**APIs profiled:** 0

BoomTrain was a machine-learning marketing technology startup that used AI to power personalized, cross-channel messaging (email, web, and push notifications) for brands, predicting individual content and send-time recommendations for each consumer. Backed by 500 Global (formerly 500 Startups) among others, BoomTrain raised roughly $15M before being acquired by Zeta Global in July 2017 (reportedly $35-40M), which folded its machine-learning, decisioning, and personalization technology into the Zeta Marketing Platform. The boomtrain.com domain now redirects to Zeta Global; there is no standalone BoomTrain developer portal, public API, or documentation surface. This profile is retained as a historical company record in the API Evangelist network.
