Three-dimensional search engine Physna wants to be the Google of the physical world In June of 1999, Sequoia Capital and Kleiner Perkins invested $25 million into an early-stage company developing a new search engine called Google, paving the way for a revolution in how knowledge online was organized and shared. Now, Sequoia Capital is placing another bet on a different kind of search engine, one for physical objects in three dimensions, just as the introduction of three-dimensional sensing technologies on consumer phones are poised to create a revolution in spatial computing. At least, that’s the bet that Sequoia Capital’s Shaun Maguire is making on the Columbus, Ohio-based startup* Physna.
