Sounds like you are looking to leave one job to get another job. Take some time to think about why joining an as of yet unknown "startup" would be better than the job you currently have. If you don't know where you would be going, then it might just be filling in imaginary holes. One of the biggest things that's different between a big corp job and a startup might be that you are "closer to the metal" of the business part. What you do has a much larger effect on the ability for the business to succeed or fail when you are part of a small development team. Perhaps you could go even further and build your own business. This might prepare you better and give you an idea of what it is about a startup that you really would give up your current job for. Perhaps your new business would even do well enough to provide the income when you quit your day job.
