TLDR
Snorkel AI has raised a $350 million Series E at a $3.5 billion valuation, according to TechCrunch. Insight Partners and S32 led the round, which nearly tripled the startup’s valuation from its 2025 Series D. Snorkel began with data-labeling automation but now sells completed datasets and simulated environments to AI labs and companies. It says its annualized revenue run rate reached $375 million, an eighteenfold increase in a year; that is a company-reported figure, not an audited result.
