By ensuring customers pay back their acquisition cost quickly, you eliminate cash as a growth bottleneck. This self-sufficiency means you aren't forced to take loans or investment prematurely, allowing you to negotiate from a position of strength and on your own terms if and when you decide to raise capital.
Breaking even on customer acquisition costs within 30 days is insufficient. The real goal is to generate at least double your CAC in gross profit. This surplus cash allows each new customer to finance the acquisition of two more, creating a self-sustaining and rapid growth engine without external capital.
