SWARM enables brick and mortar retailers to increase revenue through real-time shopper interaction and analytics. By interacting with customers in-store on a one-to-one basis on their smartphone, retailers are able to increase shopper conversion rates, decrease losses due to price comparison, and increase average ticket and lifetime value. SWARM measures in-store traffic and customer behavior by detecting signal given off by smartphones, and by delivering targeted promotions and content via a proprietary in-store wireless network.
