When I was an early-stage founder, I bristled at the idea of making a five- or even three-year financial projection of my business. I can promise you one thing: It will be dramatically wrong. But as part of your fundraising, you need to make them anyway, and there are a couple of great reasons for that.
VCs understand as well as you do that you can’t predict the future. Hell, that isn’t just true for companies at the pre-seed stage; if founders could predict the future, there wouldn’t be so much nervousness around IPOs.
