EverString was a San Mateo, California-based enterprise software company that provided a business-to-business marketing intelligence platform utilizing predictive analytics and machine learning to identify high-conversion sales leads. The software-as-a-service platform applied natural language processing, text mining, and quantitative finance mathematics to corporate decision-making, reportedly increasing customer conversion rates by more than 50 percent. Prior to its eventual acquisition by ZoomInfo in 2020, the software company secured significant venture capital backing, including a $12 million Series A round and a $65 million Series B funding round. These financing rounds were supported by major institutional investors such as Lightspeed Venture Partners, Sequoia Capital, and IDG Ventures, which helped scale the operation from 28 employees in 2014. The predictive analytics enterprise EverString was originally founded in 2012 by co-founders Vincent Yang and J.J. Kardwell.
