Who we are

At R2, we believe that small and medium businesses are the productive engine of society. Small and medium businesses (SMBs) make up over 90% of companies in Latin America, yet they face a trillion-dollar credit gap. Our mission is to unlock SMBs’ potential by providing financial solutions that are tailored to their needs. We are reimagining the financial infrastructure of Latin America - where SMBs financial needs are satisfied without ever having to go to a bank.


R2 enables platforms in Latin America to embed financial services that SMBs can then leverage (starting with revenue-based financing and buy now pay later for business customers). We are a tight knit team coming from organizations such as Google, Amazon, Nubank, Uber, Capital One, Mercado Libre, Globant, J.P. Morgan, and Ualá. We are backed by world-class investors such as Gradient Ventures (Google’s AI-focused fund), COMETA, General Catalyst, Hi Ventures, Y Combinator, Femsa Ventures, Prosus, Endeavor Catalyst, among others.
