Step 1

Kickoff & Discovery

We gather, align, and strategize in the foundation phase to create mutual understanding. We take the client's vision and prepare it for the transformative journey ahead.


Establish a solid understanding of the intended application, client aspirations, and potential challenges, and devise an actionable plan to bring this vision to life.


Knowledge Transfer

We familiarize ourselves with the existing data, prior research, and any other foundational material the client provides. Understanding the terrain before embarking on the journey is essential.

Stakeholder Interviews

Engaging one-on-one with key stakeholders clarifies their aspirations, concerns, and the strategic intent behind the application. This qualitative input helps us design an app that aligns with the company’s objectives.

Define Goals & Objectives

We identify key technical performance indicators and business-centric metrics such as user acquisition, conversion, and revenue potential. We use these indicators to decide on goals and objectives for the software.

Scope Definition

This is about setting clear boundaries: What features are essential for the MVP (Minimum Viable Product)? Which ones can be scheduled for later phases? Defining the scope ensures that the project remains focused and feasible.

Competitive Benchmarking

We analyze the market to identify direct and indirect competitors, assessing their strengths, vulnerabilities, and unique selling points to gain insights that position the application uniquely in the market landscape.

Key Deliverables

Evidence of our new knowledge and a clear path forward for the next phase.

Step 2

User Experience Design

As the core of user-centric design, this phase dives into the end-user's perspective, weaving a seamless journey that marries utility with delight.


We aim to craft an intuitive and engaging user experience (UX), merging client aspirations with actual user needs. It's not just about building an app but also about ensuring users value, enjoy, and advocate for it.


User Research & Personas

We uncover real user needs and pain points through focused surveys, in-depth interviews, and user tests. Through collaborative sessions, we work to build hypothetical user profiles. These personas, rich in detail, ensure the app is designed with real-world users in mind.

Information Architecture

Think of this as the blueprint of a building. A logical, structured content framework ensures users don't get lost in the digital maze and that all data has a location in the app to be displayed.

User Flows

We build User Flows to demonstrate the steps users will take to achieve specific goals. User Flows become especially important when dealing with complex conditional workflows. It allows clients, designers, and developers to share a mutual understanding of how features will work and what feature outcomes will be.


Wireframing allows us to create the general layout of the screen without deciding on the exact text and imagery to be used in the final designs. It's useful for:

  • Rapid Prototyping
  • Understanding Functionality
  • Demonstrating the User Flow
  • Ensuring a Solid Underlying Structure

Usability Testing

Here we take our prototype on a test drive with real users, seeking feedback and insights. By conducting this early on with low-fidelity prototypes, we are able to rapidly iterate on the proposed solution.


Digital inclusivity is our mantra. We ensure the design speaks to everyone, including those with disabilities. Our team follows WCAG AA guidelines (as a baseline), and the designs are set up to reflect them.

Key Deliverables

Detailed documentation about the users and plans for how they will interact with the app.

Step 3

Technical Discovery

At this stage, design meets technology. We ensure that our app's blueprint aligns with a robust, scalable, and agile technology stack.


We will conduct a thorough assessment of your product requirements, UX designs, and UI designs to balance priorities and gauge the scope of development. This involves reviewing your needs and selecting the best-fit technology stack for seamless integration and future scalability.


Tech Stack Research and Recommendations

The front-end and back-end languages, databases, frameworks, libraries, and other critical tools used to build an app are collectively known as the application’s “tech stack.” Choosing the appropriate tools and the right combination of tools directly correlates to an app's performance, scalability, maintainability, and budget. 

Our team will review your design and plans to determine the tech stack that best fits your project. This review includes determining what components will work best and leveraging past project experience and best practices to determine which resources, languages, and libraries will create an optimal ecosystem.

Architecture Ideation

Software architecture refers to the overall structure of a software system and the design decisions made to achieve desired qualities such as performance, scalability, and maintainability. It defines a software system's components, modules, interfaces, and data and outlines how they interact.

In this stage, our team will develop a rough understanding of how your redesigned application will function technically. They will work closely with you to analyze user stories and capture your project needs. 

Building a strong architecture is crucial to ensuring a robust and scalable foundation that supports the design and prepares the app for future iterations.

Key Deliverables

Assurance that what we are designing is technically feasible.

Step 4

User Interface Design

We move from the skeletal frame of UX to the artistry of User Interface (UI). Here, we breathe life into the wireframes, suffusing them with color, typography, and graphics, ensuring that the digital interface doesn’t just function but captivates.


Breathe life into our wireframes, transforming them into vibrant, interactive visuals that captivate users. Through a meticulous design process, we ensure the application's aesthetics not only delight but also amplify its functionality and user experience.


Style Concepts

Style concepts demonstrate different options for the look and feel of your application, including colors, fonts, etc. We generally create two or three style concepts for you to choose from, each with its own unique look and feel. Prior to creating the concepts we review your competitors products and determine how we'll differentiate your product from theirs. We combine these findings with your existing brand guidelines to create the style concepts.

Hi-Fi Mockups

High Fidelity Mockups serve as a visual representation of how the app will look. It incorporates the structure of the Wireframes with the visuals of the Style Guide. The mockups also incorporate visual assets like photography, illustrations, and icons. These serve as an accurate depiction of how the app will look when it launches.

Design System

Construct a cohesive, scalable set of design principles and components. This process ensures consistency across the interactions and visuals of the product. It also increases the velocity of the development efforts.

Responsive Design

Pulling everything together, we craft designs that fluidly adapt to varying screen dimensions. Our designers will build out high-fidelity mockups at each target breakpoint and provide guidance to the developers to do between them.

Step 5


Prototyping is our virtual sandbox. We simulate user journeys, validate our design hypotheses, and iterate. By enabling stakeholders and users to interact with a virtual version of the product, we refine, reassess, and revitalize our designs based on tangible feedback.


Craft dynamic prototypes to communicate the app's flow and functionality visually, giving stakeholders a tangible experience of the end product. This phase aids in refining design choices and ensures alignment between user needs, business goals, and technical constraints. Prototypes are one key way product design helps developers work efficiently.


User Journey Prototypes

Create visual paths that showcase how users will navigate and interact within the app. This prototype will demonstrate how the user achieves their goal and may also explore edge cases.

Navigation Design

Develop a coherent and seamless flow, ensuring users find what they're looking for efficiently. In the prototype, users are able to navigate to all views of the app.

Interaction Design

Incorporate subtle animations and cues that enhance user engagement and provide feedback. These micro interactions create a seamless feeling to the app and build a sense of delight.

Error Handling

Demonstrate system responses, ensuring that users are guided gracefully through any hiccups.

A/B Testing

Compare design variations to pinpoint which version fosters better user engagement and conversion.

UAT Testing

Ensure the design meets requirements and offers a glitch-free experience in real-world conditions.

Stakeholder Acceptance

Collaboratively align the design with stakeholder expectations and business goals.

Step 6

Development Prep & Support

As the design crystallizes, we pave the way for its technical realization. This phase involves meticulously documenting our design, elucidating nuances, and ensuring the transition from design to development is seamless, devoid of misinterpretations or oversights.


Bridge the design and development phases seamlessly, ensuring every design detail is documented—paving the way for developers to translate the design into a functioning app without hitches.
