It's also a huge win if you need multiple people to sign a document.

Without a tool like HelloSign you need to email the document to each person one by one to get everyone to sign on the same "paper". It's a mess and takes up a lot of time and coordination.

With HelloSign (and other similar tools), you can just send out an email with a link to everyone at once. They can sign the document asynchronously in whichever order they want, and when everyone has done that, you get a notification.
