Opus strategic business director Freddie Guilmard said the agency had spoken to the logistics company and presented to its marketing team as part of TNT's ongoing agency review before THA Group collapsed. It has since worked on a number of projects for TNT.
Meanwhile, former THA Group key account director Phil Whetter has joined Opus as executive producer and Zara Gregory, who was a senior project director, becomes head of events.
Whetter worked for THA Group for 14 years and said that he brought a technology company, which he declined to name, with him from THA. "A big client came with me to Opus and I have managed to keep the whole team from THA Group working together on its events on a freelance basis," he said.
Whetter said he took on the post at Opus because it is a "nimble agency with creative spark".
"It reminds me of the old THA Group," he added.
Opus is launching a client tool, Pulse, this month, which is designed to track and analyse employee engagement and key performance indicators. "Pulse will enable Opus to deliver more powerful and brand engaging programmes," said Guilmard.
