Hi, I'm Waisun Joe 👋

📍 UK ↔️ Hong Kong | SaaS Founder | Growth + Data Analyst

I build products, then obsess over distribution: activation, retention, and measurable growth.

What I’m Doing

• Shipping product features (fast, small iterations)
• Running growth experiments (landing pages, pricing, messaging, channels)
• Measuring everything (funnels, cohorts, retention, attribution)
• Turning messy usage + revenue data into decisions
