PubNub

PubNub provides infrastructure and developer tools for building and operating real-time interactive applications. Its platform combines a globally distributed messaging network with APIs, SDKs, and services for managing live application data and behavior. Product teams use it to add real-time capabilities while PubNub operates the underlying network.

The platform’s core is programmable publish/subscribe messaging: applications publish messages to channels, and connected clients receive them through subscriptions. Supporting features include presence information, message history, metadata and file storage, analytics, and logic that can run on the network. PubNub also offers integrations such as mobile push notifications and event forwarding to external systems.

Developers can use PubNub’s SDKs across web, mobile, server, and embedded environments, or access its services through APIs. The company describes use cases including chat, collaboration, live audience engagement, data streaming, IoT device control, geolocation and dispatch, and live updates. Its platform is intended to support applications that need low-latency communication and global scale.

PubNub’s network and platform include operational and security capabilities such as access controls, encryption, regional deployment options, and multi-region support. The company also provides dashboards and support services for customers. PubNub states that its platform has a 99.999% availability SLA; specific service terms and performance depend on the applicable customer agreement and configuration.

The company says it was founded in 2012 and that more than 2,000 companies worldwide use its platform. Its About page names Amazon, RingCentral, Gameloft, and DAZN among customers, and identifies The Raine Group, Sapphire, Scale, Relay, Cisco, Bosch, Ericsson, and HPE among its investors. PubNub’s operations and product history have centered on real-time infrastructure, with capabilities expanding from messaging into presence, data storage, network-based logic, regional controls, and decisioning tools.

PubNub is headquartered at 95 Third Street, Second Floor, San Francisco, California, and also lists offices in London, Katowice, and Singapore. The company’s website presents its purpose as helping product and development teams build scalable real-time applications, so they can concentrate on application features while relying on PubNub for the supporting real-time platform. Its public materials emphasize flexibility, reliability, security, and developer enablement.
