How to find hidden growth opportunities in your product | Albert Cheng (Duolingo, Grammarly, Chess.com)

Albert Cheng has led growth at three of the world’s most successful consumer subscription companies: Duolingo, Grammarly, and Chess.com. A former Google product manager (and serious pianist!), Albert developed a unique approach to finding and scaling growth opportunities through rapid experimentation and deep user psychology. His teams run 1,000 experiments a year, discovering counterintuitive insights that have driven tens of millions in revenue.

What you’ll learn:

1. How to use the explore-exploit framework to find new growth opportunities

2. How showing premium features to free users doubled Grammarly’s upgrades to paid plans

3. What good retention looks like for a consumer subscription app

4. Why resurrected users drive 80% of mature product growth

5. Why “reverse trials” work better than time-based trials

6. The three pillars of successful gamification: core loop, metagame, and profile
