Snorkel AI

Snorkel AI began as a data-centric AI platform for programmatic labeling and has shifted toward data as a service. TechCrunch reported on September 22, 2026 that it raised a $350 million Series E at a $3.5 billion valuation, which it says nearly triples the $1.3 billion valuation from a $100 million Series D 17 months earlier, led by Insight Partners and S32. Snorkel describes the raise as funding to build the frontier lab for AI data. The company says its annualised revenue run rate is $375 million, an eighteenfold increase over 12 months, though Reuters, citing the company, reported a lower figure of about $350 million via one aggregator. Total funding varies by tracker, from about $585 million across six rounds to $588 million over eight rounds.

TechCrunch notes the original business sold software for data-labeling automation, and that last year Snorkel moved to providing customers with completed datasets, so its stated focus is now a data-as-a-service approach built around expert data. Snorkel Flow is described as the flagship product, but my search found no 2026 pricing for Snorkel Flow or the expert-data offerings, so expect a sales process and custom quotes. If you were considering the original self-serve programmatic labeling approach, confirm that it is still offered as a product rather than folded into services.

Snorkel suits AI labs and enterprises that need high-quality, expert-labelled datasets and evaluation. Compare Scale AI, Labelbox and Label Studio. Browse the MLOps & Infrastructure tools directory for more.
