Snorkel AI founder Alex Ratner announced a $350M Series E at a $3.5B valuation, led by Insight Partners and S32. Since launching its Data-as-a-Service offering, the company has grown 18x+ in 12 months and passed $375M in annual run-rate revenue this week. Ratner argues that as models approach superhuman capabilities, AI data and environment development must evolve too — basic staffing and crowdsourcing approaches are no longer sufficient.
