rhonda shantzPorter Novelli alum Rhonda Shantz has left Symantec to lead marketing for Silicon Valley adtech company Rocket Fuel.

Redwood City-based RF, which went public with a splashy IPO in September, was founded by Yahoo veterans and uses big data and artificial intelligence to place ads online.

Shantz exits a nearly seven-year stint at Symantec, where she was VP of global marketing for the company and its Norton cybersecurity brand.

She was previously a partner and global technology industry lead for Porter Novelli during a decade with the firm in the Bay Area, and earlier global PR manager for Hewlett Packard.

RF reported first quarter revenue of $74.4M with a net loss of $11.2M. It raised about $116M in its fall IPO and expects to top $420M in revenue this year.
