CEO: Rob Bearden
Founded one year ago, Sunnyvale, Calif.-based Hortonworks debuted release 1.0 of its Hortonworks Data Platform in June. Built on Hadoop and other open-source software from the Apache Software Foundation, the Hortonworks Data Platform adds other tools and technologies that make it easy for businesses to implement a big data system and develop applications for managing and analyzing all that information.
Hortonworks is a spin-off of Yahoo's Hadoop engineering team. The company is widely seen as the chief competitor to the more established Cloudera, which offers its own Hadoop distribution. The company's name comes from the Dr. Seuss book "Horton Hears a Who," in keeping with the Hadoop elephant theme.
