Thank you for the link to the memo. I'm looking at joining a startup after a decade in enterprise and am doing my research. Where would one find the details to the questions in the financing section (burn rate, money in bank, valuation in next financing)? I was able to pick info on funding rounds from crunchbase, # of employees from Co. site but that's the most I've got. Any pointers will be helpful.
If you want to do the math your self, for most companies the cost is predominantly determined by salaries. If you can figure out the number and positions of employees, you should be able to estimate it fairly accurate.
Figuring out how much they make on the top line is slightly harder, but you can usually estimate it if you can find out how many users they have (which is often not very secret) and if you can guess at how much they make per user (usually roughly the same figure across an industry - so again, not overly secret)
If you make your calculations up front, you will know which variables you are least confident about and can try to pry about them at an interview.
