"Hū" is an app for entrepeneurs which helps them visualize the potential interest of their product or idea (to understand Who may be interested, or even narrow down Who their target market is).
When an entrepeneur has an idea, their friends and family may be supportive and encouraging of an idea which will be a waste of time and money. It can be difficult for the average American to access basic market insight to determine whether an idea could have financial success. Part of the process in securing funding from an investor is the ability to present data that shows your idea has an active target group and a potential for success.
