About INT21

We are building self-improving AI systems for the software beneath modern AI. Our first product generates and optimizes low-level GPU software, then proves its work with tests and benchmarks. Today, we are launching INT21: the first company to achieve self-improving AI agent swarms, applied to AI infrastructure. That software has an outsized effect on speed and cost. The first four implementations produced by PTX Kernel Factory are open source today. The product is also entering beta, with early access available at int21.ai.

About TermRover

TermRover is a native SSH + Mosh terminal optimized for working with tmux on iPhone and Android. Browser-style tabs, one-tap prefix actions, and scrolling all just work. The tmux prefix, usually Ctrl-b, is awkward on a touchscreen. Scrolling is worse: it usually requires mouse mode and changes to .tmux.conf, with no clear indication whether it is enabled., tapping the terminal should open the keyboard, and sending a screenshot to a coding agent. It immediately made sense for a phone: SSH can drop as you move between networks, while Mosh keeps the terminal working.
