QI Tech, a Brazil-based FinTech company that provides financial infrastructure solutions, has raised $63m in a Series B extension round to further strengthen its position in the country’s rapidly evolving digital banking sector.
The funding round was led by global investment firm General Atlantic, with continued support from Across Capital, marking its fourth consecutive investment in QI Tech.
This extension follows the $200m Series B funding led by General Atlantic in 2023.
Founded in 2018, QI Tech offers a full-stack technology platform that enables financial institutions, FinTechs, and enterprises to build and scale financial products.
Its services span core banking, payments, lending, investments, and insurance, all integrated through APIs and underpinned by robust regulatory licences.
The company plans to use the new capital to accelerate product development, enhance its acquisition strategy, and consolidate its leadership within Brazil’s financial infrastructure. It is also targeting expansion into foreign exchange capabilities and other value-added services as part of its long-term vision.
QI Tech has pursued an aggressive acquisition strategy in recent years, acquiring anti-fraud and credit platform Zaig in 2021, and both Singulare and Builders Bank in 2023. These deals have positioned the company as Brazil’s largest FIDC custodian, it said, with $17bn in assets under custody and $25bn in assets under management, according to Anbima’s July 2025 rankings.
The firm has also entered the insurance space with its recently launched insurance-as-a-service platform, issuing over $27m in premiums in just six months. Additionally, it is building FX infrastructure to deliver seamless international transactions outside the traditional SWIFT system.
QI Tech CEO Pedro Mac Dowell said, “This new investment enhances our ability to accelerate the development of solutions aimed at modernizing Brazil’s financial infrastructure. We remain focused on expanding our portfolio with reliability, compliance, and scalability. The additional capital also positions QI Tech for strategic M&A moves aligned with our long-term vision.”
