Building companies
Hooked
How products build habits through the Hook Model.
Key concepts
- Hook Model: trigger, action, variable reward, investment
- External triggers give way to internal triggers (emotions)
- Make the action easy
- Variable rewards keep users coming back
- User investment loads the next trigger
How I use it
I haven’t built a product around the hook model. I value the book for the opposite reason: it explains how the products I use every day are designed to hold my attention.
Once you understand triggers, variable rewards and investment, you see them everywhere: in social feeds, in LinkedIn, in apps and recommendation engines. Knowing how the loop works helps me navigate it, and it has genuinely helped my mental health.
