Independent media agency Media33 has announced the appointment of former Spark Foundry Managing Director Pete Butler as Managing Partner, commencing 1st March, 2026.

Butler joins Media33 following a senior leadership career spanning some of Australia’s largest media agencies, where he has led teams, driven growth, and partnered closely with major brands across multiple categories. In his new role, he will work alongside Media33’s executive leadership team in Jenna Lambert, Mick Bradley and Michael Lambert to support the agency’s next phase of growth, strengthen client partnerships, and further develop the agency’s strategic and operational capabilities.
