Hi, I’m Michelle👋🏻
I publish primary-sourced research on the physical AI stack: the components, supply chains, economics, and deployment constraints that determine what actually gets built and adopted.
I use filings, visit factories, quote components first hand and talk with the people building the stack constantly - some of the conversations are released on our podcast. The goal is to answer a practical question: where does value accrue as physical AI moves from prototype to deployment?
