# Everstring > EverString was a B2B predictive marketing and sales intelligence platform (founded 2012) that used data science and machine learning over a proprietary business data cloud for predictive lead/account scoring, account-based marketing segmentation, firmographic enrichment, similar-company discovery, ML-generated keywords, and industry classification. It was acquired by ZoomInfo in November 2019; everstring.com now redirects to ZoomInfo Operations and the standalone developer portal is largely decommissioned. This is an API Evangelist profile of the historical API surface and current public footprint. ## APIs - [EverString Enrichment API](https://developer.everstring.com/): Data cloud, AI, and ML components as a micro-service - similar-company discovery, ML-generated keywords, industry classification, and firmographic enrichment; access-token authentication.
