Hi, I'm Pearse Taggart

Payments & Agentic Commerce Consultant

I'm a product designer and software engineer with deep experience across the payments stack. I've spent years building products that move money — from checkout flows and processor integrations to compliance frameworks and transaction monitoring systems.

My focus now is on what happens when AI agents become active participants in commerce. Autonomous agents that can discover, negotiate, purchase, and settle — and the infrastructure needed to make that safe, compliant, and scalable.

I work with companies at the intersection of payments and AI, helping them think through architecture, build prototypes, and ship products. Whether that's designing agent payment rails, integrating with existing processors, or building the interfaces that give humans oversight of autonomous transactions.

Son of the Priest

Son of the Priest is the agency name for my independent consultancy: payments infrastructure, product strategy, and agentic commerce work led by Pearse Taggart.

Pearse is the person you work with. Son of the Priest is the brand wrapper — the place for case studies, experiments, and the consultancy point of view as agent-led commerce becomes real.
