The six partners of Andreessen Horowitz pledge half of their lifetime income to charity. As part of the announcement, the partners donate $1 million to six Silicon Valley nonprofits. Horowitz says:
The idea behind it is to lead by example. It’s a show of appreciation for everyone in Silicon Valley.
The move is highly influenced by Andreessen’s wife, Laura Arillaga-Andreessen who had publishes a philanthropy book, Giving 2.0, the year before.
