I set up a donor advised fund (DAF) with the Silicon Valley Community Foundation when I sold my company in 2000. At that time they had the policy of selling all the donated shares immediately. It turned out to be one of the best things I did. Now I have more time available to look into how to give money in meaningful effective ways and I have a pot of money available for this thru the DAF where I don't have to be doing the math on whether or not I can 'afford' the donation. My post acquisition world has been much richer for the interactions I've had with people I respect that stemmed from this.
