Top Advertising Agencies in Westport, Connecticut

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.
