The Story

Born in Japan, raised in the U.S. I've lived across Spain, Estonia, and beyond. This global perspective shapes everything I build.

After studying Environmental Engineering at Brown, I discovered my real passion: making powerful tools accessible to everyone.

I believe AI should be humanity's great equalizer: the tutors, advisors, and assistants once reserved for the privileged few should be available to all.

"AI as the glider for everyone's mind."

Frequently Asked Questions

Questions I get asked more than I'd like.

Will AI take over the world?

No. But I do worry about how it will either force us to sharpen our critical thinking or make us complacent. In many ways, it's like Up or Brave New World. The question isn't whether AI will control us, but whether we'll choose comfort over growth.

Is Japan perfect? Do you watch anime?

No, Japan is not a perfect country without flaws. And yes, I watch anime. Cowboy Bebop and Paprika are masterpieces. I will die on this hill.

Coffee or tea?

Tea. Green tea specifically. And I'm willing to change your mind on this; most green tea in the US is awful (cough cough Lipton). Try the real stuff and we'll talk.

Wait, you studied Environmental Engineering?

Yes. My advisor once said, "Now that you have a degree, I'm honestly surprised you became an engineer." I also did conservation work in Maui helping maintain Waikamoi Preserve (one of the wettest places in the world). Somehow it stayed that way even with my dry humor.

Tell me something weird about you
  • I can snap on any surface. Tables, walls, my own face. It's a gift.
  • I beat Total War: Shogun 2 on Legendary as the Tsu faction (the independent republic). If you know, you know.
  • I send postcards to friends around the world. DM me your address, I'm serious.
  • My dream is to make enough friends globally that I always have a couch to crash on.
  • I can only count to three the German way. My hands physically refuse to do it any other way.
Are you funny?

I grew up in the US of A. I don't have a sense of humour. Please don't sue me.

What's a hill you will die on?

Cowboy Bebop and Paprika are masterpieces—no debate. Also, if you're anywhere from your late teens through your early thirties, you absolutely must read The Brothers Karamazov. It will change how you see the world.
