OneSignal, the customer messaging and engagement platform, has raised a total of approximately $84M across multiple funding rounds since its founding in 2011 as a Y Combinator-backed startup.

The company's funding journey began with a pre-seed round of approximately $170,000 from Y Combinator, SV Angel, and Start Fund in 2011. This was followed by a seed round of $2.5 million in 2015, backed by Rakuten Ventures, Y Combinator, SV Angel, and angel investors including Justin Kan (co-founder of Twitch) and Zach Coelius.

In August 2017, OneSignal raised $7 million in Series A funding led by SignalFire, with participation from Rakuten Ventures and other angel investors, bringing total funding at that time to approximately $9.5 million.

The company then raised $25 million in Series B funding in July 2019, led by SignalFire with participation from Rakuten Capital. In April 2021, OneSignal secured an undisclosed corporate round in the form of a convertible note from HubSpot.

OneSignal's most recent and largest round was a $50 million Series C in September 2022, led by BAM Elevate (an investment division of Balyasny Asset Management), with participation from Nimble Partners, SignalFire, Zach Coelius, Rakuten Ventures, Yes VC, HubSpot, and Y Combinator. In January 2023, the company extended its Series C with an additional undisclosed strategic investment from ServiceNow Ventures.
