As of March 2009, "Gizmo5 serves more than six million consumer and business users" after six years. Skype adds that every 17 days. I don’t know if Gizmo5 has been successful enough to create attractive cash flow. If Skype owned the business, could Skype quickly build profits?

Gizmo5’s IP prime asset could be its SIP gateway. They’ve built on top of it a SIP-to-Skype (OpenSky) gateway, support for Google Talk, and Gizmo Voice, a Gizmo5/Google Voice mashup. If the code is good enough, it might be the base of an enterprise server product or a hosted service.
