This card’s application process differs from that of a typical business credit card. Instead of requiring a personal guarantee, Brex requires the applicant to link a corporate bank account to their card to act as a security deposit.\r \r \r This can be advantageous to the applicant as card activity does not affect your personal credit and you can be approved instantly instead of having to file paperwork and wait for a response from the issuer. In order to qualify, you will need to supply an EIN and link a bank account of least $50,000 if that money is professionally invested, and a minimum of $100,000 if not.
