Coinbase President and COO Asiff Hirji announced his departure from Coinbase today, with Emilie Choi, VP of Business and Data set to replace him.says CEO Brian Armstrong.But he's just the latest in a string of high level executives moving on, and that's raised some concerns.Other recent departures include Chief Technology Officer Balaji Srinivasan, institutional sales director Christine Sandler, and vice president and general manager Adam White.So, is something going wrong inside of Coinbase? I spoke with one of my contacts inside of the company, who insists Coinbase is thriving - in fact, they're doing so well, other companies want their leaders for themselves.as far as how Coinbase is performing, they addThese claims all seem to check out, leading me to believe Coinbase really is doing just fine - for now.Where this becomes risky is possibly being unable to replace talent leaving, with talent equally or better qualified. So far, they seem to have been able to - but keeping talent is always preferred over taking the risks that come with replacing someone.The faster the revolving door spins, the higher that risk goes - that's how companies have found themselves in a position where multiple departments lack proper leadership at once - the turn from 'hugely successful' to 'sinking ship' can happen in the blink of an eye.Coinbase may need to explore increasing incentives for high-level employees to stick around.-------
