Charmaine Griffith joins Think HQ to head up growth

Think HQ is accelerating its Sydney expansion, appointing Clemenger BBDO growth lead Charmaine Griffith as head of growth in a newly created role.

Griffith spent the past two and a half years as growth director at Clemenger BBDO. Before that she held senior growth roles at VML across Australia and New Zealand, and brings broader integrated agency experience from PwC’s CMO Advisory, OMD and Initiative.

In her new role, Griffith will lead Think HQ’s NSW growth strategy and strengthen the Melbourne-headquartered agency’s presence beyond Victoria. The hire follows recent wins with Cancer Council Australia, Stride Mental Health and Raising Children Network.

She will work alongside Sydney director Sarah Wood, driving coordinated growth across Think HQ’s integrated capabilities in strategy, creative, PR, tech and diverse audience engagement.

Think HQ founder and managing director Jen Sharpe said Griffith brings clarity and ambition to the agency’s national plans.

“Charmaine’s appointment reflects the strength of our ambition in NSW and nationally," Sharpe said. "From the first conversation, it was clear she truly understands our unique strengths in the market and brings a proven ability to lead growth in complex, integrated environments."

Wood said Griffith’s influence is already evident. “Charmaine’s one of those people who instantly lifts a room. She’s smart, curious and genuinely invested in helping clients and teams grow. I’m so excited to have her on board at Think HQ Sydney as we build on our growth trajectory and keep driving positive change,” she said.

Griffith said she was drawn to the agency’s mission and integrated model. “Think HQ has built something rare – an agency that solves complex problems for major clients, while staying true to their values. That’s good growth, and exactly what I want to scale in NSW and nationally,” she said.

Griffith has started in the role at Think HQ’s Sydney office.
