Full-Service Amazon Growth. Governed by Ex-Amazon Operators.

SalesDuo is a full-service Amazon and marketplace management partner helping brands achieve profitable, operationally stable growth across Seller Central, Vendor Central, and emerging global marketplaces. Led by ex-Amazon specialists, we combine compliance-first catalog governance, advanced retail operations, and performance marketing with a P&L-driven execution model. Our structured workflows, forecasting frameworks, and AI-assisted micro-tools enable consistent scaling, Buy Box ownership, and account health protection. From listing optimization and A+ content to PPC, inventory planning, and account recovery, every engagement is built around measurable business outcomes — not activity. We work best with brands that view marketplaces as a core revenue channel and need a reliable, data-driven team to operate and scale it end-to-end. • Amazon Seller & Vendor Central Management • Marketplace Launch & Expansion • Amazon PPC & Retail Media • Catalog & A+ Content Optimization • Account Health & Compliance Governance • Inventory Planning & Profitability Modeling • Buy Box & Conversion Rate Optimization • Competitive & Growth Strategy

A small group of your customers is driving most of your value. You're probably treating them like everyone else. DAS is a customer intelligence agency. We work with DTC brands that have built real revenue — $35M to $100M — but are watching margins compress and acquisition/retention performance plateau. The issue is almost never the creative or the campaigns. It's that no one has done the foundational work of understanding who your best customers actually are. We start with your data, not your campaigns. Our process maps your customer file through RFM segmentation and cohort analysis, identifies where margin is leaking, and builds the targeting and retention infrastructure that makes every downstream investment more efficient. We take on 12-15 brands per year. Typical engagements run 4+ years. Clients include Koia, Leesa, Chomps, AMIRI, and GT's Living Foods. If you've worked with skilled execution agencies and still aren't seeing compounding results, that's the gap we close.
