Two Clearwire execs leave

Two Clearwire executives are leaving the company. Chief Strategy Officer Scott Richardson has resigned but it staying on as an adviser, while Chief Financial Officer David Sach said his is leaving to "pursue new opportunities." He will be replaced by Erik Prusch, who most recently served as CFO of Borland Software and is a former colleague of Clearwire CEO Bill Morrow.

The WiMAX operator appears to be bringing in more seasoned executives. While not replacing Richardson, Clearwire has tapped Teresa Elder, former CEO of Vodafone Ireland, as president of strategic partnerships and wholesale--an important piece of the company's business as it strives to meet its fourth-quarter goal of seeing its subscriber numbers exceeding all other 2009 quarters combined. Elder is also a former divisional president of AT&T Broadband. Morrow, who came to the company in March, is also a former Vodafone executive.  

While Clearwire added just 12,000 subscribers in the second quarter, Morrow said he was particularly upbeat about the wholesale side of the business as Comcast recently announced its intentions to be aggressive in rolling out WiMAX offerings and Sprint has the intention of selling WiMAX as part of its 3G/4G hybrid service offerings. Clearwire expects to offer mobile WiMAX service in markets covering 30 million people by the end of this year.
