Retention: the hook model
The brutal reality: growth without retention is debt
If your retention is bad, every dollar you spend on marketing is just a donation to Facebook or Google.
The Conflict: Growth hackers focus on the “Top of the Funnel” (Ads).
But the real growth happens in the middle.
The Truth: Habit is the ultimate moat.
If your product doesn't become a biological requirement, it's just a commodity.
The Fix: Build a “Hook” that captures the user's brain before they have a chance to leave.
1. the trigger-action-reward loop
Habits are built in 4 steps:
1. Trigger: A cue (e.g., a notification or a feeling of boredom).
2. Action: The simplest behavior done in anticipation of a reward.
3. Variable Reward: The brain loves a slot machine.
If the reward is unpredictable (like a social feed), we stay hooked.
4. Investment: The more data/effort a user puts in, the harder it is to leave.
2. friction is the enemy
Your user has the attention span of a goldfish.
If they don't see value in the first 30 seconds, they are gone forever.
Onboarding is not about “teaching features”; it's about accelerating them toward the “Aha!” moment.
Smart words
RETENTION
The “Stickiness.” The ability of a product to keep its customers coming back for more.
VARIABLE REWARDS
The “Slot Machine.” Rewards delivered on a variable schedule to maximize dopamine and addiction.
AHA!
MOMENT
The “Lightbulb.” The specific point where the product’s value becomes undeniably clear to the user.
Tactical directives
1. Friction Audit: Count how many clicks it takes to see the first value.
Cut that number by 50% today.
2. Variable Reward: Add one element of “Unpredictable Value” to your product's daily use.
3. The Investment: Force the user to perform one small “work” (like setting a preference) in the first 2 minutes.
