AI-Powered ERP, MES, and Test Software

What is your company going to make? Please describe your product and what it does or will do.

We build AI-powered software that combines ERP, manufacturing execution, and test management tailored to complex engineering operations in aerospace and other advanced industries. Our product helps teams plan and execute complicated workflows with fewer errors and more efficiency.

Where do you live now, and where would the company be based after YC?

We live in Los Angeles, CA and operate as a remote team based in the US. Post-YC, we will continue to be remote but officially headquartered in Los Angeles.

Explain your decision regarding location.

We chose Los Angeles because it puts us close to many aerospace and advanced manufacturing customers while supporting a remote team culture that lets us hire talent nationwide.
