reigniting growth was focused on improving retention, i.e. fixing our “leaky bucket” problem
how to segment and model our users by engagement level
The chance a user comes back this week if they resurrected (from a longer absence) last week
put together a new product team focused on acquiring new users, called the Acquisition Team
new users increased by only 3%
A free ride is a constant incentive
better at basing our decisions on data, insights, and foundational principles
The chance a user comes back this week if they reactivated last week
With this data, we could create a forward-looking model and then perform a sensitivity analysis to predict which levers would have the biggest impact on DAU growth
CURR’s impact on DAU was 6 times its impact on MAU
leaderboard was the Retention Team’s first breakthrough!
came from a cautionary tale from Groupon’s CEO
whether there was a strong correlation between retention and usage of particular Duolingo features
“I have a 1,435-day streak!” and added, “with no streak freezes!”
our success with the streak mechanic further showed us that we could squeeze major wins from existing features.
several of these bets worked, including expanding internationally
the share of our DAU with a streak of 7 days or longer increased almost 3 times to more than half of our DAU
