DoubleClick was an interactive marketing and advertising technology company founded in 1996 by Kevin O'Connor and Dwight Merriman. It pioneered ad serving, targeting, and campaign measurement for publishers and advertisers, went public on NASDAQ as DCLK, and was acquired by Google in 2008 for roughly $3.1 billion. Its products were folded into Google's advertising stack — DoubleClick for Publishers became Google Ad Manager and DoubleClick Digital Marketing became the Google Marketing Platform. DoubleClick no longer exists as an independent company or API provider; doubleclick.com now redirects to Google Marketing Platform. This API Evangelist profile is retained as a historical venture-portfolio record (surfaced via lightspeed-venture-partners) rather than a live, enrichable developer surface.
