In other words, it pays to be the pretty girl in the room. The fact that the underlying product, business, and people did not change highlights how most venture deal flow is filtered by relying on relativistic gauges of peer interest. It's pretty sad, honestly. Of course, not all are like this, for example YC and other programs with formalized processes.
We did change by committing to B2B, but insofar as we didn't change the foundational product, team, or market, you are correct. Which is why I call it a hack -- doing what it takes rather than what you think is important.
I wouldn't call it a hack so much as learning to sell to your market. Just like showing you that Tide will take the stains out of your clothes better than the next detergent, or that Bud beer will help you attract women, whatever. In this case your market is VC's and your product is your company, you finally started pushing their buttons.
