HPE Joins IaaS Startup PubNub’s $23M Series D

San Francisco-based infrastructure-as-a-service startup PubNub raised $23 million in Series D funding to build its international business, specifically in emerging markets. This brings the company’s funding to date to a little short of $70 million. Hewlett Packard Enterprise (HPE) joined existing investors Sapphire Ventures (which is backed by SAP), Relay Ventures, Scale Venture Partners, Cisco Investment, Bosch, and Ericsson in the latest round. Founded in 2010 by Todd Greene, now CEO, and Stephen Blum, now CTO, PubNub builds software and hardware for developers to build real-time web, mobile, and IoT applications. Its core product is a real-time publish/subscribe messaging API that is built on its global Data Stream Network (DSN).
