One Problem, One Person
Goetz does not invest in platforms. He invests in solutions.
WhatsApp: cheap messaging for people in countries with expensive SMS.
Zoom: reliable video for people who were tired of bad conference calls.
Specificity Wins
The narrower your target, the better your product.
Build for one person. Make it perfect for them. Then expand.
Products built for everyone delight nobody.
Solve a specific problem for a specific person.
Then Expand
WhatsApp started with international messaging. Now it is the world's most used app.
Zoom started with business calls. Now it is everywhere.
Both started specific. Both became universal. In that order.
