    About PubNub

    PubNub offers realtime infrastructure-as-a-service, and provides enterprise-grade security, 99.999% SLA-backed reliability, and global scalability to support the largest realtime deployments, all via simple APIs and 70+ SDKs. Additionally, developers can take advantage of value added features for application areas like chat, collaboration, IoT device control, and realtime updates to further accelerate build and release times.

    Our Vision

    PubNub set out in 2009 to develop a Data Stream Network (DSN) for developers to build realtime apps as easily as building a web page, without worrying about security, reliability, or scalability. The PubNub DSN provides global cloud infrastructure and key building blocks for realtime interactivity, and lets developers focus on customer innovation. Today, PubNub powers thousands of realtime apps around the world, from innovative start-ups to globally recognized brands, like Adobe, eBay and Samsung. We handle trillions of realtime transactions per month from over 300 million unique devices. And we offer <250 millisecond latency around the world, through our 15 global Points of Presence.

    Why Now?

    3 billion people now have smartphones, most with virtually unlimited data. Most people use their phones to read content, watch videos, and send emails. Yet the most exciting uses of our phones happens when we leverage that realtime connection to the Internet. Just think about what has changed in the 6 years: People worldwide now use their phones to order taxis, track food delivery, control their lights, and have a bunch of apps specifically for chatting with people. These apps are all powered by a new layer of technology: realtime technology. At PubNub, we call this a Data Stream Network, and our tech is used by many of the apps you already have installed on your phones, in your homes, and on your browsers.

    So how will this change the world?

    Cars, planes, and other means transportation are a leading cause of climate change. But as realtime experiences get more real, people will find fewer needs to travel to and from work, meetings, conferences, seminars, and other events. The online experience will meet, and eventually exceed, the “real-world” experience. The online tools to collaborate will get better than people standing at a whiteboard.

    Realtime technologies will also change how people attend and participate in large events, like sports matches, concerts, and speeches. Already, leading companies like Hotstar in India are using PubNub to break records by powering live audiences of 10 million plus who participate in online experiences that are synchronized with live cricket broadcasts. And people like actor and musician Jared Leto have performed in live streaming concerts where PubNub is used to provide a massive scale audience experience online.

    But that’s just getting started. Online realtime technology exposes everyone to amazing classes at the best universities. People can get medical help from experts halfway around the world. We can have deep and meaningful collaborations with people in any subject: academic, creative, and professional.

    While the rapid rise of smartphones and realtime tech like PubNub might make it feel like we’re already living in the future, we’re really just embarking on a change that will affect every person worldwide in every aspect of their lives.
