Fintech firm Mercury has successfully raised $200 million in a funding round led by TCV, with participation from Sequoia Capital, Andreessen Horowitz, and Coatue Management. The company, which offers banking services to startups, serves over 300,000 customers and reports an annualized revenue of $650 million. The recent boom in AI startups has driven increased demand for Mercury's services. Additionally, Mercury has received conditional approval from the U.S. Office of the Comptroller of the Currency to apply for a federal bank charter. This move aims to enhance its lending capabilities, integrate with payment networks like Zelle, and reduce dependency on partner banks. Mercury's founders emphasize their commitment to pursuing an independent IPO in the future.
