The first funding for Google as a company was secured in August 1998, in the form of a $100,000 contribution from Andy Bechtolsheim, co-founder of Sun Microsystems, given to a corporation which did not yet exist.
On June 7, 1999 a round of funding of $25 million was announced, with the major investors being rival venture capital firms Kleiner Perkins Caufield & Byers and Sequoia Capital.
The Google IPO took place on 19 August 2004. 19,605,052 shares were offered at a price of $85 per share. Of that, 14,142,135 (another mathematical reference as √2 ≈ 1.4142135) were floated by Google, and the remaining 5,462,917 were offered by existing stockholders. The sale of $1.67 billion gave Google a market capitalization of more than $23 billion. The vast majority of the 271 million shares remained under the control of Google. Many Google employees became instant paper millionaires. Yahoo!, a competitor of Google, also benefited from the IPO because it owned 8.4 million shares of Google as of 9 August 2004, ten days before the IPO.
The stock performance of Google after its first IPO launch has gone well, with shares hitting $700 for the first time on 31 October 2007, due to strong sales and earnings in the advertising market, as well as the release of new features such as the desktop search function and its iGoogle personalized home page. The surge in stock price is fueled primarily by individual investors, as opposed to large institutional investors and mutual funds.
The company is listed on the NASDAQ stock exchange under the ticker symbol GOOG and under the London Stock Exchange under the ticker symbol GGEA.
