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.
BoomTrain is profiled on the APIs.io network. Tagged areas include Company, Marketing, Personalization, Machine-Learning, and Artificial Intelligence.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/boomtrain: open an issue to ask a question, or submit a pull request to add artifacts.
