Ask HN: How do venture-backed startups handle their money?

Curious to know from personal anecdotes/stats how VC-backed, early-stage start-ups think about their money (ranging from $ received from investments, revenue, expenses).

In particular, I imagine that the way seed-funded companies handle money is different than how a Series A company thinks about and handles their money. I also imagine there to be differences depending on the nature of the company, e.g., whether or not the company is making revenue, is hardware vs. software, etc.

Are there patterns about how start-ups think about their money, especially across stages and types of company?
