Bravo! I occasionally mentor at startup events and I can't tell you how crazy it makes me when first-time entrepreneurs look down on getting revenue as some sort of grubby detail not quite worth their attention. I love it when people go after actual customer money; it forces them to pay careful attention to the heart of the business.
There is a risk, though. (I'm sure you know it already, but I mention it just to balance out my enthusiasm for others.) If a company's revenue is $0, investors can imagine anything they want. But if revenue is $1.39, investors may be subject to an anchoring bias [1]. I don't think that's a huge risk for companies that have a well-understood business model; if you are selling annual software subscriptions, it's pretty easy for investors to imagine scaling that up. But I think Twitter and Facebook were smart to avoid revenue for a long time because it let them sell the dream.
