founders wants me to join for just equity, how much should I ask for?
anamax: > How much should I ask for?More than you can get.  (Unfortunately, biz folk respect folks who play games.)It comes down to alternatives, yours and theirs.You shouldn't join if you've got better alternatives.  They shouldn't pay you (salary, equity) more than it would cost them to get "good enough" from someone else.If they don't get you to sign on, what are their alternatives?
