In the early days of Google Photos, we observed that while many users dropped off quickly, a stable percentage remained engaged, which gave us confidence in the product's potential for growth.

Once we received approval, our team from Bump collaborated with Google engineers to build Google Photos from scratch in about nine months, launching it in 2015.

To create a product like Google Photos that billions will use, you must be fully committed and understand that success rarely follows a straight path; expect failures and challenges along the way.

After selling our company to Google, we planned to rebuild our photo roll idea with Google technology to create Google Photos, and I was optimistic about its success.

The core idea of Google Photos was to create a home for all of your life's memories, making photos and videos easily accessible and organized through AI technology.

Google Photos demonstrates how understanding the content of images can lead to successful product features, serving as a valuable lesson for startup founders.

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.
