VideoSurf

VideoSurf, established in 2006, operated as a video discovery platform engineered to enhance how users find and engage with online video content. The company was founded by Lior Delgo, Achi Brandt, Eitan Sharon, and Shai Deljo. Lior Delgo, who served as CEO, was a serial entrepreneur, having previously co-founded the travel search engine FareChase, which was acquired by Yahoo in 2004. This background in building and exiting search-related technology ventures provided a solid foundation for VideoSurf's strategic direction.

The core of VideoSurf's offering was a computer vision technology that analyzed content within video files, frame by frame. Unlike conventional video search engines that relied on text-based metadata and tags, VideoSurf's system could visually identify people and specific moments inside the videos themselves. This approach allowed for more relevant and precise search results, enabling users to pinpoint the exact content they were looking for across a multitude of video-hosting sites like YouTube, Hulu, and Dailymotion. The platform indexed billions of visual moments, offering a fundamentally different and more granular search experience.

The company's business model focused on providing this advanced search capability directly to consumers through its website and also likely through partnerships with content providers who could leverage the technology to increase discoverability. By 2011, the platform claimed to attract 20 million unique monthly visitors. VideoSurf secured a total of $28 million in funding from investors, including notable figures such as Al Gore and Sheryl Sandberg, as well as venture capital firms like Pitango Venture Capital and Verizon Ventures. In November 2011, Microsoft acquired VideoSurf for a reported $70 million. The primary objective of the acquisition was to integrate VideoSurf's visual search technology into the Xbox 360 and Xbox LIVE ecosystem, aiming to improve content discovery and power voice search features for the entertainment platform.
