TL;DR: I designed and helped build FanFever, the world's leading CPOP (Chinese pop) fan platform, from the ground up. Within its first year it reached 5M+ registered users, 80% retention, and $10M in annual gross merchandise value — the result of designing community, fandom psychology, and commerce as one connected experience rather than three separate features.

The challenge

The CPOP fandom was massive, passionate, and almost entirely underserved by Western-built platforms. The brief was to design and develop a global fan platform from scratch that could capture that energy and convert it into a sustainable business — capturing 60% of the international CPOP digital engagement market.

Designing for fandom psychology

Fans don't want features; they want status, belonging, and proximity to the artists they love. So the core UX was built around identity and participation: collectible interactions, visible community rank, and moments that made fans feel close to their idols. Engagement wasn't a vanity metric here — it was the engine that drove 80% retention.

Connecting community to commerce

Most platforms bolt a store onto a social app. FanFever was designed so that merchandise was a natural extension of fandom, not an interruption of it. By placing commerce inside the emotional high points of the experience, the platform reached $10M in annual gross merchandise value in year one without aggressive marketing.

The results

• 5M+ registered users in the first year
• 80% retention
• $10M annual gross merchandise value
• 60% of the international CPOP digital engagement market

The takeaway for founders

The lesson that transfers to any consumer product: design the emotional core first, and let monetization grow out of it. When the experience genuinely serves the user's identity, revenue follows — it doesn't have to be forced.
