Meet Marc Schwartz, Founder
Decades of marketing experience. Many years of hands-on work across Amazon, Walmart.com and Shopify.

Leadership with depth behind it
DMM brings together skilled people across marketplace operations, advertising, content, graphic design and technical implementation. Specialists handle the work their expertise calls for, with clear responsibilities and experienced oversight.
Our process begins with the business problem, then brings the right people and tools to it. AI can assist production and analysis; human judgment guides the brief, product accuracy and final review.
Discuss Your Business with DMM
Choose how we work together
Some businesses need ongoing execution; others need a focused review or guidance for an internal team. DMM offers account management, hourly consulting, and one-on-one coaching so the scope can match the work you need.
Start with your products, current challenges, and goals. We can then discuss responsibilities, priorities, and fees before work begins. If you prefer self-paced learning, preview AMZ Blueprint training.
