The tools offered to businesses are only suitable for companies with finance and treasury teams of 20. Loop exists to change that. We''''re building the banking infrastructure for businesses that operate globally by default: multicurrency accounts, seamless international payments, modern systems to manage company financesthe things that should have existed years ago.
