Square finance chief leaves to become Nextdoor CEO

Sarah Friar, longtime CFO for payments company Square, is leaving the company to become CEO of neighborhood social network Nextdoor, Square said on Wednesday. A search is underway for her successor.

Why it matters: Friar has been credited with helping build Square into a successful public company, often running the day-to-day when CEO Jack Dorsey is busy across the street being CEO of Twitter. Shares are down more than 8% in aftermarket trading on the news.
