Christine Sandler, Coinbase’s US Head of Sales, has joined Fidelity Digital Assets (FDA) as its Head of Sales and Marketing to direct efforts to expand FDA into new markets, and serve a broader set of institutional clients.

FDA made the announcement in a press release on April 10. It is an institutional provider of custody and trade execution services for digital assets, and is a Fidelity Investments Company. Fidelity Investments boasts more than $7.3 trillion in client assets under administration.

Before Coinbase, Sandler was Head of Equity Electronic Sales for the Americas at Barclays Investment Bank, and Executive Vice President and Global Head of Sales for NYSE Euronext. She was also Head of Electronic Sales at investing and wealth management firm Merrill Lynch, and worked as a buy-side trader.

Separately, Coinbase recently lost another executive. Its Vice President of International Business Dan Romero announced his leaving in a Medium post on April 12. He joined Coinbase in 2014 when the cryptocurrency exchange only had 20 staff – it now has over 700.

His reason for departing was not given, but he did say, “Staying true to a mission often requires doing hard (or even unpopular) things. But I’ve been lucky to learn first-hand that it’s those hard things that often generate the most value.”

During his time with the exchange, Romero said he had the chance to work across “almost every aspect” of the Coinbase business, including banking partnerships, and both consumer and institutional businesses.

In the last few months, Coinbase has witnessed other departures, including director of data science and risk Soups Ranjan, and senior compliance manager Vaishali Mehta.
