Hopsworks

Hopsworks provides an AI Lakehouse platform for real-time machine learning, combining a feature store with sub-millisecond online retrieval, an AI lakehouse supporting Delta, Iceberg, and Hudi table formats, and complete MLOps lifecycle management. The platform's feature store, powered by RonDB (the fastest open-source key-value store), delivers sub-millisecond latency for online feature lookups, with SIGMOD 2024 benchmarks showing 10x lower latency than SageMaker and Vertex. Hopsworks enables 80% cost reduction through feature reuse and streamlined development, with 9-45x faster reads than competing platforms. The platform integrates Claude Code and OpenAI Codex CLI for AI-assisted development, supports Spark, Flink, Pandas, and DuckDB frameworks, and offers GPU management for LLMs with Ray and KServe/vLLM. Hopsworks supports sovereign AI deployment in air-gapped, on-premises, and hybrid environments. Customers include Zalando (real-time personalization across 25 countries and 50 million customers) and Clicklease (real-time fraud detection). Founded in 2018 and headquartered in Palo Alto, United States, the company has raised approximately $12.4 million at the Series A stage.
