Nu Mexico’s 15M Customers and the Speed of Digital Banking
Nu Mexico reached 15 million customers last week, after tripling its customer base in two years and adding around 12,000 new customers per day. Apart from the numbers that made it to the headlines, the bigger story is the speed at which digital banks reach scale in foreign markets.
Speed to 1 million customers is a useful signal of market readiness. GoTyme reached the milestone in the Philippines in around nine months, supported by high financial exclusion and strong digital adoption. Nubank reached 1 million in Mexico in about two years, entering a concentrated but disruption-ready banking market. Revolut took around eight years in Switzerland, where customers are already well-banked and switching inertia is high.
The pace depends on three factors: financial exclusion, competitor density, and digital readiness. Markets with unmet banking needs tend to move faster, while mature and saturated markets require a much longer conversion cycle.
Nubank’s Colombia growth shows the same pattern. Its reach rose from 8% to 11% of the adult population between Q1 and Q4 2025, making it one of Nubank’s fastest-growing international markets by penetration velocity.
For digital banks, the first million customers can reveal more than headline user numbers. It shows whether the market has unmet demand, whether incumbents are vulnerable, and whether the expansion playbook can travel.
