We initially tried a revenue-sharing model with one customer, but it didn't work as they wanted to attribute revenue increases to other factors.

We started with a freemium model, but realized it distracted us; we shifted to a paid model and consistently increased prices over time, which helped us focus on serious customers.

Kevin and I are notoriously horrible at monetization; we launched Eventbrite with a basic service and a premium service, but we never put anything exclusive in the premium service, which confused our customers.

We initially started a company based on a bad idea, trying to create a wiki for stock research, but it never took off, which is common in consumer businesses where success can feel random.

After our initial launch, we didn't see immediate success and even explored creating a roommate matching website before pivoting back to Airbnb.

We realized we needed to charge businesses a few hundred dollars a month instead of just $20-$30 to make our business model viable.

We initially struggled to find a problem to solve because we were generally happy people without many issues, which made it challenging to identify a business idea.

Airbnb's photography service started from a personal experience where they realized better photos could enhance listings, leading to a successful on-demand photography network.
