The round includes participation from Guillermo Rauch, founder and CEO of Vercel, who is investing in Rebill again, and a SpaceX executive investing in a personal capacity. The company was already backed by Tiger Global, Y Combinator, SV Angel, Soma Capital and Arash Ferdowsi, co-founder of Dropbox.
Rebill solves a problem faced by any company looking to sell in multiple countries: to accept the payment methods people use in each market, such as installment payments or local transfers, it typically needs to set up a company, enter into agreements with banks and payment processors, and adapt to different regulations. With Rebill, a company can collect payments as if it were local, without setting up its own entity, and manage all its collections from a single platform. It currently operates in Argentina, Brazil, Chile, Colombia, Mexico and the United States.
Its clients include the education platform Henry, travel assistance company Assist 365 and TripleTen, the US-based technology education company. In TripleTen’s case, more than 85% of its collections in Brazil are made through local payment methods.
Rebill’s management team includes Nahuel Candia, founder and CEO; Ruben Maier Enzler, co-founder and CTO; and Ariel Díaz Ailan, COO. The company started by handling recurring payments and subscriptions for digital businesses. At the request of its own clients, who needed to collect payments in other countries, it added markets until, in 2025, it developed its own infrastructure, which now operates in five Latin American countries and the United States. That same year, Francisco León, former CEO of PayU for Latin America, joined as co-founder.
The new capital will accelerate growth in those markets, deepen operations in the United States and advance its two new business lines. Rebill Treasury allows companies to manage the money they collect in different countries: hold balances in multiple currencies, convert them and pay suppliers and partners in each market, without relying on a different bank in each location. Rebill Platforms, in turn, allows software platforms and marketplaces to offer collections and payments to their own clients under their own brand, while Rebill operates the underlying infrastructure.
The company also aims to grow among larger clients: its infrastructure holds PCI DSS Level 1 certification, the highest security standard in the payments industry, and it operates under its own licenses in its main markets.
“We want collecting payments in Mexico, Brazil or the United States to be as simple for a company as collecting payments in its own country. Today, that still requires months of paperwork and agreements, and that is what holds back many companies in the region that have everything they need to grow abroad,” said Nahuel Candia, founder and CEO of Rebill. “This investment allows us to bring that simplicity to more markets and increasingly larger companies, and to support them beyond collecting payments: also in how they manage and move their money. And we want to set the standard for how a payments company uses artificial intelligence: not as an add-on, but at the heart of how we operate and serve our clients.”
