$20M in Series C Funding to Transform Real-time Comms

Led by Sapphire Ventures, New Investment Will Accelerate Growth and Focus on IoT

SAN FRANCISCO — July 1, 2015 — PubNub, the leading Data Stream Network for mobile applications and IoT (Internet of Things), today announced that it has secured $20 million in Series C funding led by Sapphire Ventures  with participation from existing investors, Relay Ventures and Scale Venture Partners. PubNub will use this latest round of capital to fuel its global growth and cement its position as the leading Data Stream Network specifically designed for secure, real-time communication over the Internet. The funds will also accelerate PubNub’s plans to scale up sales and marketing operations to meet the rapidly increasing demand for its real-time Data Stream Network. “Sapphire Ventures is thrilled to back PubNub and lead this financing as the company is experiencing remarkable growth in usage and number of messages delivered per second globally,” said Jai Das, managing director, Sapphire Ventures. “We’re seeing a paradigm shift from data at rest to data in motion, but the infrastructure needed to scale and connect real-time data streams for app-to-app communications as well as for communications between IoT devices is costly and cumbersome. PubNub’s global Data Stream Network is an API-based service that solves both the scaling and security challenges of real-time data streams for web and mobile applications as well as IoT devices. The customer feedback for the company’s service was off the charts and we see a bright future ahead.”   Unlike traditional Internet request/response communication models, PubNub enables two-way communication and device control in 1
