ContextWeb (Now PulsePoint)

ContextWeb was a digital media technology company founded in 2000 in New York, specializing in online advertising and contextual targeting technology. The company provided analytics, ad-serving solutions, and operated a contextual ad exchange with real-time bidding (RTB) capabilities. ContextWeb received backing from notable venture capital firms including Draper Fisher Jurvetson (DFJ) and DFJ Gotham Ventures.

In 2012, ContextWeb merged with Datran Media to form PulsePoint, which later pivoted to focus on healthcare marketing technology. PulsePoint was subsequently acquired by Internet Brands, the parent company of WebMD and Medscape. Today, PulsePoint operates as a healthcare marketing platform helping marketers reach health consumers through data-driven activation and analytics.
