Second, your analysis doesn't work without including zeroes. Pretend all the failures raised a lot of money. Your line would point down.
Your analysis was marginal and you're not taking the feedback very well.
You are right that the line would point down if all failures raised a lot of money at the seed/Series A stage, but that's not the case. This intuitively makes sense as only a small select group of companies/founders can raise large initial rounds (serial entrepreneur, amazing traction, etc) and most will raise smaller sums.
But thx for comment. Update with zeros coming soon.
