"I think the pitfall you are alluding to is hitting ramen profitability and then spending all day fire fighting rather than creating new features."
I don't think that's what he's alluding to at all. He's talking about business success, not how you spend your time. There are plenty of people who create products for small markets and can't make the growth jump past that early small market into a larger one. This isn't always (or even OFTEN) a feature-creation problem.
Here's some cool math: If your acquisition is linear ("we sign up 3 paying customers every day") and your churn is percentage ("we lose 8% of our paying customers every month") you will eventually hit a point where your growth STOPS (unless you can fix one of those two stats). The zombie state Drew is talking about (I think) it where your revenue is largely not growing, you can feed yourself but no one is ever going to buy you, and you've run out of "move-the-needle" features/efforts that can improve acquisition or retention. "Walking Dead" is what investors call it.
