What Is Craig Silverstein's Net Worth?

Craig Silverstein is an American computer scientist, technology executive, and philanthropist who has a net worth of $900 million. Craig Silverstein was the FIRST employee hired by Google. Technically, he was Google employee No. 3 after co-founders Larry Page and Sergey Brin, but he was the first person they hired after founding the company.

Craig met Page and Brin while all three were graduate students at Stanford University. His academic background in information retrieval, data mining, natural-language search, and large-scale data structures made him an ideal early collaborator on the search engine that became Google. After the company was formally created in 1998, Silverstein abandoned his doctoral studies and joined Google full-time.

Silverstein helped write portions of Google's original code, built infrastructure that supported the company's rapid growth, and played an important role in establishing Google's engineering culture. He remained with the company for approximately 13 years, eventually serving as director of technology before leaving in 2012 to join the nonprofit Khan Academy.

Silverstein also accumulated an enormous fortune from his early Google equity. While his original stock grant has never been publicly disclosed, a 2010 newspaper profile estimated his net worth at more than $800 million. His fortune could have grown into many billions of dollars had he retained all of his Google shares. Craig and his wife, Mary Obelnicki, have instead committed to giving away the majority of their wealth and created Echidna Giving, which plans to grant and fund $6 billion over several decades.

Early Life

Craig Silverstein was born in Guam and grew up primarily in Gainesville, Florida. His parents were physicians, and he later described growing up in a household where education was highly valued without being aggressively pushed on him.

Craig attended public school in Gainesville and earned a perfect 1600 on the SAT. His aptitude for mathematics and computers led him to Harvard University, where he studied computer science.

Harvard

At Harvard, Silverstein was elected to Phi Beta Kappa and received a Microsoft Technical Scholarship.

In 1993, he was part of the three-person Harvard team that won the Association for Computing Machinery's International Collegiate Programming Contest. The victory marked Harvard's first win in the competition, which brings together elite student programmers from universities around the world.

While still an undergraduate, Craig also worked on software projects for Microsoft. One project involved developing an interactive application based on the music of composer Igor Stravinsky. He later worked on a communications interface for a handheld computer.

Silverstein graduated from Harvard with honors in 1994 with a degree in computer science.

Stanford

After Harvard, Craig enrolled in Stanford University's Ph.D. program in computer science.

His research interests included information retrieval, data mining, clustering enormous datasets, natural-language search queries, and the construction of highly efficient data structures.

Those interests placed him directly in the path of two fellow Stanford graduate students who were attempting to build a better way to search the internet: Larry Page and Sergey Brin.

Craig and Sergey co-authored academic work while at Stanford. Silverstein also spent summers at Xerox PARC, where he worked on clustering algorithms for large datasets, and later worked at Verity in Sunnyvale, California, developing technology that allowed search engines to process natural-language queries.

When Craig learned about Page and Brin's experimental search project, he immediately recognized its potential. He began helping with the technology while the search engine was still a Stanford research project.

Google Employee No. 1

In 1998, Page and Brin formally created Google after raising early financing, including $100,000 investments from Stanford professor David Cheriton and Sun Microsystems co-founder Andy Bechtolsheim.

They hired Craig as Google's first employee.

Silverstein worked alongside the founders during Google's earliest days, including the period when the company operated from the Menlo Park garage of Susan Wojcicki, who later became Google employee No. 16 and CEO of YouTube.

Craig wrote parts of Google's original code and helped build the systems required to crawl, index, and search the rapidly expanding internet. He is also credited with helping create Google's exact-phrase search feature, which allows users to place quotation marks around a phrase to search specifically for those words in that order.

Silverstein expected Google to be a relatively short chapter in his career. He later recalled imagining that he might work there for several years before returning to Stanford, becoming a stay-at-home father, or pursuing another project.

Instead, he stayed for approximately 13 years.

As Google expanded from a Stanford project into one of the world's largest technology companies, Silverstein became director of technology. He remained through Google's 2004 IPO and continued working at the company until 2012.

Google Stock and Net Worth Analysis

Craig Silverstein's original Google stock grant has never been publicly disclosed, making it impossible to reconstruct his fortune with the precision available for founders Larry Page and Sergey Brin.

