Circle to Leverage Leahy’s Insight and Knowledge
Prior to that, Leahy was CEO of Visual Trading Systems, a provider of platforms and business intelligence analytics for the foreign exchange and over-the-counter (OTC) derivatives industry. Moreover, he served as the Chief Operating Officer (COO) of FXPrimus, a role he held for over a year, following a transition from oneZero Financial Systems where he was the Head of Business Development for Americas.
Leahy’s career, which dates back to 2002, encompasses other senior roles including as Managing Member of Capital Markets Access Partners, LLC and Back Bay FX Services, LLC, according to information made public on his Linkedin profile.
Leahy’s experience across the mainstream markets should help Circle at a time when the firm is expanding the reach of the offering that is primarily focused on retail trading and investing to appeal for B2B partnerships.
Currently, the crypto unicorn puts greater emphasis on its USD Coin (USDC), a stablecoin pegged to the US dollar. Furthermore, Circle will open the doors of its stablecoin to businesses with a dedicated account that provides a toolbox of APIs to allow developers to build on top of USDC.
