Alumni Q&A
- How did your company get started? (i.e., How did the founders meet? How did you come up with the idea? How did you decide to be a founder?)
- The founders are brothers who grew up in the Caribbean and have built projects together throughout their lives. Sergio taught himself calculus from MIT OpenCourseWare at 12, published mathematics as a teenager, and worked on AI and robotics at Stanford, Nvidia, and Google X; Luigi studied math and CS at Columbia and co-founded a payments company where he scaled engineering to billions in transaction volume.
- What is your long-term vision? If you truly succeed, what will be different about the world?
- The founders aim to build embodied artificial general intelligence, moving AI beyond screen-based problem solving into the physical world. They envision billions of robots working alongside humans to perform useful work.
Summarized from the founders' answers on their Y Combinator profile.
