Key Achievements
While PhD students at Stanford in 1995-1998, Brin and Larry Page built the BackRub web-crawling prototype and developed PageRank, a method that ranks a web page highly when many highly ranked pages link to it. The National Science Foundation describes Brin as a graduate student on Stanford's NSF-supported digital-library project who joined Page's work; the pair described the resulting Google prototype in the 1998 paper 'The Anatomy of a Large-Scale Hypertextual Web Search Engine'.
Brin and Page founded Google in September 1998. By Alphabet's own account in 2019, the company had grown to more than 100,000 employees, with products including Search, Maps, Ads, Gmail, Android, Chrome, Google Cloud and YouTube.
In the 2004 founders' letter in Google's registration statement, Page and Brin set out an auction-based public offering and a dual-class share structure in which Class B shares carry ten votes each, and the letter describes Brin as focusing on engineering and business deals alongside Page and the CEO Eric Schmidt. Google became part of the Alphabet holding company in 2015; Brin was Alphabet's President until 3 December 2019, when he and Page left their executive roles while remaining co-founders, shareholders and board members.
Moments That Reveal Them
At Google I/O in June 2012 Brin presented Project Glass by staging a live demonstration in which a skydiver wearing the glasses streamed a jump toward the Moscone Center, followed by stunt cyclists wearing them. He announced that only conference attendees could order the Explorer edition, which was not a consumer product.
Fronting a high-profile live demonstration of an unfinished product is consistent with risk tolerance; Brin and analysts later judged the publicity premature, so the same stance carried a cost. Risk Tolerance
At Google I/O in May 2025, asked what he had learned from Glass, Brin said he felt he had 'made a lot of mistakes with Google Glass', citing his lack of knowledge of consumer-electronics supply chains and the difficulty of a reasonable price. He added that the next launch should polish the product before a demo.
Publicly naming his own errors and the change he would make is consistent with belief updating; this is a single reported on-stage statement. Belief Updating
Turning Points
By 1998 Brin and Page were unsure they wanted to run a company, and Brin was reluctant to leave the Stanford programme. Battelle reports that Brin's adviser told him he could return to graduate school and finish his thesis if Google did not work out; Brin recalls answering, 'Yeah, OK, why not? I'll just give it a try.' Google was incorporated in September 1998.
Stepping out of a doctoral programme with a safety net, after weighing the choice, is consistent with proactive agency; the account rests on a journalist's interviews and Brin's own recollection. Proactive Agency

- Engineering and Technology History Wiki (IEEE), 'Milestones: PageRank and the Birth of Google, 1996-1998' -- independent institutional account of the PageRank algorithm and the three commemorative plaques. Read in full; its reference list also records the January 1998 Stanford technical report by Page, Brin, Motwani and Winograd and the patent filed in Page's name.
