You should go in with the assumption that the company will fail. So if you're looking to relocate to a new city consider what will happen in that case, i.e. are there other employers in that city who you'd want to work for, etc.

It also depends on the stage of the investment, the later stage an investment the safer it's likely to be. If it's a seed investment of 500k then it's going to be a high-risk startup, if it's a Series B of $20m then it's likely to be a safer bet.

A better question to ask in terms of growth plans is what sort of metrics does their VC need them to hit in the next 12 months for them to be willing to make a follow-on investment.
