I wasn't joking too much... high growth is bad for a company's 'health', no matter what is driving that growth (VCs or just PMF). By health here, I mean people, processes and product. It helps, a lot, if the team has done high-growth before and understand what the compromises are and where the organizational and technical debt is and how to pay it off, but you're still going to go through hell. Again, this is a choice: are you going to leave demand on the table or not? VCs are probably not going to let you say 'yes' to that, but can/will you anyway?

On a personal level, stress is going to be bad for you as well. But both high growth and low growth (below profitability that is) will give you stress, so if you don't want that health impact, look for a salary, not for equity...
