I’m an entrepreneur and athlete. I run Algoboa, a company in Tokyo that helps companies build AI into their everyday work. I’m also a co-founder of RIKYU, which wholesales Japanese matcha to cafés in more than ten countries, and of Next Sales, an AI sales tool now in development. Before Algoboa, I was director and CTO of an AI startup, where I led a team of about fifty people building AI systems for large manufacturers.

I was born in Brazil and grew up in Okazaki, Japan. I studied at Akita International University and started working in AI while I was still a student. My family has had a coffee farm in Paraná since the 1930s, when my great-grandfather moved to Brazil, and the name Algoboa comes from the Portuguese algo (something) and boa (good).

Outside of work I race triathlon and HYROX. Here are my results, my favorite movies and books, my journal, and some principles I try to keep in mind.

Principles

  • The top of life is health, free time, love, and beauty
    • Money is the floor
    • The body comes before the business
  • Good people, good money, good life
  • Start with things people really need
    • People will not stop drinking matcha or coffee
  • Several businesses are better than one very large company
    • They help each other
  • Value stays in what is hard to copy
    • Less in code, more in your own data, relationships, and physical things
  • With AI, what matters is how many places you create to use it
  • Test things with a hypothesis in hand
  • Work side by side instead of passing messages along
  • Build work that does not grow only with the hours put in
  • Culture from any country can travel once it is in a form that sells
