Kumo

Kumo is an AI model company that provides a platform for training and deploying state-of-the-art machine learning models on relational enterprise data. Founded in 2021 by Jure Leskovec (Stanford AI Lab professor), Hema Raghavan, and Vanja Josifovski (former CTO at Airbnb and Pinterest), Kumo uses graph neural networks and deep learning to solve predictive problems—including fraud detection, recommendations, and churn—directly on graph-structured relational data without requiring manual feature engineering. The platform is designed for data scientists and ML engineers who want to operationalize predictions from existing data warehouses. Kumo is backed by Sequoia Capital and reached $11M in ARR by 2024.
