OneSignal Raises $50M in Series C Funding

OneSignal, a San Mateo, CA-based customer engagement platform provider, raised $50M in Series C funding.

The funding, which brought total funding since founding to more than $80m, was led by BAM Elevate, an investment division of Balyasny Asset Management, with participation from Nimble Partners and existing investors SignalFire and Zach Coelius. They will join OneSignal’s other existing investors, including Rakuten Ventures,, HubSpot, and Y Combinator. 

The company intends to use the funds to advance its unified messaging and orchestration capabilities, enhance its mobile data-driven email product, and deepen its geographic presence in Europe, Asia, and Latin America.

Led by George Deglin, CEO and Co-Founder, OneSignal is a customer engagement solution, powering customer journeys across mobile and web push notifications, in-app messaging, SMS, and email. The omnichannel platform enables over a million businesses to deliver 10 billion messages daily. OneSignal supports 500,000 mobile applications – nearly 15% of all apps – enabling companies in 140 countries, including Zynga, USA Today,, Upwork, Tribune, and more.

The company, which also has offices in London and Singapore, recently released Journeys, a workflow automation tool that allows businesses to customize their customer journeys to automate personalized messaging at scale. Other product focus areas include continued development of best-in-class email messaging capabilities, expanding analytics tools to provide customers with actionable insights. 

In conjunction with the round, Jamie McGurk joined the OneSignal board, bringing 20+ years of operating and investing experience. Prior to BAM Elevate, McGurk was a Managing Partner at Coatue Management and spent 7 years as an Operating Partner at Andreessen Horowitz. As an Operating Partner, he built out Andreessen Horowitz’s Corporate Development operating team and helped raise more than $20 billion in financing and close over $20 billion in M&A transaction value for various portfolio companies.
