About Jigsaw
Summary
Jigsaw builds post-training data for recursive self-improvement, selling to frontier AI labs working toward advanced AI systems. The team converts AI research and development into verifiable, gradable tasks, then supplies the resulting artifacts as post-training data, replacing the ad-hoc and hard-to-evaluate methods labs currently use to generate training signal for self-improving models.
Go-to-market
Frontier AI research labs are the direct customer, engaged through a research-partnership model rather than self-serve, as Jigsaw works with them to produce custom post-training artifacts.
