Zend seeks a sustainable open-source model

Open-source software company Zend Technologies, hoping to double its revenue this year, says it will narrow its focus to big business and Web 2.0-style start-ups, according to incoming CEO Harold Goldberg.

Venture-backed Zend makes development tools for running Web applications written with PHP, an open-source scripting language.

As the company seeks to grow beyond is current size--with annual revenue between $10 million and $30 million--Goldberg said he intends to focus the company on a handful of growth initiatives, down from eight or nine now.
