Keyhole, Inc, founded in 2001, is a pioneering software development company specializing in geospatial data visualization applications.
Initially launched as a spin-off of Intrinsic Graphics, first round funding came from a Sony venture capital fund and others, additional capital came from an NVIDIA bundling deal, from the CIA (via its venture-capital appendage, In-Q-Tel) and from angel investor Brian McClendon (who later came on as a board member and VP).
Keyhole's marquee application suite, Earth Viewer, emerged as the highly successful Google Earth application in 2005; other aspects of core technology survive in Google Maps, Google Mobile and the Keyhole Markup Language.
