Measurence aims to transform physical stores into websites by collecting customer behavior data. Their vision is to provide stores with comprehensive customer knowledge to enable data-driven marketing and operations decisions. The first step is collecting real-life in-store customer data like foot traffic, conversion rates, time spent, and routes through the store. This data would be analyzed to generate insights from testing different marketing approaches and understanding customer loyalty through cohorts and funnels. Challenges include privacy, sensor noise, and indoor localization though WiFi.
