It takes quite some time to see how thing goes, and usually they are masked by PR, or simply the quality of work might not be what you expecting, i would its definitely better to invest in company that have a big bank to keep going, rather than tiny startup that give you a hardship time which most of the people wouldn't be enduring. You could actually weight the process by reading their commits and stuff, not just solely on news if you want to have a greater picture.
