PG makes the comparison explicit later in the essay:
"There are many analogies between fundraising and dating, and this is one of the strongest. No one wants you if you seem desperate. And the best way not to seem desperate is not to be desperate. That's one reason we urge startups during YC to keep expenses low and to try to make it to ramen profitability before Demo Day. Though it sounds slightly paradoxical, if you want to raise money, the best thing you can do is get yourself to the point where you don't need to."
