Company
Greylock Partners is a venture capital firm that backs early-stage tech startups, with a long history in enterprise software and consumer apps.
Insight Partners and S32 led $350 million into a business that ships graded tasks, rubrics and reinforcement-learning environments to frontier labs. The price works out near ten times a company-reported run-rate.
Reality
Insight Partners and S32 co-led $350m at a valuation nearly 2.7 times the one Snorkel took in May 2025. The $375m figure underneath it is an annualized run rate, and the company's own launch dates for the service that produced it do not agree.
Reality
The $350m Series E values Snorkel AI at $3.5b, roughly nine times the annualized revenue it reports. What a customer buys now is a written evaluation rubric, a graded dataset and a sandbox to train in.
Reality
The pitch is a software-style test loop for machines: model a customer's own hardware and sensors, calibrate against real runs, then try thousands of scenarios before booking rig time. Ring says the match held on scenarios it withheld.
Reality
Lightfield says legacy CRM fields were written for humans and confuse agents, and its own record is open over the Model Context Protocol, which is also the cheapest way to leave Salesforce exactly where it is.
Reality
Greylock led a $32m Series A into a New York simulation platform whose strongest commercial evidence is Ring's chief product officer saying, on the record, that the simulations matched physical test results on scenarios withheld from calibration.
Reality
Andreessen Horowitz led the $47m round on the argument that agents cannot reason from fields a human typed after the call, which is a thesis about who ends up owning the customer record rather than a demonstration that anyone will pay for a new one.
Reality
Upwind's Series C more than doubles the company's price since January and funds runtime collection pulled out of the Linux kernel, but it records what five investors will underwrite rather than what cloud security buyers have already bought.
Reality
The Series C values the company at $3.8bn, double its January mark. The only number a buyer can act on is the refresh rate. A 30-second cadence only pays for itself if someone is on the other end of the diff.
