Tokyo-born · Building in New York

I build AI systems that simulate how messages land on different audiences — before they go live.

Hackathon builder, stand-up comedian, and the person behind Humor Genome, Midtown Show, and sound.fan. I use comedy as a testing ground for interpretation science — because laughter is the fastest feedback loop.

Decision Room

Practice high-stakes meetings before they happen. Present your case to an AI panel, answer tough questions, and watch how their private deliberation turns into a decision.

Three domains, one thesis

Each site explores a different layer of the same question: how do audiences interpret messages, and how can creators iterate before going live?

About

I'm Michi Yamamoto — a builder working at the intersection of AI, audience intelligence, and live performance. I build fast, test in the open, and treat every hackathon as a chance to push one thesis forward: that you can simulate how a message lands before it ships.

By night I do standup in Manhattan basements, which is where I stress-test everything I build. Comedy is the highest-bandwidth feedback loop I've found — laughter is immediate, measurable, and brutally honest.

I'm looking for investors, sponsors, and collaborators who want to back this work.
