Kaggle
Online platform for data scientists and ML engineers offering AI competitions, public datasets, notebooks, models and benchmarks, used by companies, researchers and learners.
Kaggle is a Google-owned platform where machine learning practitioners compete in AI challenges, share datasets, models and code in free cloud notebooks, and take Kaggle Learn courses. It also runs crowdsourced benchmarks for evaluating AI models and agents. Companies and research labs sponsor competitions and benchmarks to reach the community, and in March 2026 Kaggle opened Community Hackathons to any host. Founded in 2010 by Anthony Goldbloom and Ben Hamner, it raised about $12.5M in 2011 and was acquired by Google in March 2017. It had passed 29M registered users by February 2026, and its own materials cite 30M+. D. Sculley has been CEO since 2022.
