DAS Audience Development

Verified

Audience Development & Customer Intelligence Agency for Retail & Ecommerce Companies generating $10M–$100M in revenue.

Most brands treat their entire audience the same. Batch-and-blast campaigns. Identical flows for a first-time buyer and a fifth-time buyer. Segmentation that is under-segmented. Paid media eroding margins. DAS exists to fix that. We're a customer intelligence agency for brands in the $15M–$100M range. Every engagement starts with your data—purchase frequency, RFM segmentation, cohort-level LTV, and contribution margin analysis. We identify which customers are compounding value and which segments are eroding it. From there, we build the retention and acquisition architecture: lifecycle flows calibrated to actual buying behavior, campaign strategies segmented by customer value, acquisition strategies that find more of your best customers, while doing so with increased efficiency, and deploy frameworks your team owns long after we're gone. Clients include Koia, Leesa, GT's Living Foods, Create Wellness, and Hydrant. Average engagement lasts 4+ years. We take on 10-15 retainer clients per year—a deliberate constraint that keeps our team of senior operators embedded in your business, not spread across thirty accounts. If your business metrics have plateaued despite good execution, the problem probably isn't creative. It's who you're sending to and the systems that enable the marketing and advertising functions.
