I think stock dilution, is a big concern. With each round of funding, and the more stock they issue, this makes your stock worse less unless they can guarantee it. Im not an expert ( please someone expand), but my simple understanding , is something like lets say you get options to buy 10 stock out of 100 total shares, thats a lot. But then next round of funding they issue more stock and now you still have the option to buy 10, but there are 1000 outstanding now. What you had before is worth a lot less.
