Various roadblocks disrupt host and participant user flows, resulting in poor conversion.

Painpoints for host

Repeated Invitation
Hosts have to manually send group chat invitation to different participant for coordination and communication purpose.
Painpoints for participants

Key Challenge

Which is the best solution?

My take: WeChat Mini Program

Billow is a small pre-seed startup with limited resources and tight project deadlines. As a product designer under this pressure, my primary responsibility is to select a platform that maximizes user experience while ensuring timely product delivery.

Option 1

Host on Website

Option 2

Build Mobile App

Option 3

WeChat Mini App

Option 4

Hire add-hoc admins

Strategy

Piggybacking WeChat Ecosystem to
optimize event registration flow

Automatic Info Fetching

Mini-App can pre-fill forms, personalize content, and streamline account-related actions without requiring repetitive data entry. This functionality not only reduces the risk of human error but also saves users valuable time, preventing the frustration that can arise from typing in redundant information.

Create, Share, Participate
within one app

Users can interact with the Mini-App directly within WeChat, which allows for real-time messaging, notifications, and updates in a single interface. This integration reduces friction and ensures that users remain engaged without the distraction of external links or third-party logins.

Design Process

Design Through Iterations, Make It Sharp

Information Architecture

A well-structured information hierarchy, along with both low-fidelity and high-fidelity prototypes, to guide the design process.

Mid-fi -> High-fi -> Testing

Based on the user flow and info architecture, I sketched the low-fi prototype for concept validation and tested the user flow with 7 stakeholders.

Branding

Built branding with
a systematic, replicable method.

Create Mood board

My team and I hosted a workshop where we collaboratively created a moodboard to capture the essence of the Billow app. This final moodboard became the foundation for Billow's branding style.

Vote for Branding

Once we are satisfied with the mood board, I went up creating three main color palette and let the team member as well as 5 community members to vote the one that they like the most.

Curate Color Palette

After we chose our primary color, I curated it using a color palette tool to ensure consistency, rather than relying on visual estimates.

Final Color Palette

With that, we developed the final color system. The guideline below details all 90 shades and their corresponding accessible text color values. I also included accessible text colors on a white background for reference.

LEARning & Reflection

Scrum is efficient.

Scrum's iterative approach allows teams to adjust priorities and project goals as new information or changes arise, ensuring that the product evolves based on feedback and market needs.
Be Mentally Prepared
for Changes.
New WeChat Oversea Usage Policy restricted usage for gathering purpose, which sabotaged our app. But our team quickly switched to another online platform, Wix, and continue the service while building branding for broader marketing purpose
