For decades, the Sobratos have leveraged land and capital to help fill the needs of a large share of Silicon Valley’s nonprofit sector through capital grants, the donation of land or buildings directly to nonprofits, or the proceeds from the sales of Sobrato-owned buildings.


By the close of 2018, the Sobrato family had donated over $258M in land donations and capital to nonprofits—enabling building projects for 93 organizations in 26 Silicon Valley cities. (Additionally, the sales of several TSO buildings—generating $571.5M through the end of 2018—help fund the work of Sobrato Philanthropies.)
