Argentina’s Rebill raises $5.4 million pre-Series A to simplify cross-border payments in Latin America and the US

Rebill, the Argentine payments infrastructure company, has closed a $5.4 million pre-Series A round, bringing total funding raised since its 2020 launch to more than $9 million. For high-risk and cross-border merchants, the point is simple: if you want to collect locally in each market without setting up separate entities, bank relationships, and payment setups everywhere, this is the kind of stack you look at.

1. The round included Guillermo Rauch, founder and CEO of Vercel, who invested in Rebill again, plus a SpaceX executive investing in a personal capacity. Existing backers also include Tiger Global, Y Combinator, SV Angel, Soma Capital, and Arash Ferdowsi, cofounder of Dropbox.
2. Rebill says it solves a familiar pain point for companies selling in multiple countries: to accept local payment methods such as instalments or local bank transfers, merchants usually have to open a company, sign agreements with banks and processors, and adapt to different regulations. Rebill’s pitch is that a business can charge “as if it were local” without creating its own entity, while managing all collections from one platform.
3. The company currently operates in Argentina, Brazil, Chile, Colombia, Mexico, and the United States. Its clients include Henry, Assist 365, and TripleTen, a US-based tech training company. In TripleTen’s case, more than 85% of its collections in Brazil are processed with local payment methods.
4. Rebill’s management team includes Nahuel Candia, founder and CEO; Ruben Maier Enzler, cofounder and CTO; and Ariel Díaz Ailan, COO. The company started by solving recurring billing and subscriptions for digital businesses, then expanded into new markets at customer request, and in 2025 it built its own infrastructure, which now operates in five countries in Latin America and the United States. Francisco León, former CEO of PayU for Latin America, joined as cofounder in 2025.
5. The new capital will be used to accelerate growth in those markets, deepen its US operation, and push two new lines of business: Rebill Treasury, which lets companies manage funds collected in different countries by holding balances in multiple currencies, converting them, and paying vendors and partners locally; and Rebill Platforms, which lets software platforms and marketplaces offer collections and payouts to their own customers under their own brand while Rebill runs the infrastructure behind the scenes.

Rebill is also targeting larger merchants. Its infrastructure is PCI DSS Level 1 certified, the top security standard in payments, and it operates with its own licenses in its main markets. In practice, that combination matters when the buyer is asking not just “can you process payments?” but “can you do it at scale, across borders, without turning compliance into a months-long project?”
