Research

Understanding the seller landscape.

To ground the work in real needs, we interviewed sellers across a range of business sizes and maturity levels. From this research, we developed a set of seller thinking styles that helped the team align on who we were designing for and where the greatest opportunities existed.

Strategy & Vision

Establishing a new north star.

Through a collaborative strategy workshop and rapid concept exploration, we aligned on a future vision focused on helping small businesses grow and scale. This phase established the core interaction model and a bold, high-contrast visual language designed to bring clarity to an otherwise dense and complex platform.

Systemization

Designing for scale.

To ensure the work could live beyond the project, we created a branch of eBay’s design system to support the new visual direction. We also documented components, patterns, and principles in detail, giving product teams a clear foundation to extend the design vision.
