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.
