BVNK, a crypto startup specializing in stablecoin infrastructure, has successfully raised $50 million in a Series B funding round led by Haun Ventures. This round, which also saw participation from Coinbase Ventures and others, values the company at $750 million, according to sources. This follows a $40 million Series A round in May 2022, which valued BVNK at $340 million. The new capital will support BVNK's expansion in the U.S., with new offices in San Francisco and plans for New York City. Co-founder Jesse Hemson Struthers views stablecoins as a critical upgrade for payment systems.
