About
The history of Open is the history of its brands. Each with a unique personality and relevance in the Brazilian credit market.
Geru was born in 2015 with the purpose of improving people's lives with a completely new credit experience. Simple. Fast. Fair.
in 2016, Biz was created–a company determined to provide resources so entrepreneurs from all over the country could thrive and make a positivel impact in Brazil.
Rebel was founded in 2017. And it immediately stirred the market with new questions, new perspectives, and, more than anything, new ideas.
2019 is the year BoletoFlex was founded, focused on enabling innovations in the digital payment methods to the Brazilian consumer.
In 2023, all these brands came together in the Open Co group to deliver the best credit solutions for individuals and SMEs from all corners of the country.
Today, the operation is divided between the Geru and Biz brands. Geru, for individuals. Biz, for small and medium-sized businesses.
And our commitment remains the same since 2013: to reinvent, include, and transform the purchasing power of brazilians.
The future is Open. And so is the present.
