Hello Santa`, an app that offers live video calls with Santa Claus, has given thousands of kids around the world a chance to chat with Jolly Old Saint Nick. The four-month-old startup behind the app, `Make Believe Lab`, created it after a three-year-old boy asked his father if he could FaceTime with Santa. The team conducted market research using Amazon Mechanical Turk and found that parents were looking for a realistic and authentic-looking Santa experience. With the help of Zapier, they automated their customer support by running queries on new lines in their SQL database and triggering actions in Zendesk and Mandrill. They also experimented with different features, such as offering recorded videos for purchase after calls. The app has become an instant sensation, earning its first press coverage within two weeks of launch and receiving positive reviews from parents and kids alike.
