- Google : to organize the world’s information and make it universally accessible and useful - Facebook: to give people the power to share and make the world more open and connected. - Whatsapp: WhatsApp started as an alternative to SMS. Our product now supports sending and receiving a variety of media: text, photos, videos, documents, and location, as well as voice calls. Some of your most personal moments are shared with WhatsApp, which is why we built end-to-end encryption into our app. Behind every product, the decision is our desire to let people communicate anywhere in the world without barriers. - Signal: making private communication accessible and ubiquitous - Airbnb: To live in the world where one day you can feel like you’re home anywhere & not in a home, but truly home, where you belong.
