8 personalization use cases
From product pages to push notifications — one relational foundation model powers every personalization surface.
Learn from the full relational graph - purchases, views, returns, reviews - producing recommendations that reflect genuine preference.
Personalize content feeds, articles, and media by learning from interaction patterns across users and content items.
Re-rank search results using relational context - what similar users clicked, purchased, and returned.
Predict the most relevant offer for each customer based on purchase history, preferences, and behavior context.
Optimize email content, timing, and product selection per recipient using relational engagement signals.
Recommend newly launched items to users based on purchase history and relational context - even with zero interaction data on the new products.
Rerank push notifications and in-app messages by predicted engagement - which message, for which user, at which moment.
Predict the optimal send time for each user based on historical open and conversion patterns across channels.
See how relational learning compares to collaborative filtering and content-based approaches.

Simply connect your data, start asking predictions, and get results.Want more control? Fine-tune the model for your specific use case.

Integrates directly with your warehouse, no additional pipeline setup.

Ask questions in plain English and let Kumo do the modeling for you.

Get clear predictions and push them instantly into your workflows.
PREDICT COUNT(transactions.*, 0, 90, days) = 0
FOR EACH customers.customer_id
WHERE COUNT(transactions.*, -60, 0, days) > 03 lines. No feature engineering. No pipeline code.
For developers
Kumo's Predictive Query Language (PQL) replaces months of feature engineering, model training, and pipeline work with a few lines of SQL-like syntax. Describe what you want to predict — Kumo handles the rest.
Get accurate predictions on relational data instantly—no training or ML setup required.
