OneSignal

OneSignal operates a B2B SaaS model built around a unified customer engagement stack. It creates value by giving businesses one system to manage messaging channels, user segmentation, event-triggered campaigns, lifecycle journeys, and delivery analytics without assembling separate vendors for push, email, SMS, and in-app messaging. Its developer tooling reduces implementation friction, while workflow automation and cross-channel orchestration increase customer dependence over time.

OneSignal is a private US-based B2B software company that provides a cloud customer engagement platform for sending and orchestrating messages across push notifications, email, SMS, RCS, in-app messaging, and live app updates. Its platform combines messaging infrastructure with segmentation, automation workflows, APIs, SDKs, analytics, and testing tools so businesses can run lifecycle marketing, retention, and re-engagement programmes across mobile apps and websites.

The company primarily serves marketing teams, growth teams, product managers, developers, publishers, app businesses, ecommerce companies, and other digital businesses. It makes money through a SaaS model that blends recurring subscription fees with usage-based charges tied to audience scale and message volume, with higher-value plans adding automation, analytics, and enterprise capabilities.
