<p>Circle co-founder Sean Neville will be leaving his post as co-CEO of the firm at the end of this month, according to a report from <a href="https://www.coindesk.com/circle-co-founder-sean-neville-steps-down-as-co-ceo?utm_source=twitter&amp;utm_medium=coindesk&amp;utm_term=&amp;utm_content=&amp;utm_campaign=Organic%20">CoinDesk</a>. In a company email, Neville said he felt it an "appropriate" time for the transition in leadership, but did not disclose a specific reason for his exit.</p> <p>He will remain on Circle's board as an independent director and continue working with the company's joint venture with Coinbase, <a href="https://www.theblockcrypto.com/linked/2180/coinbase-launches-usdc-stablecoin">CENTRE</a>, which issues stablecoin USDC. </p> <p>Neville co-founded Circle with Jeremy Allaire in 2014 as a payments firm before obtaining a Bitlicense from the New York Department of Financial Services. It was the first to receive such a regulatory nod. </p> <p>Neville did point to Circle's sale of subsidiary exchange Poloniex as a moment of transition, per CoinDesk. Circle acquired Poloniex in 2018 for around $400 million before <a href="https://www.theblockcrypto.com/post/43794/circle-spinning-out-poloniex-plans-to-invest-100m-and-not-serve-us-clients">selling it</a> a year later. </p>
