App that mails greeting cards in your handwriting

'Signed,' is an app that allows you to handwrite a message on a greeting card from your phone and have that card delivered by mail. With thousands of greeting card companies with crazy names in the market, the only way to stand out is to go primal. Like smart doorbell company Ring, the strategy was to go as primal as possible, while not straying into generic territory that would prevent the name from being granted a trademark.
