Snorkel raises $350 million to scale data factory for frontier AI
The US startup works with leading AI labs and enterprises on the data behind frontier model evaluation and training. The investment will expand Snorkel’s agentic data factory, which supplies the data and environments behind advanced AI lab systems.
US startup Snorkel AI has announced that it raised USD 350 million at a valuation of USD 3.5 billion in a round co-led by Insight Partners and S32, with significant participation from existing investor Addition.
The round included new investors March Capital, Blumberg Capital, Allegis Capital, Frontline, Standard, and Third Point Ventures, along with existing investors Greylock, Lightspeed, GV, Factory, Prosperity7, Walden Catalyst, and Wells Fargo, Snorkel AI said in a press release.
The investment will expand Snorkel’s agentic data factory, which supplies the data and environments behind advanced AI lab systems. The company works with leading AI labs and enterprises on the data behind frontier model evaluation and training.
“The teams pushing the frontier want a research data partner who pioneers the science of data development,” said Alex Ratner, co-founder and CEO of Snorkel AI. “That’s what Snorkel was built to be: the frontier lab for agentic data, combining human excellence with over a decade of research and technology.”
“Snorkel’s research-grade approach to AI data, environments, and measurement is becoming an increasingly important ingredient in building capable and reliable AI systems – and their demonstrated growth at scale reflects that,” said Lonne Jaffe, Managing Director at Insight Partners. “We’re excited to back Alex and the team as they continue to bring their frontier AI data factory capabilities to longer-running, complex work in high value industries like healthcare, law, and software engineering.”
Snorkel plans to use the funding to grow the capacity of its agentic data factory to meet demand, accelerate investment in vertical and enterprise AI, and extend its core research and technology into new domains and modalities. The company will also deepen its investment in open research, building on programs like its Open Benchmarks Grants initiative, the press release said.
“Snorkel’s expert-agentic environments create a unique flywheel between human expertise and AI, delivering data at the speed and quality that enables a new era of efficiency and accuracy for model development,” said Andy Harrison, CEO and General Partner of S32.
