I thought I'd save everyone the trouble of going to a blog by ranting here directly.
A while back I was interviewing at a small company that really needed another developer or three. They wanted to hire and made an offer -- a 20k pay cut, but they were going to give me equity -- the magic word! Except the president/founder of the company wanted to keep 99%+ of the equity for himself, so anyone else let in on the deal had to share a fraction of the remaining 1%. I calculated that if the company was successful to the tune of $10 million, my share would still be worth less than my initial pay cut. I pointed this out to the senior developer who was trying to convince me to join, but his blind loyalty to the company seemed to preclude arithmetic.
Prior to that I worked at another smallish company where the president/owner kept around 95% of the stock. A few top people got 1% or less. Other companies say they want to hire "top talent", but they pay "market rates" -- which usually means the average according to some salary survey, or less, and no equity.
It seems like some founders are so attached to ownership that they can't part with it, even if it means greater success for themselves! It's like they have visions of dollars from owning the entire company instead of a vision of what's needed to get there. While a fraction of a percent of Google is worth a lot now, in order to get to that point, the founders had to part with the majority of the equity.
Some start-ups work with two founders, but some have half a dozen (like Excite) or more. Even reddit got more "founders" after the fact. If it turns out you need a new band member, are you prepared to redo the original founders' percentages, or do you have other plans?
