Totally viable. As a micro ISV you have practically no expenses so the only things you need are a mediocre product and handful of customers and you're already sustainable. Once you get to that point tons of options will present themselves. Just build something that you know people need (meaning: there are other products in that space) that has a small enough scope so a single person can build it in a month or two. Then charge money for it. The software market is ludicrously large, and because you don't have marginal costs in a software business you can afford to make a lot of mistakes on the business side of things and still make a profit. You don't need a great product (plenty of lousy products sell well) and you don't need great business sense (many CEOs don't know what they're doing) and you don't need great marketing (same). For your business to work you have to clear the minimum bar in all three areas, but luckily the bar is set pretty low!
