Lark

Lark helps you to build and enrich professional relationships in your life. We are building a system designed to help you be more thoughtful with the people in your life. With Lark, you build a collection of the people you meet by connecting your email and calendar with social apps, including Twitter and LinkedIn.

Lark then populates each person’s entry with all the relevant information you would need to recall for any future meeting — ranging from their work history to latest tweets to the details on how you met and when you last communicated, among other things.
