What does it take to build a seven-figure Amazon business from Eastern Europe? In this episode, Bradley Sutton travels to Sofia, Bulgaria, to speak with experienced sellers from Bulgaria and Romania who have built successful brands across Amazon Europe and the U.S. marketplace. From workwear and cosmetics to pet supplements and ranking services, these sellers share how they found opportunities, scaled their businesses, and adapted as Amazon continued to evolve.

The first story follows Iliyan Ivanov, a seller who started in advertising and eventually turned local workwear demand into a multi-million-euro Amazon brand. He explains how starting early in Amazon Europe gave his listings maturity, how Germany became his top marketplace, and how keyword research helped uncover unexpected seasonal demand around Germany’s carnival season. He also shares how tools like Cerebro and Managed Refund Services helped his team with listing strategy, keyword targeting, and recovering money from Amazon reimbursement opportunities.

Next, Bradley talks with another Bulgarian seller, Milcho Vasilkov, who used product research to enter categories he was not personally connected to, including maternity products, cosmetics, grocery, and pet supplements. His story highlights why sellers do not always need to be passionate users of their own products to succeed. Instead, he focuses on demand, customer behavior, marketplace fit, and smart inventory timing. He also shares Prime Day strategies for Europe, including building keyword position ahead of major events, using account managers for top deals, and extending promotional momentum after Prime Day.

The final guest brings a Romanian seller, Marcel Marculescu’s perspective on selling in the U.S. marketplace, and how Amazon ranking has changed over the years. After early product failures, he built a seven-figure Amazon business and now focuses on more sustainable launch and ranking strategies. He discusses using Vine, PPC, external traffic signals, keyword research, and Rufus optimization to help listings perform in today’s Amazon ecosystem. The episode closes with a powerful reminder for sellers: success does not come from a single hack or a single marketplace, but from adapting early, watching the data, and building strategies that can survive the next Amazon change.
