Instantly visualize the addressable market size, economic potential, and purchasing trends of every audience group across Amazon, Walmart, and other leading retailers. From market share and retention rates to share of wallet and product-level preferences, you’ll see exactly how each audience engages across channels.

These insights empower you to craft precise strategies that resonate—so you can reach the right shoppers with the right message at the perfect time.

Audience analytics

Pinpoint the most important audiences—and easily see the size and economics of each.

Every audience is unique—and understanding what motivates them is essential to winning market share. Our audience analytics module uses AI to identify the most important audiences for your brand and analyzes their behaviors across the retail landscape.

Instantly visualize critical performance metrics—market share, sales velocity, retention, churn, share of wallet, and market basket composition—broken down by each segment you care about most.
