The funding brings OneSignal's total investment since founding to more than $80 million, 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, Yes.vc, HubSpot, and Y Combinator.
