Biggs will be signing on with local mobile and digital activation firm Gravitas as chief strategy officer at the start of October.
In a phone interview, Biggs said that he was parting ways with FH on good terms and has helped the PR agency appoint his replacement.
Because of a request from the replacement's current employer, Biggs was unable to disclose the individual's name. However he was able to share that the individual is currently employed with a TV operator.
"When i joined FH to build its digital capabilities, I appreciated the chance to work with a multi-national PR network," Biggs said. "I gave myself three years, and those three years have come to a close. It's time to move on."
Biggs chose to join Gravitas because he missed his "entrepreneurial roots" and appreciated the 9-year-old digital agency's nimbleness. "It is my opinion that large agencies are not able to incorporate new technologies and use them for marketing communications fast enough," Biggs said.
"Gravitas wants to expand and to open up to big multinational clients," he said. "I'm tasked with helping to take it to the next level."
Prior to FH, Biggs helmed digital agencies Palava Digital and Digital Cortex. He was also co-founder and 'chief guru' of Web Guru Asia.
