About the customer
Founded in Chile in 2018, Global66 is a prominent fintech player created to tackle the high costs, slow processing times, and lack of transparency traditionally tied to cross-border money movement in Latin America.
The fintech started with international money transfers and has since grown into a broader financial ecosystem centred around its Global Account. At the centre of this proposition is a multi-currency digital wallet that helps people and businesses in Latin America move, grow and manage money across borders from one app.

The Global Account lets customers hold, convert, send and receive money across currencies. It is supported by debit-card functionality, local and international account features, savings products and B2B financial services.
Today, Global66 operates across Chile, Colombia, Peru, Mexico, Argentina, Ecuador, Costa Rica, Paraguay and the United States, supporting transfers to more than 70 countries. With more than 400 employees and over 3 million users across its platform, Global66 has become one of the region’s recognised cross-border fintech players, competing in areas long dominated by banks and remittance providers.

The challenge
Scaling cross-border finance without core complexity
To scale its multi-currency wallet across Latin American markets, Global66 required a core banking infrastructure that could match its pace of growth.
Building and maintaining its own ledger and account-management system would have pulled engineering resources away from the customer-facing products that set Global66 apart.
The team needed to manage complex accounts, balances, deposits, and multi-currency transactions safely and reliably at scale. Ultimately, Global66 wanted a partner that could support scale and configurability without forcing the business into a rigid core model.
It also needed a core banking platform that could adapt to different branches, instances, currencies and products as the company expanded into new markets.

The solution
A cloud-native deposits engine for the Global Account
Global66 selected Mambu's cloud-native, API-first deposits engine at the end of 2019 to power the core of its Global Account proposition, including its digital wallets and savings accounts.
Mambu’s composable architecture integrated seamlessly into Global66's microservices ecosystem, allowing the fintech to select and combine the components it needed instead of being locked into a rigid monolith.
Through Mambu’s RESTful APIs, Global66 could automate client and account creation, execute transactions and manage configuration programmatically.

Through Mambu’s RESTful APIs, Global66 could automate client and account creation, execute transactions and manage configuration programmatically.
Running on Amazon Web Services (AWS) as its cloud backbone, the deployment gave Global66 structural elasticity, high availability, and rapid multi-country reach without requiring any local nor self managed data-center infrastructure. This modern setup allowed Global66 to connect Mambu to its broader stack, including treasury, customer apps, payment partners, local pay-in and pay-out providers, and specialised technology partners such as Jumio for automated identity verification.
Mambu’s API-first design also supports Global66’s wider AI-first strategy. Structured access to account and transaction data helps Global66 build and scale AI and machine-learning use cases across fraud prevention, transaction-risk management, business onboarding and customer experience.

“Engaging Mambu was the clear solution: its modern, cloud-native, and API-first architecture provides the seamless integration we need, while its high level of configurability ensures we can move in any direction.”

The implementation
Designed for multi-market scale from the strart
Global66 invested time upfront in designing the branch structure, instances and operating model needed to support multiple countries, currencies and products.
Mambu’s team supported Global66 through platform configuration and integration design, helping align the deposits engine with its existing microservices architecture. Because Mambu is API-first and well documented, Global66 could connect it to treasury, customer apps, payment partners and local pay-in and pay-out providers through its own integration layer.
The result was a core setup built for scale from day one, giving Global66 the flexibility to add new markets, currencies and product features without reworking its foundation.

The results
Scaling from first wallets to billions in transaction volumes
Global66 first went live on Mambu in spring 2021, creating more than 25,000 wallets on the platform in the first month of operation. Since then, Mambu has become a core foundation for Global66’s growth across B2C and B2B financial services supporting more than 3 million users across strategic Latin American corridors, including Chile, Colombia, Peru and Argentina.
In 2025, Global66 processed more than US$3.7 billion in transaction volume, a 157% year-on-year increase. B2B has become a major growth area. In that same year, Global66’s B2B transaction volume surpassed US$910 million, growing 310% year on year.
The company also processed 70% of transfers in under five minutes in 2025, demonstrating an infrastructure that supports speed as well as scale.
By the first quarter of 2026, the company reached $1.4 billion in quarterly transaction volume, processing roughly $550 million in a single month across B2C and B2B segments while securing 40,000 to 50,000 new transactional users monthly.

Scaling from first wallets to billions in transaction volumes
Looking ahead, Global66 plans to continue leveraging Mambu’s flexible core banking engine to further deepen its financial ecosystem and expand across Latin America.
The company aims to pursue an international banking license to solidify its presence, grow its B2B and SME offering, adding richer savings and account features, and building new data and AI-driven experiences for customers.
As open finance develops in Chile and across the region, Global66 sees a flexible, API-first core as a key enabler for new products, integrations and customer experiences.
“Mambu will continue to be a core foundation as we expand across more markets, currencies and customer segments, helping us bring new products, integrations and data-driven experiences to customers faster.”
