If you measure the size of a startup by time to public beta, then you are making a fundamental mistake. The thing is, before you go public, you can spend as much or as little time as you want, but once you are public and people actually star using your stuff, you will have to continuously iterate and refine your stuff. So I would say the majority of the work comes AFTER you go public, and hence time to public beta should not be your criteria for determining the size. Having said that, it is always better to do stuff one thing at a time. It ensures that a. you don't get swamped, and b. your full attention goes towards the one thing you're working on.
