A Product Campaign That Pulls at the Heartstrings

Ring's Search Party campaign is an awesome example of product-led marketing. They take their existing product and apply it to a brand new use case that anyone can take advantage of, for free. You lose your pet, and the Ring app will help you find it using all of the existing Ring cameras in your neighborhood. Right away, you have thousands of potential Ring customers downloading the app to create a profile for their pet. I love how Ring executed this one.
