Williams (pictured) was most recently senior vice-president of Edelman Intelligence in San Francisco – specialising in measurement strategy and data integration. He has more than 15 years’ experience working with businesses including Nike, Pop Sugar, Facebook, Salesforce and IGN.  

Darren Kemp, founding partner of Fiftyfive5, said: “This part of our business continues to grow in double digits – and we now run more than 50 monitoring programmes for clients in Australia and the region. We see significant opportunity to continue this momentum.”

Williams has moved from the US to Australia to take up this role. He said: “I feel very fortunate to join the team at Fiftyfive5, heading up the performance and tracking team, a meaty and challenging role that builds upon my recent measurement and strategy experience.”
