Brazilian fintech Lerian, a developer of open-source financial infrastructure, has successfully closed an oversubscribed US$5.6 million seed funding round. Led by venture capital firm MAYA Capital, the investment validates the company's innovative approach to core banking solutions. The new capital is earmarked to enhance its technology, expand its team, and solidify its position to compete with established industry giants.


Strategic Investment and Key Backers

The funding round saw continued support from previous investors, including Norte Ventures, Supera Capital, and Crivo Ventures, who participated in Lerian's $3.4 million pre-seed round. New institutional investors Citrino and BluStone also joined, signaling strong market confidence in the startup's potential. This diverse backing underscores the growing belief in Lerian's mission to modernize the financial system's foundational technology.

Notably, the round attracted investment from Kevin Efrusy, a veteran partner from Accel known for backing Silicon Valley successes like Facebook and Spotify. Efrusy, who invested via his family office, was also an early backer of Pismo, a key Lerian competitor acquired by Visa. His involvement provides Lerian with invaluable strategic guidance and a direct link to deep industry expertise.

A Modern Approach to Core Banking

Lerian operates in the critical core banking segment, providing an operating system for banks, fintechs, and other financial services companies. Its platform connects clients directly to the Central Bank's systems through customizable and modular solutions, such as its ledger product, Midaz. This model is designed to eliminate intermediaries, reduce complexity, and accelerate the integration process for its customers.

A key differentiator for Lerian is its commitment to an open-source model, which allows clients and even rivals to use and audit its foundational technology. According to CEO Fred Amaral, this transparency fosters trust and results in a more reliable and rapidly integrated product. The company generates revenue by offering premium plugins and ancillary services while keeping its basic infrastructure free.

Fueling Growth and Future Expansion

The newly secured funds will be primarily allocated toward technological advancement, with a specific focus on integrating artificial intelligence into the platform. Lerian also plans to strategically expand its sales and customer success teams to support its growing client roster. These investments are crucial for scaling operations and enhancing its product portfolio, which includes solutions like Flowker and Tracer.

Founded by a team of industry veterans from unicorns like Dock and Bankly, Lerian is well-positioned for significant growth. The company currently serves 14 clients and aims to double that number by the end of the year, consolidating its presence in Brazil. In the medium term, the startup is preparing for international expansion, leveraging its modern architecture and native integrations with regulatory ecosystems.


This successful seed round marks a significant milestone for Lerian, validating its disruptive open-source model in the competitive fintech infrastructure market. With robust financial backing and a seasoned leadership team, the company is poised to capture a significant share of the demand for modern banking solutions. Lerian's trajectory will be closely watched as it works to redefine financial infrastructure in Brazil and beyond.
