Born out of Stanford University’s Artificial Intelligence Lab in 2019, Snorkel AI sells software products that allow businesses to annotate, fine-tune and label their data. The company reached a valuation of more than $1 billion after picking up $85 million in a series C in 2021, bringing its total investment to over $135 million. The company’s tools have become a go-to for large companies like Google and furniture retailer Wayfair as well as several of the biggest American banks. In October 2024, the company added a slew of new capabilities for one of its flagship products, Snorkel Flow, including tools to assess the performance of an LLM and more easily extract information from PDFs.

Traffic estimate as of Jun 2026
Snorkel AI confirmed that it eliminated 31 of approximately 240 employees, or about 13% of its workforce. Software engineering was reportedly the most affected function. The company attributed the restructuring to a shift toward Data-as-a-Service and deprioritization of legacy business areas.
SourceThe company raised $100 million at a $1.3 billion valuation, only moderately above the $1 billion valuation reported for its 2021 Series C. Forbes characterized the relatively limited valuation increase as a possible sign of market correction or slower-than-expected growth, although the company attributed it to broader market conditions.
