I know quite a few developers who have a knack for following market trends and jumping on the rocket ship before it is about to launch.

It's actually not that hard if you think about what filter you would apply. The one hard part is finding recruiters who specialize in placing people at these companies, and, of course, passing the interview (or at least enough success that the interviewer doesn't tell the recruiter you are a poor quality candidate).
