Snorkel AI raises $350 million at a $3.5 billion valuation

Snorkel AI raised a $350 million Series E led by Insight Partners and S32, lifting its valuation to $3.5 billion from $1.3 billion 17 months ago. The Stanford spinout now sells finished training datasets and simulated environments to AI labs and companies, and says its annualized revenue run rate is $375 million.
NoteThe money is following the scarce input. Labs have the compute, and what they can't scrape is expert-labeled data, which in finance means credit, fraud and compliance cases.
