I am the CEO and founder of Bobsled Marketing, a digital agency that helps consumer product brands to grow and protect their sales on Amazon. Specializing in operations, marketing and advertising on the Amazon platform, I'm watching the profound shift that's occurring for brands and retailers who are trying to figure out their business model in the Amazon age. I published "The Amazon Expansion Plan," (updated in 2018) which offers a close-up view of generating predictable results for Amazon sellers and advertisers. For readers of Forbes, I share the collective wisdom gathered through managing hundreds of brands' accounts on Amazon.
