About
Snorkel AI, Inc. is a Redwood City, California-based enterprise AI data development company — venture-backed private company (raised $135 million in Series C funding in 2022 at over $1 billion valuation) — providing the Snorkel Flow platform for programmatic data labeling and AI training data management, enabling data science and ML engineering teams to create, manage, and improve labeled training datasets using programmatic labeling functions (Labeling Functions) rather than manual human annotation at scale. Founded in 2019 by Alex Ratner and Christopher Ré (Stanford University AI Lab researchers who developed the original Snorkel research project and published the foundational "Data Programming" paper demonstrating that weak supervision and programmatic labeling could generate training data at 10-100x lower cost than traditional human annotation), Snorkel AI commercializes the academic breakthrough that AI training data quality and quantity — rather than model architecture complexity alone — determines AI system performance in enterprise applications. Snorkel Flow's core capability (enabling domain experts to write Python labeling functions that programmatically annotate training data based on rules, patterns, and weak signals) was adopted by major enterprises including Google, Apple, Stanford Hospital, and US intelligence agencies for NLP, computer vision, and multimodal AI data pipeline management. The company raised $135 million Series C led by Lightspeed Venture Partners, Greylock Partners, and Bain Capital Ventures to expand enterprise sales, add multi-modal data support (images, video, audio alongside text), and develop foundation model fine-tuning capabilities for large language model customization.
