Saldo.mx is a digital wallet and bill payment platform founded in 2010 by Marco Montes, designed to facilitate cross-border remittances from the United States to Mexico. The platform allows users living abroad, particularly Mexican immigrants in the U.S., to pay utility bills, phone bills, mortgages, and mobile airtime recharges for their families in Mexico directly from their smartphones. Saldo.mx initially utilized blockchain technology, starting with the Ripple protocol before transitioning to the Stellar network, offering a digital peso stablecoin to enable faster and more cost-effective remittance services. The company addresses a critical need in a market where Mexico receives billions of dollars in annual remittances, targeting unbanked and underbanked populations who require accessible financial services. The platform operates with a self-custody wallet model that emphasizes security through bank-level encryption and multi-factor authentication, allowing users to manage funds without sharing banking information with service providers. According to available data, Saldo.mx reached approximately $1.1 million in revenue in 2024 with around 22,000 customers and maintains a small team of approximately 9 employees. The company remains bootstrapped and continues to serve the U.S.-Mexico remittance corridor, focusing on making cross-border bill payments more accessible, secure, and affordable for migrant communities. While the company's early positioning emphasized blockchain innovation, its core value proposition centers on practical remittance and bill payment services for the diaspora market.
