Akamai says chief executive will leave
Akamai Technologies Inc., which helps businesses deliver data at faster speeds over the Internet, said CEO Paul Sagan will leave by the end of 2013. The Cambridge company is starting a search to replace Sagan, who became president in 1999 and CEO in 2005. Akamai’s sales more than quadrupled during his tenure. Sagan helped Akamai become less dependent on its content-delivery network business. He acquired firms to add services and products that would differentiate Akamai, analysts said.
