Our take

OneSignal was born out of the frustration of game developers with existing push notification tools, that were not developer-friendly and did not give them a good way to re-engage users and bring them back into the game. After building its own push notification system to address these issues, the company quickly found a market gap for an easy, developer-friendly push notification system for all apps, that could be utilised by any size company.

Today, they are a customer engagement platform of choice implemented by over 1 million businesses. OneSignal's web and mobile SDK is simple for developers to install, and for marketers to use, supplying omnichannel messaging across web-and-mobile push, in-app messaging, SMS, and email.

Although there is notable competition in the space, from companies such as Braze and CleverTap, OneSignal claims uniqueness with its focus on “intelligent delivery”, which schedules notifications for the time of day users most interact with the app. The company has raised substantial funds, both in the past and more recently, that will be invested in machine learning projects, geographic expansion, and growing its team.
