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.
