The problem is the "proper valuation" though, isn't it?
Especially for something like CloudFlare. I'm a customer, I understand their product and what they're offering, I like their products, I think it works pretty well, I see them having a lots of sites on their CDN, I think they're providing value.
I don't have the faintest idea what their suites of products are worth to the average website owner, and how many of those average users they have, or how much it would be worth to large enterprises etc. And even if I did, I wouldn't have any idea of what that should translate to in share prices.
So in the end all I can reasonably do is very basic stuff like looking at revenue vs share price, and maybe at how competitors are valued. Are you going to have any success with that kind of analysis that's barely scratching the surface?
