Case Study: Fringe81 achieves real-time user behavior analysis and dramatically lower TCO with Aerospike

Fringe81 Leverages Large Lists to Analyze User Behavior

Fringe81, a Tokyo-based software and Data Management Platform company, needed to scale its user profile store without ballooning infrastructure costs. After running into limits with memcached and DynamoDB, the team sought a solution that offered ACID reliability, high-performance writes, and easy maintenance—selecting Aerospike to meet those needs.

By using Aerospike Large Lists to store clickstreams, Fringe81 built the ListFinder feature in its Humpty smart-buying tool, enabling real-time user categorization and retargeting. Analytics that once took hours or a day now run in moments, infrastructure costs on AWS scale linearly, server count and TCO dropped significantly, engineering overhead eased, and the new functionality delivered an estimated ROI of over 300%.
