## About

Based in California, US, and founded in 2021 by Anish Athalye (CTO), Curtis Northcutt (CEO), and Jonas Mueller, Cleanlab Inc. operates as a software platform that offers an open-source platform that enables automatic error detection and fixation in real-world data. In October 2025, Handshake, a portfolio company of Base10 Partners, Valiant, Coatue Management, Notable Capital, Imaginable Futures, Emerson Collective, Chan Zuckerberg Initiative, Reach Capital, Omidyar Network, EQT, Spark Capital, Lowercase Capital, Kleiner Perkins, Annox Capital, True Ventures, and Lightspeed Venture Partners, agreed to acquire Cleanlab Inc from AME Cloud Ventures, Bain Capital, Essence VC, Databricks Ventures, Samsung Venture Investment, Menlo Ventures, and TQ Ventures. The transaction was completed in January 2026.
The company provides software tools and DCAI algorithms that automatically find patterns and mistakes in large, real-world datasets that are both structured and unstructured, including visual, textual, and tabular data. The firm deploys data-driven AI (Artificial Intelligence) solutions like LLMs, ML models, and business intelligence analytics and adds smart meta-data to every data point to offer actionable insights to businesses.
The January 2025 acquisition plans to enable Handshake to strengthen its data quality and auditing capabilities for artificial intelligence model training by acqui-hiring Cleanlab Inc’s research team and integrating its algorithms into its data labeling pipeline.
