Overview
Hazelcast provides an enterprise-grade platform for real-time data processing by combining stream processing with low-latency data storage. It handles real-time data streams and stores data in-memory to enable immediate actions. The platform supports high availability and distributed processing, serving industries like financial services, e-commerce, and telecommunications that need instant insights from data. Revenue comes from software licensing, subscriptions, and professional services such as support and training. Unlike some competitors that focus on either streaming or storage alone, Hazelcast integrates both capabilities in a single unified platform, allowing customers to process and analyze data in real time and to act quickly based on up-to-the-moment information. The company aims to help businesses turn real-time data into actionable decisions, effectively using time as a competitive advantage.
