We have been running a SaaS product for SMBs for about 4 years now. If you bootstrapping and running on very low revenue like we do, the only option is to keep your costs even lower. We usually have enough money in the bank to pay salaries for next month and a half. The longer we stay in the game, the better our product gets. The better our product gets, the more traction we get via word-of-mouth. Not exactly what PG would call "growth", but enough to keep us in the game. (Our adwords spending is around $500 a month.) The other way, I have heard that works is hiring sales people. But for that you need to raise at least some amount. And price your product a bit higher too.