In October 2010, the Mercury News published a profile stating that Silverstein's net worth had been estimated at "somewhere north of $800 million." The article did not provide a share count or explain the source of the estimate.

Our current $900 million net worth estimate should therefore be understood as an estimate of Craig's remaining personal wealth, not necessarily the maximum value his Google shares generated over his lifetime.

The potential scale of that fortune can be illustrated with some intentionally simplified math.

Google shares traded at approximately $536 when the 2010 profile was published. If an $800 million fortune at that time had consisted entirely of Google stock, it would have represented roughly 1.49 million shares.

After Google's subsequent stock distributions and splits, an untouched position of that size would today be worth more than $20 billion.

There is no evidence that Craig actually owned exactly that many shares or that he held anything close to his entire position for another decade and a half. He almost certainly sold stock, paid taxes, diversified his investments, and transferred substantial assets to charity.

But the exercise demonstrates how enormous the wealth generated by his early Google equity may have been. Craig could have disposed of more than 95% of that hypothetical position and still retained roughly $1 billion worth of Alphabet shares.

Other early Google employees provide further context. Jeff Dean, who joined as employee No. 30 in 1999, accumulated a fortune we estimate at at least $500 million. Google's longtime legal executive David Drummond sold approximately $475 million worth of Google shares between 2009 and 2019 alone. Even Google chef Charlie Ayers received an early stock grant that, had it remained untouched, would eventually have grown to be worth hundreds of millions of dollars.

Silverstein was Google's first hired engineer and stayed for 13 years. It is therefore reasonable to conclude that the total fortune produced by his Google equity reached well into the billions before taxes, diversification, and philanthropy.

Khan Academy

In February 2012, Craig left Google to join Khan Academy, the nonprofit educational organization founded by Salman Khan.

Khan Academy provides free educational videos, exercises, and other learning tools to students around the world.

Silverstein served as dean of infrastructure and returned to hands-on engineering work. His decision to leave one of the world's most powerful technology companies for an education nonprofit reflected an interest in using technology to expand access to learning rather than maximizing his personal earnings.

Echidna Giving and Philanthropy

Craig and his wife, Mary Obelnicki, began supporting girls' education through what became the Echidna Giving Fund in the mid-2000s. Echidna Giving later developed into their primary philanthropic organization.

The name comes from the echidna, the unusual spiny Australian mammal sometimes called a spiny anteater. Craig reportedly became fond of the animal during a trip to Australia. The organization has also noted that "kid" appears in the middle of the word "Echidna," fitting its focus on education.

Echidna concentrates on improving educational opportunities for girls in lower-income countries. Its grants have supported teacher training, education research, advocacy, leadership development, and programs designed to keep girls in school.

Craig and Mary signed the Giving Pledge in 2014, committing to give away the majority of their wealth. They have also said they intend to distribute their fortune during their lifetimes rather than create a permanent family foundation or leave most of the money to their children.

Earlier descriptions of their philanthropic plans contemplated distributing between $500 million and $700 million over several decades.

Their ambitions have since increased dramatically.

Echidna Giving now describes itself as a private funder that intends to grant and fund $6 billion over 30 years.

That figure does not mean Echidna currently has $6 billion sitting in a bank or investment account. Unlike a traditional private foundation, Echidna operates through philanthropic sponsors and donor-advised structures that do not produce a standalone public tax return disclosing its total assets.

However, Echidna publicly identifies Silverstein and Obelnicki as its founders, and there is no public evidence of another outside benefactor providing the underlying fortune. The $6 billion commitment is therefore one of the strongest indications that Craig's Google equity generated wealth far beyond the amount he continues to hold personally.

Personal Life

Craig married longtime partner Mary Obelnicki after proposing to her at the Eiffel Tower in Paris in 2013. Mary has worked in technology and philanthropy and has been deeply involved in the couple's charitable activities.

Craig has also served on the board of trustees of the Exploratorium science museum in San Francisco.

In 2009, Craig and Mary donated $5 million to the Sebastian Ferrero Foundation, an organization created to improve pediatric healthcare in Gainesville, Florida.

Despite the enormous wealth generated by his Google career, Silverstein has maintained a notably understated public profile. A 2010 newspaper profile noted that the man then estimated to be worth more than $800 million was still driving a ten-year-old Nissan Maxima.
