PubNub has raised $129.0M in total across 5 funding rounds.
PubNub delivers a real-time communication platform and infrastructure-as-a-service, enabling developers to build interactive web, mobile, and IoT applications. Its core is a publish-subscribe messaging API, leveraging a global data stream network for low-latency and scalability. The platform provides functionalities for chat, live engagement, and multi-user collaboration, all supported by extensive SDKs.
Founded in 2010 by Stephen Blum and Todd Greene, PubNub originated from the insight that developers needed streamlined infrastructure to easily integrate real-time capabilities. Their vision aimed to abstract data streaming complexities, facilitating dynamic digital experiences without extensive backend management.
The platform serves developers across industries like sports, media, gaming, digital healthcare, finance, and logistics. PubNub's vision empowers these developers to deliver consistent, live interactivity at scale, simplifying the creation and optimization of applications that continuously engage users.
Key people at PubNub.
PubNub is a San Francisco-based real-time communication platform and infrastructure-as-a-service (IaaS) provider that enables developers to build scalable web, mobile, and IoT applications using a global publish/subscribe (pub/sub) messaging API.[1][2][3] It serves industries like gaming, healthcare, e-commerce, logistics, and more by powering features such as chat, live updates, presence detection, collaboration, and IoT device control, handling 3 trillion API transactions monthly across 800 million devices with under 30ms global latency.[3][6] The platform solves the complexity of real-time data streaming, ensuring reliable delivery, security (AES/TLS encryption, HIPAA/GDPR compliance), and unlimited scalability without managing infrastructure.[2][3][6]
PubNub's growth is evidenced by its expansion to 15 global data centers, 70+ SDKs for languages like JavaScript, iOS, Android, and IoT boards (Raspberry Pi, Arduino), plus tools like Functions for serverless microservices and Illuminate for real-time analytics and decisioning.[1][2][6] This allows rapid deployment of interactive experiences, boosting user engagement and retention in apps from fan interactions to patient care.[3]
PubNub was founded in 2010 by Stephen Blum and Todd Greene in San Francisco, with additional offices in Mountain View (CA), Eindhoven (Netherlands), and Cambridge (UK).[1][4] Blum and Greene, leveraging expertise in real-time networking, created the company to simplify global data stream infrastructure amid rising demand for instant app communication.[1][4] Early traction came quickly: a $4.5M Series A in 2012 from Relay Ventures and TiE Angels, followed by an $11M Series B in 2013 from Scale Venture Partners and others, fueling network expansion and SDK development.[1] Pivotal moments include scaling to a trillion messages monthly and securing over 60 patent claims for its pub/sub technology.[3][6]
PubNub stands out in real-time infrastructure through:
PubNub rides the explosive growth of real-time applications fueled by edge computing, 5G, and IoT proliferation, where instant data syncing is essential for collaborative tools, live dashboards, gaming, and telemetry.[2][3][8] Timing aligns with surging demand post-2020 for remote engagement (e.g., HIPAA-compliant healthcare chat) and scalable interactivity amid cloud-native shifts, positioning it ahead of fragmented alternatives.[3][6] Market forces like unlimited device connectivity (800M+ served) and low-latency needs favor its distributed architecture over self-built solutions, reducing dev time by providing "building blocks" for 40+ industries.[3][6] It influences the ecosystem by accelerating real-time adoption—customers often add 3+ features within 18 months—while its patents and network set reliability benchmarks, enabling startups and enterprises to monetize interactivity without ops overhead.[1][6]
PubNub is primed for expansion as AI-driven real-time experiences (e.g., adaptive personalization via Illuminate) converge with Web3, AR/VR, and autonomous systems, potentially scaling beyond 3T transactions amid IoT's projected trillions of devices.[3][6][8] Trends like serverless edge computing and zero-trust security will amplify its moat, with Illuminate evolving into full adaptive intelligence for fraud/LiveOps at planetary scale.[6] Its influence may grow through deeper integrations and acquisitions, solidifying PubNub as the backbone for business-critical real-time apps—echoing its origin as a dev-friendly DSN now powering global interactivity.[1][3]
PubNub has raised $129.0M across 5 funding rounds. Most recently, it raised $65.0M Series E in November 2021.
