There is a big difference between raising during a Seed stage (<$2m) where you are principally selling vision, market need, and why you/your team are ready to crack it. Often, at this stage, you are pre-product-launch so there are few business metrics to share.
When you're going for a Series A or later, then you will still principally be selling your vision, but there will be a lot more scrutiny of your actual business metrics and economics. Again, which metrics will depend on what type of business you are. I found this TC article to be pretty accurate to my own experience...hopefully you find it usefull.
