Snorkel AI, a Redwood City, CA-based company providing an AI data development platform, raised $100M in Series D funding, at $1.3 Billion valuation.
The round was led by Addition, with participation from Prosperity 7 Ventures, existing investors Greylock and Lightspeed, and existing strategic investors including BNY and QBE Ventures.
The company intends to use the funds to accelerate its growth and support the launch of its two new product offerings: Snorkel Evaluate and Snorkel Expert Data-as-a-Service.
Led by CEO Alex Ratner, Snorkel AI is expanding its AI data development platform with the general availability of Snorkel Evaluate, enabling users to build specialized, fine-grained evaluation of models and agents. Emowered by its programmatic approach to curating AI ready data, this new offering allows enterprises to scale their evaluation workflows to confidently deploy AI systems to production.
Snorkel Expert Data-as-a-Service delivers expert datasets for frontier AI system evaluation and tuning to enterprises.
LLM developers are already using it to create datasets for advanced reasoning, agentic tool use, multi-turn user interaction, and domain-specific knowledge.
The round brought Snorkel AIʼs total funding to $237M since its founding in 2019.
