Former RingCentral COO David Sipes is to lead 8x8 as CEO, taking over from Vik Verma who has retired.
Sipes led RingCentral's go-to-market, product and engineering and is credited with being instrumental in its 12 year growth trajectory from a $10m revenue business to over $1bn.

"We believe Dave, with his operational expertise, strong industry background and go-to-market leadership is the right leader at the right time to fully realise our potential.”
Sipes added: “The cloud and work-from-home are transforming business communications for every employee and customer touchpoint, and have become a critical focal point for building competitive advantage for businesses today.
"8x8 has the opportunity to be central to the transformation of work.”
