By default, the Sharetribe platform displays profile names using the entire first name and the first character of the last name. It doesn't provide the option to use one name, because it requires both fields to be filled in.
If you have a brand or business name you want to use, there is an easy way to display it instead. Just fill in the first name field with a parallel bar ("|") (or other symbol if you prefer) followed by your business name, then type a parallel bar alone into the last name field. For example, if you put in first name: " | Hostess Haven" and last name: "|" - the end result will display as | Hostess Haven |.
