On December 17 Coinbase announced it had confidentially filed the paperwork to start its IPO process. The following report on his leadership style and company culture was originally published on October 25.

Business Insider spoke with 11 Coinbase insiders who had direct dealings with CEO and cofounder Brian Armstrong to determine what it's like to work at Coinbase and for him.

Sources described an intense executive. They also detail awkward social interactions and miscalculations on how his communications would be received.
