8x8, Inc.
A maker of cloud-based communications software for businesses, 8x8 provides phone systems, video conferencing, team messaging, and contact center tools that replace old-fashioned on-premise hardware. It was founded in 1987 as Integrated Information Technology, a semiconductor company, before rebranding as 8x8 in 1996. The quirky name comes from the 8x8 pixel blocks used in video compression algorithms, a nod to the company's early work on video technology.
