Case Study: Disprz achieves scalable, low-latency live learning and collaborative chat for thousands of users with PubNub

How Disprz scaled their real-time chat and virtual whiteboards to thousands of concurrent users and are growing 30% QoQ

Disprz is a next-generation eLearning and employee-engagement platform (founded 2015) that delivers micro-learning, gamification, chat-based learning and AI recommendations to organizations across the US, India, Middle East and Southeast Asia. As its audience grew 30% quarter-over-quarter, Disprz’s in-house Socket.IO stack hit capacity (~2,000 concurrent users) while the platform required roughly 7,500 concurrent connections and reliable realtime features such as group chat and collaborative whiteboards (e.g., 150 participants per session across 50 concurrent sessions).

Disprz migrated to PubNub’s hosted realtime platform— a transition completed in under a month—gaining scalable, low-latency messaging backed by excellent documentation and support. PubNub’s global presence (15 points-of-presence) and 250 ms latency SLA let Disprz meet its scalability goals without performance loss, enabling continued growth and international expansion.
