THE PARTNERSHIP

Why Koast × Flex

Media buyers front the cash for ad spend and wait weeks for revenue to land. The gap between the two is the ceiling on how fast an account can scale.

Flex closes that gap with Net 60 terms at 0% interest, and pays 2.3% back on the spend itself. Koast users get the strongest version of the package, plus $500 on acceptance, because Koast and Flex are working on the same problem from opposite ends: Koast makes the spend work harder, Flex makes it cheaper to carry.
