Ryan Mulvany is the founder of Quiverr, an industry-leading Amazon brand management and marketing agency.

Everyone has vices. Ryan's is selling.

It started with used books. Then new books. Then toys. And games. And foods. And soaps. And beauty products. And tech. And yes, even Justin Bieber pillow cases at one point.

His addiction spawned a business (Quiverr). His business spawned brands. Those brands paved an educational foundation which allowed Ryan and his team to build and deploy Amazon strategies for even bigger brands.

They got bigger. And bigger. From 2014–2017, they were San Diego's third fastest-growing company. Amazon awarded his firm with a platinum seller status.

And in 2017, his selling addiction peaked and he sold the entire business to a strategic partner, Advantage Sales and Marketing.

Now, Quiverr focuses on providing Amazon solutions for the top recognized CPG organizations and their assets. He's still addicted. And—since Jeff Bezos keeps saying it's only day one—he's not quitting anytime soon.
