The story
Founded by Andi Gutmans and Zeev Suraski in 1999.1
Zend Technologies was founded by Andi Gutmans and Zeev Suraski who, along with other Israeli graduates of the Technion, the Israel Institute of technology, further developed PHP after its initial creation by Rasmus Lerdorf. The name Zend is a combination of Suraski's and Gutmans' forenames, Zeev and Andi.
In 1997, Gutmans and Suraski rewrote the parser of PHP-FI, originally written by Lerdorf, resulting in PHP 3. In 1998 they redesigned that parser completely and named it the Zend Engine. PHP 4 is based on the first version of the Zend Engine.
In 1999, their company Zend Technologies was formally established and received initial funding from the Israeli venture capital funds Platinum Neurone Ventures and Walden Israel. Business executive Doron Gerstel was recruited to head the company as CEO.
In August 2006 Zend raised $20 million in a Series D funding.
In February 2009, Zend's co-founder Andi Gutmans was appointed as CEO, after serving as the company's VP of research and development. Zend also recruited Mark Burton, who had served as EVP of worldwide sales at MySQL, as executive chairman.
In October 2015, Louisville, Colorado-based software developer Rogue Wave Software acquired Zend.
Shortly after being acquired, co-founder Andi Gutmans left the company in February 2016.
In January 2019, Rogue Wave Software was acquired by Minneapolis, Minnesota-based application software developer Perforce. In April, Perforce's Zend Framework was spun off as a separate project to the Linux Foundation, and was renamed Laminas.
