It derisks the company at low cost because you're raising money on great terms. It's almost always a good idea to have extra cash in the bank, especially when that cash comes.

I once heard a quote along the lines of "the company that wins the space is the last one to raise funding before the funding market turns south."

Because you're running payroll. You could lose it all pretty quickly if you screw a few things up.

for one, you don't know how the environment and access to capital might change. So it might make sense to take some cash whilst it's available.

Best time to raise money is when you don't need it.
