Networking App - Business School Idea

I am a current MBA student and I am looking for some feedback on a business idea.

Pain: It is very difficult for active networkers to manage their professional connections.

Solution: An app that pulls in your LinkedIn contacts and let’s your organize them based on importance.

Key Features (for each contact):

• A “Notes” section where you can actively compile key information about a contact. You can refer back to you notes and continually update your notes as your relationship progresses.

• A “Reminder” section that allows you to set up reminders to reach out to a contact within a certain period of time.

• A “Schedule Meeting” section where you can send calendar invites directly to your contacts.

• A “Chat” function where you can ask questions and send information (like a resume or news article).

I would really appreciate it if you could provide some advice on my idea.

Also, would you be willing to pay for this app (if done well)?

Thank you!
