It's one of the many different ways to start a company. Assuming you are not selling a physical product and don't actually require an office, and also assuming you are (or know) a developer that can work for free... Sure, that's exactly the right way to do it in my opinion.
Actually, that's exactly the method that me and my friendly developer are using for our own product, which should launch sometime this year. We both have a day job which would be hard to leave (we both have families to feed). And you're completely right that a single server is enough to host the MVP and we can expand further once we know we're on the right track.
