OVERVIEW

VanTech Med is a Canadian startup using AI and robotics to improve the lives of seniors. Its core product, Sundae (formerly Sunny), is an AI-powered doll designed to alleviate social isolation and loneliness among the elderly.

Background

Problem

SundaeDoll’s existing website is undermining customer engagement and sales due to several key issues:

  • Struggling to balance technical functionality with commercial presentation

  • Lack of essential content and trust-building features

  • Cluttered design, difficult navigation, and poor usability

The redesign transformed the user experience, elevating design, streamlining navigation, refining content, and improving usability. We revamped key pages and launched new ones to deliver clearer product information, enhance usability, and build customer trust.

Solution

  • Launched a new website that boosted customer trust, raising the trust score from 2.3 to 4.2 out of 5, an 82% improvement.

  • The ease of navigation improved by 80%

  • Users achieved a 100% task completion rate for adding a product to the cart, increasing the ease-of-use rating from 1.8 to 4.8 out of 5

Impact

"This design team was amazing to work with. All members were very engaged, knowledgeable and handed in all deliverables on time. Each individual contributed meaningfully to the end project. They were able to actively listen to our team's requirements, issues and concerns and provide great work arounds and resolutions. I had a great experience with this team!”

- Vanessa L., CEO of VanTech Med

RESEARCH

Project Kickoff

Understanding the client’s business goals and her concerns with the existing website

Our kickoff meeting clarified the client’s business goals — increasing customer engagement, building trust, and driving conversions. We also gained insight into the stakeholder’s perspective and her concerns about the current website:

Heuristic Evaluation

After meeting with the stakeholder, we conducted a heuristic evaluation using Nielsen Norman’s 10 usability principles to identify design issues. I facilitated a workshop and created this presentation to visually highlight problems with the existing website. We used these findings to inform the redesign, prioritizing usability throughout the process.

User Interviews

Conducted the startup’s first user interviews for the website and identified 4 key areas for improvement

This was the startup’s first user research effort for the website, helping the stakeholder see the value of interviews in uncovering key challenges and guiding solutions. To understand why the current site was undermining engagement and sales, we interviewed 6 potential customers (family members of seniors), then collaborated on affinity mapping to identify 4 key areas for improvement:

1. Design
2. Content & organization
3. Shop page
4. Building trust and credibility

To address the issues identified by users, we analyzed 3 direct competitors to understand their approaches. These companies emphasized clean design, clear product information, and compelling customer testimonials.

Feature Prioritization

Finalizing must-have features to meet user and client needs

Considering the 4 key areas for improvement and the client’s needs, we collaborated with the stakeholder to confirm the must-have features for the new website and potential features for future improvements.

The old website confused users with a cluttered homepage that presented all information at once and included non-functional “Coming Soon” links in the navigation. I updated the sitemap made it easier for users to navigate and find information.

DESIGN

How did we tackle the 4 key improvement areas identified in our user research?

Design Solutions

Overview:

1. Design: a style guide to ensure consistency and enhance usability.
2. Content & Organization: improved content organization and navigation.
3. Shop page: clear product details, plans, and pricing in a streamlined layout.
4. Trust & credibility: new Meet Sundae, About Us, and Research pages.

1. Design

The redesign significantly diverges from the original. With only the logo, font, and two primary colors blue and yellow provided, we developed the style guide, expanded the color palette, and selected icons to reflect the brand’s professional yet friendly aesthetic. To address usability issues and ensure design consistency, I took the initiative to guide the design direction, and our team communicated and collaborated regularly to ensure design alignment.

2. Content & organization

I contributed to the homepage design and ensured consistency across different screens. The homepage showcases Sundae, featuring a clean, user-friendly design with streamlined navigation to help users easily access information. The layout highlights Sundae’s key features and product details, ensuring a seamless browsing experience.

3. Shop page

For the shop page, we enhanced the clarity of product details, plans, and pricing by organizing the information in an easily digestible format. Clear headings, bullet points, and a streamlined layout were implemented to enhance navigation on the shop page, making the Add to Cart process easy to follow.

We created new pages for Meet Sundae, About Us, and Research to enhance credibility and build trust with customers by providing clear, detailed information about Sundae’s features, technology, safe data collection, AI safety, doll therapy, and clinical articles, as well as the company’s team and mission.

4. Trust & credibility

TEST & ITERATE

We conducted usability testing with six participants to assess the design, uncover usability issues, and identify areas for improvement. The testing focused on the new navigation, user confidence after learning about the product, and the ease of adding a product to the cart.

Design system for developer handoff

For the project handoff, we held a meeting with the developers to ensure a smooth transition. I took the initiative to lead the organization of the design system, making sure it was clear, cohesive, and ready for seamless implementation. This design system provided the client with a comprehensive reference for future updates and design continuity.
