Hiring is hard. When you're a startup - with no track record, scant funds, and less than top-of-line resources and benefits - it's usually a nightmare.
Thus, many startups never make it out of the "solopreneur" stage, a one-person show. There's nothing wrong with that, of course. But if you've got billion-dollar valuation dreams, or heck, even if you just want the slightest chance of an exit at some point, well, I probably won't be the first to tell you that you can't do it alone.
