The Golden State Opportunity Foundation is a left-of-center non-profit founded by investor and activist Joe Sanberg. The Foundation’s main program is CalEITC4ME, which engages in outreach to low-to-moderate-income Californians in order to enroll them in California’s state-level Earned Income Tax Credit program.
The Golden State Opportunity Foundation was founded in 2015 by investor and left-of-center activist Joe Sanberg.  Prior to founding the Foundation, Sanberg was a prominent advocate for legislation instituting a state-level Earned Income Tax Credit (EITC) program, a welfare program wherein participating low-to-moderate-income individuals and couples receive a refundable tax credit the size of which varies according to recipients’ income and number of children. In 2015, when California instituted an EITC program, Sanberg considered the amount of investment the state put into outreach to low-income communities inadequate and created CalEITC4ME, the foundation’s flagship program, to facilitate awareness and advocate for the expansion of the new program. 
CalEITC4ME is the Golden State Opportunity Foundation’s main program. It seeks to increase enrollment in California’s Earned Income Tax Credit program and the federal EITC program. In order to accomplish these goals, the program, engages in direct outreach through publicity events, fliers, and texts. Additionally, CalEITC4ME features versions of its website in Spanish, Mandarin, Vietnamese, Korean, Tagalog, and Russian, and offers free tax preparation services to California residents.
CalEITC4ME also leads advocacy campaigns for the expansion of California’s EITC program. In January 2019, California Governor Gavin Newsom (D) approved a state budget that doubled the size of California’s EITC program, for which CalEITC4ME claimed credit. 
Founder Joe Sanberg is an investor and left-of center activist. Before becoming involved in activism, Sanberg worked for financial services firms including Blackstone and Tiger Global Management. Sanberg’s wealth largely derives from a successful early investment in Blue Apron, the food delivery service, and Aspiration, a financial services company of which he is a co-founder. Aside from his involvement with the Golden State Opportunity Foundation, Sanberg sits on the advisory boards of the University of California Riverside’s School of Public Policy and Casa Teresa, a nonprofit based in Orange County, California, which provides services to pregnant women experiencing homelessness, domestic abuse, and drug addiction.
