A few core concepts could probably use a little more clarity; - Real "Virality" is very different from "Word of Mouth", and implies that users bring others users to the product in the process of using it, to some greater or lesser degree. Photosharing apps are a good example. Uber to a lesser extent - I first learned about the service when my friend ordered a black car. Zynga's games were notorious for trying to manufacture virality by rewarding facebook friend-invites with more coins/gold/whatever. - Inbound and outbound sales are very different beasts. The former is the result of SEO, PR, word-of-mouth, content marketing etc. Trying to "scale inbound sales" won't get you far. If you have a working outbound sales process, on the other hand, you can often ramp it up several-fold. - "Channel partnerships" can be extremely useful, especially when selling to SMBs. A recommendation for some accounting software from your bank manager is very persuasive.
