Despite not being able to launch our photo roll product, we recognized its potential, and several companies showed interest in it, indicating it could be the photo app of the future.

When we co-founded Instagram, we realized that the core of our product was about taking photos and sharing experiences, which led us to strip away distractions and focus on what truly worked.

We realized that the existing photos app on the iPhone wasn't very good, and if we designed it, we could make it much better.

After initially exploring various projects, we realized we should have focused on the captions app, which was already successful without any updates.

Paul Graham encouraged us to think bigger and suggested we replace the entire photos app on the phone to increase usage of our photo sharing product.

I co-founded a social app called Sober, aimed at helping people socialize after drinking, but it failed shortly after Snapchat launched, which had a similar concept.

When we launched our game 'Fates Forever' in 2014, it was a competitive multiplayer game on iPad, but it didn't succeed for various reasons, leading us to pivot.

We expanded Dropbox's focus beyond just file storage to include private photo sharing and team collaboration, acknowledging that files were evolving in their importance.

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