At least in my personal experience of doing this, you're often many years of living on savings and are in a bunch of debt and being able to get some cash from a funding event really helps with relieving the stress of barely making ends meet. Investors expect you to stay hungry for as long as possible, so even your salary is complete garbage, and the funding secondary is an absolute life saver that lets you sleep a little bit better at night after many years of dipping into the piggy bank.
