I guess I'm like Captain Kirk as the actor William Shatner. I don't think the answers are a clear either A or B. I would want to do the impossible: why not both?
The question would be what ways can a business model out acquisition and revenue generation in a way that can be proven to the leadership as well as to investors? It doesn't need to be something that hits a homerun. Simply a logical plan where both can happen and a logical contingency to address with that plan goes awry. I think ultimately, acquisition and revenue hold each other's hand and becomes a challenge when they are considered together.
