What OneSignal does
OneSignal is a customer engagement and messaging platform founded in 2011 and headquartered in San Mateo, California, with additional offices in London and Singapore. The platform unifies mobile push, web push, email, in-app messaging, SMS, RCS, and Live Activities from a single dashboard, and is augmented by an AI personalization layer (OneSignal AI), a no-code Journey builder, behavioral segmentation, event-driven triggers, and a real-time analytics module. Underlying the product are REST APIs and lightweight SDKs for Android, iOS, Flutter, React Native, Expo, and Unity, with an emerging Model Context Protocol (MCP) interface that allows external AI agents to initiate messaging on behalf of users.
The platform operates at meaningful scale: it powers over 200,000 apps, 1.5 billion monthly active users, and 1.3 trillion messages annually across 180 countries, with 99.9% reliability and billions of messages sent per day. OneSignal serves over one million businesses ranging from early-stage startups to Fortune 500 enterprises (logos include Zynga, Whole Foods, DHL, Royal Caribbean, Porsche, Philips, Nexstar, Bitcoin.com, TAG Heuer, Zenni, Taptap Send, and Peapod) across Gaming, News/Media, eCommerce, Mobile Apps, and Fintech verticals.
The business model combines a freemium self-serve entry point with Professional and Enterprise subscription tiers and usage-based pricing on message volume across channels. Distribution is hybrid: product-led growth via self-serve SDK onboarding for SMBs, enterprise field sales with solution partners for larger accounts, and channel partners (e.g., Company 100 in Japan) plus the Google Cloud Marketplace for regional and enterprise reach. Revenue is not publicly disclosed; capital raised to date includes a $50M+ Series C in September 2022 led by BAM Elevate and a strategic investment from ServiceNow Ventures in January 2023.
