Lightbox was a photo-sharing platform that allowed users to connect and share their experiences on social media platforms like Facebook and Twitter. The company primarily served individual users who were interested in sharing their photos and moments with a broader audience. Operating in the social media and digital photography market, Lightbox provided a user-friendly interface for uploading and sharing photos. The business model was likely based on user engagement and potential advertising revenue, although specific financial details were not disclosed. The company made money through user interactions and possibly through partnerships or advertising. However, Lightbox.com was discontinued on June 15, and the team has since joined Facebook to work on new projects for mobile users. The company did not sell its user data to Facebook and plans to open-source portions of its code on Github.
