The Flywheel Model differs from the Traditional Model in one fundamental regard. The enterprise sales team is exclusively inbound. They are explicitly denied the option of seeking business outside the customer base, and must gin up business from only existing customers. The enterprise sales team is an up-sell and cross-sell team. In fact, so is the mid-market sales team. Only the SMB marketing team is permitted to acquire new leads. In short, the Flywheel flips the traditional idea of enterprise people as hunters and others as farmers.
