In 2013, Colombian businessman David Velez decided to reinvent the Brazilian banking system. He didn’t speak Portuguese, nor was he an engineer or a banker, but he did have the conviction that the system was broken and that he could fix it. And as a former Sequoia VC, he also had access to capital.

His gut instinct and market analysis were right. Today, Nubank announced a $750 million extension to its Series G (which rang in at $400 million this past January), bringing the round to a total of $1.15 billion and their valuation to $30 billion — $5 billion more than when we covered them in January.

The extension funding was led by Berkshire Hathaway, which put in $500 million, and a number of other investors.

Velez and his team decided now was a good time to raise again, because, “We saw a great opportunity in terms of growth rate and we’re very tiny when compared to the incumbents,” he told TechCrunch.”

Nubank is the biggest digital bank in the world by number of customers: 40 million. The company started as a tech company in Brazil that offered only a fee-free credit card with a line of credit of R$50 (about USD$10).

It now offers a variety of financial products, including a digital bank account, a debit card, insurance, P2P payment via Pix (the Brazilian equivalent of Zelle), loans, rewards, life insurance and an account and credit card for small business owners.

Nubank serves unbanked or underserviced citizens in Brazil — about 30% of the population — and this approach can be extremely profitable because there are many more clients available.

The banking system in Brazil is one of the few bureaucracies in the country that is actually quite skillful, but the customer service remains unbearable, and banks charge exorbitant fees for any little transaction.

Traditionally, the banking industry has been dominated by five major traditional banks: Itaú Unibanco, Banco do Brasil, Bradesco, Santander and Caixa Economica Federal.

While Brazil remains Nubank’s primary market, the company also offers services in Colombia and Mexico (services launched in Mexico in 2018). The company still only offers the credit card in both countries.

“The momentum we’re seeing in Mexico is terrific. Our Mexican credit card net promoter score (NPS) is 93, which is the highest we’ve had in Nubank history. In Brazil the highest we’ve had was 88,” Velez said.

The company has been on a hiring spree in the last few months, and brought on two heavyweight executives. Matt Swann replaced Ed Wible (the original CTO and co-founder). Wible continues to be an important player in the company, but more in a software developer capacity. Swann previously served as CTO at Bookings.com and StubHub, and as CIO of the Global Consumer Bank at Citi, so he brings years of experience of scaling tech businesses, which is what Nubank is focused on now, though Velez wouldn’t confirm which countries are next.

The other major hire, Arturo Nunez, fills the new role of chief marketing officer. Nunez was head of marketing for Apple Latin America, amongst other roles with Nike and the NBA.

It may sound a little odd for a tech company not to have had a head of marketing, but Nubank takes pride in having a $0 cost of acquisition (CAC). Instead of spending money on marketing, they spend it on customer service and then rely on word of mouth to get the word out.

Since we last spoke with Velez in January regarding the $400 million Series G, the company went from having 34 million customers to now having 40 million in a span of roughly 6 months. The funds will be used to grow the business, including hiring more people.

“We’ve seen the entire market go digital, especially people who never thought they would,” Velez said. “There is really now an avalanche of all backgrounds [of people] who are getting into digital banking.”
