Verified event date: Snorkel AI announced a $350 million Series E at a $3.5 billion valuation on Sep 22, 2026, co-led by Insight Partners and S32, per its press release and Reuters. Snorkel calls itself the frontier AI data lab.
Reuters says its CEO put the annualized revenue run-rate at about $350 million, and that frontier AI labs need more complex data to train new models.
The $350 million and $3.5 billion figures match Snorkel and Reuters. The post says Oct 10; the announcement and Reuters report are dated Sep 22, 2026. 'Nearly triple its last mark' is not seen in the excerpts read, so unsupported here, not refuted. 'The input side is the expensive part' is the author's.
