GazeHawk

GazeHawk was a webcam-based eye-tracking startup founded in December 2009 by Brian Krausz and Joe Gershenson, offering affordable eye-tracking usability and ad-testing services that ran on ordinary consumer webcams instead of expensive dedicated hardware. Backed by Y Combinator (S10) and 500 Startups, the company was acqui-hired by Facebook in March 2012 — Facebook hired the engineering team but explicitly did not acquire the product or technology, and the founders moved on to unrelated backend and product engineering. GazeHawk operated no public API, developer portal, or SDKs; the domain today serves only a legacy static marketing and blog site for the defunct product.

GazeHawk is profiled on the APIs.io network. Tagged areas include Company, Eye Tracking, Usability, Advertising, and Analytics.

GazeHawk’s developer surface includes engineering blog and 2 more developer resources.
