competitor flow analysis
Industry pattern research
Best practice benchmarking
Differentiation opportunities

Deliverables

Research summary pattern library

High-level architecture

Structuring content and navigation for exceptional user experience

We map out how information is organized, how users navigate between sections, and where key actions live. This structural work happens before visual design so we’re not distracted by aesthetics when testing flow logic.

Key steps:

Site map or app structure
Navigation hierarchy
Content organization
User flow diagrams

Deliverables

Information architecture diagram flow maps

Visual direction

Establishing the look and feel

We create mood boards and style explorations to set the visual direction. Colour palette, typography, component style, overall aesthetic. This gets approved before we design dozens of screens, preventing late-stage visual overhauls.

Key steps:

Mood boards and style references
Colour and typography exploration
UI component concepts
Brand alignment review

Deliverables

Visual direction deck style tile

Prototype UI/UX design

Building and testing the experience

We design the key screens and connect them into a clickable prototype. Then we run usability tests with target users, watching how they interact with it, where they get confused, and what works well.

Key steps:

High-fidelity screen design
Interactive prototype build
Usability testing sessions
Iteration based on findings

Deliverables

Clickable prototype usability test report refined designs

Design handoff

Preparing assets for implementation

We polish the prototype based on test results and prepare everything developers need: final screen designs, component specs, interaction details, and UI kit documentation.

Key steps:

Production-ready screen designs
Design specifications and annotations
Component library and UI kit
Developer handoff documentation

Deliverables

Final prototype UI kit implementation specs

FAQ

Questions already
answered

What is a design prototype?

A design prototype is an early, interactive model that represents a product’s core functionality and user experience before full development. It helps validate design concepts, identify usability issues, and streamline the development process. Whether you’re building a mockup prototype or an MVP prototype, this step ensures your idea is viable and ready for refinement.
A design prototype is an interactive model that helps validate product concepts before full-scale development.

Why do I need prototyping?

Prototyping is essential in product prototype design as it allows you to test and validate ideas before investing in full-scale development. A well-executed prototype can attract investors, reduce costly revisions, and improve user engagement. With an MVP prototype, you can efficiently test core features and ensure a market fit before expanding development. A product prototype design helps reduce risk, optimize user experience, and attract investors before committing to costly development.

How long does it take to create a design prototype, and how much does it cost?

The duration varies depending on the complexity and fidelity of the prototype. A basic UI prototype can take just a few days, while a detailed UX design prototype with multiple screens and interactions may take several weeks. For projects requiring extensive validation, an MVP prototype can extend into months, ensuring functionality and user experience are optimized before launch. The price of a design prototype depends on factors such as the number of screens, level of detail, and required interactions, which usually start from $3.500. Our prototype agency offers tailored pricing to fit different needs, ensuring a balance between affordability and high-quality execution.

What tools do you use for prototyping?

We primarily use Figma for UI design prototype creation, offering a collaborative and efficient design workflow. For interactive elements and prototype web design, we may incorporate additional tools to enhance the prototype’s presentation and usability. We use Figma for UI design prototype creation and may integrate additional tools as needed.

Can I use the prototype for investor pitches?

Absolutely! Our UI prototype services ensure that your product is presented in a compelling, interactive format. Investors appreciate tangible demonstrations of product potential, and a well-structured product prototype design significantly increases your chances of securing funding.

What happens after the prototype is ready?

Once your UX design prototype is finalized, you have several options: proceed to full development, conduct user testing, or refine the design based on feedback. Our prototype agency can assist in the next steps, including prototype web design, MVP development, and setting up a scalable design system.

How to embed a Figma prototype in a website?

To embed a Figma prototype in a website, you can generate an embed link directly from Figma. This allows stakeholders and users to interact with the prototype without leaving the page. Our prototype agency can assist with seamless integration, ensuring your UX design prototype is presented effectively for investor pitches or user testing.
