Key Benefits

bolt
Sub-100ms-class experiences

Keep conversations and AI actions feeling instant.

Benefit

Global pub/sub with low-latency delivery keeps voice, chat, and agentic workflows responsive. Customers don’t perceive lag as ‘system failure,’ and your NPS doesn’t suffer from slow infrastructure.

insights
Events that drive action, not reports

Turn live signals into automated workflows.

Predictable TCO as you scale

Control costs as engagement grows.

Benefit

Move from open-ended DIY spend and six-figure upkeep to a platform where costs map to clear drivers like active users and features, with guardrails and monitoring for high-volume events.

Your customer engagement platform can’t be real-time if your infrastructure isn’t

Ticket-centric tools, DIY WebSockets, and disconnected channels leave agents blind and AI guessing—customers feel every delay as a broken promise.

Outages and latency spikes hit at peak moments, driving up churn, support costs, and on-call fatigue while six-figure upkeep quietly drains your budget.

A managed real-time layer turns your platform into a person-centric, always-on system of action—without tying up your best engineers.

Why not build our own real-time customer engagement infrastructure?

DIY real-time stacks typically require dedicated engineers to build, scale, secure, and monitor WebSockets, presence, and history. Industry research shows many teams face outages and six-figure annual upkeep. PubNub offloads that operational burden with managed infrastructure, an uptime SLA, and a clear cost model—so your senior engineers can focus on orchestration, AI, and product differentiation.

What does a typical adoption path look like for a customer engagement platform?

Most teams start with a single high-impact use case—such as in-app support chat or agent-customer messaging—then expand to presence, collaboration signals, and event-driven automation. Once value and reliability are proven, organizations standardize PubNub as the real-time layer across channels and products, simplifying operations and cost forecasting.
