Background

Hi, I'm Pearse Taggart — a product designer and software engineer with a focus on payments and commerce. I've spent years working across the full stack, building products that move money and the interfaces people use to manage it.

Now I'm focused on what happens when AI agents become participants in commerce — and the infrastructure needed to make that work safely and at scale.
