Pesito vs Nomad. A dollar account for Brazil, and one for people already here.
Nomad is a Brazilian favorite: a US checking account in dollars, a Visa debit card and US investing, with more than 3.8 million customers. It is built for Brazilians who live in Brazil and want dollars for travel, saving or investing.
That is also its limit. Nomad's own pages say it opens US accounts for Brazilians who are not US residents, with a Brazilian ID and an address in Brazil. If you live and work in the United States, or you are Mexican, Guatemalan or Salvadoran, Nomad is not built for you. Pesito is. Pesito is pre-launch.
The short answer
Pick Nomad if you are Brazilian, you live in Brazil, and you want to hold dollars, spend abroad or invest in the US.
Pick Pesito, once it launches, if you live in the US, you earn in dollars, and you want an account you open with your own country's ID that also works for your family in Mexico.
