Square 1 Bank

Founded in 2005 in Durham, North Carolina, Square 1 Bank established itself as a leading financial institution dedicated to serving the unique needs of the venture capital community and technology-focused, venture-backed companies at all stages of their growth. Its mission was to provide comprehensive banking services, including loans, treasury management, and depository accounts, tailored to the fast-paced entrepreneurial ecosystem. In 2015, Square 1 Bank was acquired by PacWest Bancorp and now operates as a specialized division within its subsidiary, Pacific Western Bank, continuing its focus on venture banking.
