Twitter Chief Operating Officer Adam Bain is leaving the company, according to a document the company filed with the Securities and Exchange Commission earlier this week. The news comes just weeks after Twitter’s attempt to find a buyer failed. Bain ran the company’s entire revenue business. Chief Financial Officer Anthony Noto will step into his vacated spot, meaning the company will need to find a new financial chief. Noto will continue to lead Twitter’s live content business, according to the SEC filing.
