Founded in 2001, Keyhole is a pioneering software development company that offers an interactive software enabling users to view 3D images of any place on earth and search for other information such as hotels, parks, automated teller machines or subways. Keyhole's marquee application suite, Earth Viewer, emerged as the highly successful Google Earth application in 2005, and other aspects of core technology survive in Google Maps, Google Mobile and the Keyhole Markup Language. Keyhole secured funding from a Sony venture capital fund, NVIDIA bundling deal, the CIA (via its venture-capital appendage, In-Q-Tel), and angel investor Brian McClendon, who later became a board member and VP.
