QI Tech Expands Market Reach With $63 Million Series B Extension in Brazil

QI Tech Series B has been extended with a new US$63 million round led by General Atlantic, strengthening the Brazilian unicorn’s role as the country’s leading financial infrastructure provider. The round also had the participation of Across Capital. Founded in São Paulo in 2018, QI Techprovides full-stack financial infrastructure via API, licensed by the Central Bank of Brazil.

With this new capital, QI Tech round reaffirms its position as the largest custodian of FIDC funds in Brazil, overseeing US$17 billion in assets under custody and US$25 billion in assets under management. Its infrastructure serves more than 400 clients, including 99, Shopee, and QuintoAndar, with products covering account origination, payments, collections, credit underwriting, anti-fraud tools, and digital onboarding.

The company achieved unicorn status in 2023 after a US$200 million Series B led by General Atlantic, and it has consistently used equity capital to accelerate growth in both product development and strategic acquisitions.

Innovation and Expansion Purpose in QI Tech Funding

QI Tech’s expansion is driven by its ability to anticipate market shifts and deploy infrastructure ahead of regulatory or competitive moves:

• Insurance-as-a-Service: Launched mid-2025, it generated US$27 million in premiums within six months—more than all insurtechs in SUSEP’s sandbox combined.
• Foreign Exchange Infrastructure: Under development to enable fast, fully digital FX transactions, removing dependency on SWIFT and streamlining compliance.
• Pix Installment Payments: Rolled out QI Fatura ahead of the Central Bank’s Pix Parcelado, giving clients a first-mover advantage.

The company’s acquisition strategy—Zaig (anti-fraud/credit engine, 2021), Singulare (brokerage & FIDC custody, 2023), and Builders Bank (white-label banking platform, 2023)—has strengthened its position as a full-stack provider capable of supporting fintechs, asset managers, and enterprises at scale.

Market Context and Competitive Edge

Brazil’s fintech market is one of the most dynamic globally, driven by regulatory modernization, open finance, and consumer demand for digital-first solutions. While payment platforms and neobanks have dominated headlines, the infrastructure layer—which enables these services—has emerged as a critical competitive battlefield.

QI Tech operates in this “engine room” of financial services, offering modular, API-based infrastructure that allows companies to embed finance directly into their customer journeys. Its value proposition is in reducing time-to-market for new financial products, improving compliance through built-in regulatory processes, and scaling transaction volumes without compromising security.

The QI Tech Series B extension will be used to expand product lines, invest in technology to handle higher transaction loads, and fund targeted acquisitions in custody, fund administration, and other complementary segments.

QI Tech Funding Related Market Movement: IORQ Launch

Adding to the infrastructure momentum, IORQ—founded by fintech veterans, including former QI Tech CEO Beatriz Degani and mogul investor Patrick Sigrist—launched this month with a Series A backed by Monashees, Upload Ventures, ONEVC, and Norte Ventures. Offering modular credit infrastructure via APIs, IORQ’s institutional ties to QI Tech suggest potential for collaboration or ecosystem synergies.
