On the relative value of startup stock

How do you compare the potential value of different stage companies? And as a company progresses what is the appropriate amount of stock to give new employees?

Using data from Crunchbase and Yahoo Finance we can calculate the average value created per company broken down by how much money they have raised. From this we can then compute relative returns at the different stages, e.g. $1M raised, $10M, $100M, etc.

tl;dr

For this exercise we'll calibrate relative to expected return from a company that's raised $1M.

just write something funny, dufus.

The token system is ridiculous because it makes security weaker, by offering a
larger surface area for attack.

If I had to guess, Salesforce is concerned that users are embedding their
passwords into scripts which could be stolen and used outside the company for
other purposes. Why are users putting their passwords in scripts? I imagine
it's because of the web-centric oauth flow coupled with short oauth token
expiration intervals but THATS a different story.

So *within* an authorized set of IP addresses, the regular password works.
