SCA has today announced a new leadership structure and several promotions for LiSTNR, marking a pivotal step in the platform’s evolution as Australia’s leading locally owned digital audio destination that has become a market favourite for advertisers – underpinned by powerful first-party data capabilities.
SCA has ambitiously invested in LiSTNR since its launch in 2021. Today, the LiSTNR app has 2.25 million signed-up users, with the LiSTNR Audience Network — which includes radio in-stream and podcasting — attracting more than 10 million monthly listeners. The latest Australian Podcast Ranker also features more LiSTNR podcasts than any other platform*. With strong year-on-year revenue growth, LiSTNR is uniquely positioned for commercial success.
Recognising LiSTNR’s critical role within SCA’s All About Audio ecosystem and its expanding commercial potential, SCA has appointed Chief Operating Officer Stephen Haddad to lead the platform into its next phase of growth, alongside promotions for Grant Tothill, Sam Cavanagh, and Mike Williams.
This new leadership structure aligns deep audio and content expertise with core operational priorities. By placing proven talent in these strategically significant roles, SCA is sharpening its focus, accelerating audience growth, and unlocking the full commercial and creative potential of the LiSTNR platform.
Haddad said: “LiSTNR’s success comes from years of strategic investment in building Australia’s strongest digital audio network, powered by robust first-party data, world-class content, and a clear vision for the future. I’m excited to lead this new chapter with a strengthened leadership team. Grant, Sam and Mike each bring a wealth of expertise and drive, and will play a key role as we sharpen our focus on audience growth, content excellence, and commercial impact. With this team in place, backed by talented content and commercial teams, and ongoing innovation in adtech, we’re well positioned to extend LiSTNR’s leadership in the digital audio space and deliver even greater value to audiences and advertisers.”
