Snorkel AI — Funding & Company Data

Snorkel AI's funding trajectory demonstrates a rapid and consistent ability to attract significant capital, reflecting strong investor belief in its mission to solve the training data bottleneck in enterprise AI. The company progressed from a combined Seed and Series A of $15.25 million in 2020 to a $100 million Series D by mid-2025, achieving a $1.3 billion valuation. This valuation, a modest 30% increase from its 2021 Series C, suggests a market correction rather than a slowdown, as the company's business reportedly bounced back strongly in 2023 after a brief pause following the launch of ChatGPT.

The investor syndicate is a key strength, comprising a mix of highly respected venture capital firms (Addition, Greylock, Lightspeed) and strategic corporate investors (GV, BlackRock, BNY Mellon, QBE Ventures, Accenture Ventures). This blend provides not only capital but also deep industry expertise and potential customer pathways, particularly in the financial services and government sectors, where In-Q-Tel's early involvement is notable. The consistent participation of early investors in later rounds signals ongoing confidence in the company's direction and execution.

With over $235 million in known funding, Snorkel AI appears to have a substantial runway to navigate the competitive AI infrastructure market. The capital from the Series D is earmarked for expanding engineering, research, and go-to-market efforts. This financial stability allows the company to compete effectively against other data labeling and AI platform players like Scale AI and Labelbox by focusing on its unique programmatic, data-centric approach. The company's pivot to emphasize evaluation and fine-tuning of large language models (LLMs) shows an ability to adapt to market shifts, positioning it to capture a critical and growing segment of the enterprise AI workflow.
