"I am excited that my role and this community program are new for Marketplacer," says Rinker. "The company has experienced rapid growth in recent years and it's critical that we find new ways to innovate and support our growing customer base.
"I'm also looking forward to leveraging my experience in launching and growing seller communities to build similar structures at Marketplacer, while democratising the process and curating the experience for our customers.
"Ultimately, my aim will be to create a conduit between online marketplaces and their suppliers to enable growth. We also have a great opportunity to tap into the wealth of marketplace knowledge and expertise within the Marketplacer team through more sharing of content and education with our community."
