What it does Self-optimizing neocloud that cuts LLM bills by 80% (source)
Example from a real report (our sample on Target): “Target eliminated approximately 1,800 corporate positions, with around 1,000 employees receiving layoff notices and the remainder accounted for by eliminating open roles.” Source: NBC News
Understudy is an inference cloud. We capture your AI work traces, train smaller models, and automatically deploy them (only when they outperform the expensive model you are currently paying for).
Instead of renting the same frontier model forever, your AI infrastructure gets faster, smarter, and cheaper every time it runs.
Suppose your product uses Claude for a repetitive legal workflow.
Understudy observes successful production runs, learns the specific tools and judgment required for that workflow, and trains a specialized open-weight model.
Once that model matches or beats Claude on a held-out evaluation, Understudy starts routing production traffic to it.
As more work is completed, the model keeps improving.
We started Understudy because we believe every company using AI should be accumulating intelligence, not accumulating API bills.

Is this you?
If you're behind Understudy Labs: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
