OneSignal

Marketing · San Mateo, United States · Founded 2011

OneSignal is a customer engagement platform that specializes in push notifications. It serves a broad range of clients, from small businesses to large corporations, across various markets. The company's primary service is to help businesses connect with their customers through mobile and web push notifications. These notifications are designed to create a delightful user experience and can be personalized to target the right audience. OneSignal's business model is based on a freemium model where basic services are provided for free, and premium features are available for a fee. The company generates revenue through its premium services, which include advanced features like machine learning to optimize message delivery times and detailed analytics to track message performance. The platform is designed to be user-friendly, with a setup process that takes as little as 15 minutes. It can handle high volumes of users, sending out billions of notifications daily. OneSignal also offers a 'set it and forget it' feature, where notifications can be triggered based on user behavior. The company prides itself on its open-source SDKs and API accessibility, making it a popular choice among developers. The founders, who were developers themselves, built OneSignal to meet a personal need, and have since made it easy for any business to get up and running with the platform. Keywords: Customer Engagement, Push Notifications, Freemium Model, User-Friendly, High Volume, Behavior-Based Notifications, Machine Learning, Detailed Analytics, Open-Source SDKs, API Accessibility.
