Every company is different, startups included. In my first full-time job, I was at a big company and completed my first project in a couple months. As it turns out, that was actually my project for the year. I literally had nothing to do (it was a gov't funded project, so my hours were paid for the year, regardless). Startups need everything done all the time, so there's a much higher probability of being pulled into non-coding tasks. That said, it sounds like your boss & company don't really seem to care what you're looking for in terms of growth and experience. Again, this isn't uncommon at any company. You may have just landed in a role that's not a great fit for you.
