D3 bolsters leadership team with senior hires across data, digital and client services
Independent media agency D3 has appointed Torsten Stolt, Alex Duval and Courtney Barnett to senior leadership roles as it enters its next growth phase.
D3 has strengthened its leadership team with three senior hires, Torsten Stolt as Head of Data & Technology, Alex Duval as Head of SEO & Experience, and Courtney Barnett as Client Partner, marking the agency’s next stage of growth across Australia and New Zealand.
Stolt brings nearly two decades of experience in data strategy, analytics and AI-driven solutions, including five years as Business Intelligence Director at Together. He will lead D3’s data and technology division, focusing on building privacy-safe data foundations and helping brands unlock commercial advantage from first-party data.
Duval joins with more than ten years’ expertise in SEO, CRO and content strategy across independent agencies including Sprocket and Krunch.co. He will oversee D3’s digital content and experience design offering, integrating AI solutions to maximise the value of clients’ organic search and website performance.
Barnett brings both international and local agency experience, having held senior roles at IPG Mediabrands in London and as Group Business Director at GroupM New Zealand, leading accounts such as Uber and Mars. At D3, she will focus on ensuring the agency’s capabilities translate into measurable business outcomes for clients.
The trio join General Manager Lani Jamieson, who stepped into the role earlier this year, alongside co-founders Richard Thompson and Alex Radford. Together, they form an expanded leadership group guiding the agency through continued growth as the industry evolves amid AI, data and connected digital transformation.
Stolt said: “Data has always been central to effective marketing, but the industry is now at a tipping point. Brands need solid data foundations to compete in a world shaped by AI and shifting privacy rules. I’m excited to help D3’s clients move from talking about transformation to making it real — building systems and strategies that create lasting commercial advantage.”
Jamieson added: “Our clients want clarity and confidence as the industry shifts. With leaders like Torsten, Alex and Courtney on board, we’re bringing together the right expertise to guide them through that change. It’s a huge momentum boost for the agency and a reflection of the ambition we share with our clients.”
