Shopper OS

Connect, engage, and retain shoppers across the retail ecosystem

Retail Checkout
Sell on your site, ship through retailers, and capture valuable shopper data.
The way shoppers buy is evolving—and your checkout experience should too.

Our checkout technology empowers brands to sell products directly on their own websites while leveraging the fulfillment power of trusted retail partners like Amazon and Walmart. Shoppers enjoy a seamless, branded purchase experience, and orders are automatically processed and shipped through retailers’ logistics networks without requiring your team to manage warehousing or last-mile delivery.

This approach means you get the best of both worlds: capturing first-party customer data to fuel remarketing and loyalty, while maintaining strong retail relationships and ensuring operational efficiency. Retailers benefit by preserving sales volume, and you gain complete visibility into your customers’ journeys—so you can build deeper connections and drive sustainable growth.
