i think most entrepreneurs in SV do not think of regulations when starting a company. for example, there aren't any tax laws to my knowledge that makes me go, "ah gotta take care of that before i can code."
of course, there will be an impact if a company wants to IPO, but that comes much later on. However, even in that case, it's more about revenue/income generation.
i'm interested in seeing what's going to be the liquidation route for startups now since the M&A market is quiet now.
