THE PARTNERSHIP

Why Koast × Slash

Media buyers move more money through cards than almost any other kind of business, and most banks treat that volume as a risk instead of a relationship.

Slash was built for operators who spend: unlimited virtual cards, granular controls, $35bn a year in payments, and cashback on all of it. Koast chose Slash as its official banking partner because the two products serve the same desk. Koast users get the preferred version of the package.
