Andy Bechtolsheim, David Cheriton, and Ken Duda founded the company in 2004, and the technical bet was software: EOS, a network operating system built on unmodified Linux with a published state database, running on merchant silicon rather than custom ASICs. That combination won datacenter switching share from Cisco, particularly at cloud titans and financial exchanges where latency and automation matter. Customer concentration is high, with hyperscalers supplying a large share of revenue. Jayshree Ullal led the company from 2008 through its 2014 listing and beyond, from Santa Clara.
