Loopd, an advanced events engagement platform, uses MongoDB to power its location-tracking platform for conferences. The company provides physical intelligence for corporate events, helping marketers understand how people interact with each other and their products. Loopd stores millions of datapoints from connected advertising and Bluetooth LE badges on the conference floor using MongoDB's time series data capabilities. The database handles heavy write operations in real-time, enabling calculations to be consistent, timely, and accurate. By switching from PostgreSQL, Loopd significantly increased its write throughput, reduced VM resource consumption, and simplified its underlying architecture.
