Credit Compound

Mercury

A startup-focused banking platform whose IO Mastercard adds 1.5% flat cash back on top of its checking, savings and treasury accounts. Qualification rests on your Mercury deposits rather than personal credit, with no personal guarantee. The card is an extension of the bank account, not a standalone product.

Application Rules

  • ▸You must bank with Mercury; most US businesses qualify for IO from their first day on the platform
  • ▸Holding $15,000 or more across Mercury accounts unlocks higher limits and flexible payment schedules
  • ▸Cash back pays out monthly and requires accounts in good standing
